An MTC HC Series Fuel Polishing System is the central component of a Fuel Management Plan that involves the maintenance of numerous large capacity fuel tanks or providing fuel polishing services to your customers over a wide region allowing for high volume, expedited servicing. Establishing a fuel management and maintenance protocol should include removal of accumulated water, periodic fuel circulation for particulate filtration and polishing of the fuel, and treatment with a Diesel Fuel Catalyst made to work hand-in-glove with the Fuel Polishing System to clean the fuel tank without removing the fuel, assuring that the lights stay on when the power goes off.

The MTC HC-150 Series Systems

The Mobile Tank Cleaning (MTC) High Capacity (HC) Series Systems are pallet mounted mobile Fuel Conditioning and Tank Cleaning Systems ideal for performing Fuel Polishing operations on larger holding tanks of diesel fuel, bio-fuels, light oils and hydraulic fluids. The MTC HC-150 consists of two pallets: A Pre-Filter Skid that includes the primary and secondary filtration vessels, and a Pump Skid that contains the Tertiary Filter Vessels, the Fuel Conditioners the pump & motor, and controllers. The MTC-150 is capable of cirgulating up to 150 Gallons per Minute (568 LPM). The system’s maximum flow rate depends on factors such as: suction lift, discharge head, hose length & diameter, pressure drop over the primary/secondary/tertiary filters and separator. The flow may be reduced to 10 GPM for specialty cleaning jobs.

The MTC HC-150 efficiently removes sludge, water and sediments that naturally accumulate in tanks. The MTC HC-150 system excels in low operating cost and compact design, and cleans tanks and restores fuels and oils to their "Clear & Bright" condition. It eliminates fuel "algae" issues, clogged filters, excessive exhaust smoke, and tank sludge, providing Optimal Fuel Quality for Peak Engine Performance and Reliability.

Generally the fuel conditioning and tank cleaning process involves circulating the contents of a full tank of fuel three times. If the goal is to complete a tank cleaning job within one eight hour shift, not including preparation and cleanup time, the MTC HC-150 can accomplish this on tanks up to 24,000 gallons (91,000 liters).

Applications

The AXI Mobile Tank Cleaning Systems are ideal for any individual or enterprise that has multiple tanks that require periodic cleaning to assure that fuel being consumed by equipment is in optimal condition. This could be a construction, trucking, fuel supply or filling station operator, or agricultural operation, mining or quarry operation, railroad, or a municipality with fire, police, EMS, water or sewer treatment plants, and waste disposal facilities that all require periodic service. It is also ideal for an independent maintenance service provider, such as maintaining marine vessels, backup or emergency power generators for offices, plants, data centers, or similar enterprises, cell tower generators, or other enterprises where the service provider can offer fuel and tank service assuring that fuel in storage is kept in optimal condition and fuel tanks are clean and free of water and other contamination in conjunction with providing other preventative maintenance duties such as changing oil.

Matching System Size to your Needs

Mobile Tank Cleaning Systems are classified by the system’s capability to treat a single tank in eight hours. It is recommended that you treat each tank when it is full (why clean only the bottom half of the tank?), and the entire contents of the fuel storage tank should be circulated three times to achieve the diesel fuel cleanliness rating recommended by engine manufacturers. (Note: the first time a tank that has been in use for more than five years is cleaned, you should circulate the contents five times, and then three times each cleaning thereafter as determined by your Fuel Management Plan (see below), part of a preventative maintenance program.

Based on the range of tank sizes that you will likely be treating, choosing the right Mobile Tank Cleaning System for your application is a function of the amount of time (man-hours) you can dedicate to each tank cleaning. Ensuring low ongoing costs is critical, as is efficient use of personnel. As an example, let’s assume you have numerous tanks in the 10,000 to 20,000 gallon range, and two or three that are 30,000 to 40,000 gallons. An MTC HC-150, operating at 150 gallons per minute (9,000 gallons per hour) can perform a complete treatment of 30,000 gallons (a 10,000 gallon tank circulated three times) in 3.3 hours. This allows for the cleaning of two (2) 10,000 gallon tanks in one day, with 1.4 hours of an 8 hour workday for mobilizing to the tank, setup, treatment, packing up the equipment and transit back to the base location. Sevicing a 25,000 gallon tank would require 8.3 hours. Servicing larger tanks will require a two day treatment schedule. This necessity may be unacceptable if more than a few tanks required more than one day, but with only a few such situations, this would be considered an efficient operation. The MTC HC-150 also provides the flexibility of servicing numberous 1,000 or 5,000 gallon tanks with this same equipment.

Dual Port Valve

In the process of cleaning fuel tanks, most operators will affix a rigid pipe (often a length of PVC pipe) onto the end of the suction hose to allow for moving the suction inlet along the tank bottom to suction the areas where sludge accumulates, commonly the low point of the tank. This is difficult with the larger hose of the MTC HC-150. Available as an option, the Dual Inlet Port allows for connecting a one inch hose to the regular suction of the MTC HC-150, and while the MTC HC-150 is running, circulating the fuel, the operator may use a second one inch hose and suction pipe to easily pin-point suction to specific areas of the tank bottom.

Smaller storage tanks tend to have smaller access ports, precluding the use of higher flow Mobile Tank Cleaning Systems that utilize larger diameter hoses for suction and return lines. As an example, if you will be cleaning tanks that have a three inch filler cap as the only access, the maximum house outside diameter would be one and one-half inches (1 1/2 inch) for each hose. Check tanks for anti-siphon devices as these may prevent access for tank cleaning purposes. If you have only a few small tanks, but otherwise require a high flow system, consider tank modifications that provide a larger access port.

MTC HC-150 Functionality

Because of the variability of flow with the MTC HC-150, it can utilize a low pump rate and, using Discharge Port 1, the HC-150 will easily remove sludge and water from the bottom of your tank without creating a "Milk Shake Effect" by mixing fuel, water and sludge. Discharge Port 1 can also be used to transfer fuel to another tank while processing it through the Primary and Secondary filter.

Processing fuel through the Primary Filter, Secondary Fuel Filter/Water Separator and Purifier, AXI Fuel Conditioner, and Tertiary Filter and back to the tank through Discharge Port 2 reconditions the fuel and cleans tanks quickly and efficiently with a high flow rate. Returning the fuel back to the tank from Discharge Port 2 after the Tertiary Filter completes the fuel dialysis and reconditioning process. Depending on the job, AXI offers a choice of filter bags for the Primary filter and a variety of fine filters, coalescing filters and water block elements for the Tertiary filter.

The MTC HC-150 System processes fuel or oil by pumping it from the tank through the intake hose to the intake port, through the Primary Bag Filter, and then to the Secondary Centrifugal Fuel-Water Separator and Purifier. Flow may then be directed to exit the system by Discharge Port 1 or may be directed to the AXI Fuel Conditioner, then to the Tertiary Fine Filter which may be equipped with a variety of filter elements that are dependent upon the conditions being addressed in the treatment, and then exit the system through Discharge Port Two and back to the tank.

Directing flow to exit at Discharge Port 1 is typically done during the first two phases of the circulation system allowing the Primary and Secondary filter, using inexpensive bag elements, to remove the coarse debris and sludge. Using Discharge Port 2 is typically done in the later stages of the Fuel Polishing process to gain fine filtration and removal of emulsified water with coalescing filter elements which are more expensive, but allow for the fuel cleanliness to reach a level consistent with established fuel cleanliness standards required by diesel engine manufacturers.

AXI Fuel Conditioner

The MTC HC-150 Tank Cleaning System utilizes two AXI Fuel Conditioner situated in parallel after the fuel flow exits the dual Primary and Secondary Filtration vessels. Operating on the principal of induction on the process of combining kinetic and magnetic energy to influence the behavior of electrons, the AXI Fuel Conditioner provides a powerful magnetic field and the flow of fuel provides the kinetic energy.

As fuel deteriorates, clusters of fuel components break down and residue begins to accumulate, resulting in dark, hazy fuel with poor combustibility. The increase in size and mass of the fuel breakdown products lead to clogged filters and the build up of tank sludge. The AXI Fuel Conditioner dissolves the clusters, stabilizes the fuel, and eliminates tank sludge. The results are Clear & Bright Fuel, improved filterability, optimal combustion and clean fuel systems. The process of how the AXI Fuel Conditioner makes clear, bright and more combustible fuel as well as restoring degraded fuel and eliminating the effects of microbial contamination is compelling. As the AXI Fuel Conditioner does not filter the fuel, but treats it as it passes through the unit, there is seldom any reason to suspect that a restriction is in the AXI Fuel Conditioner. But you can remove the face plate, remove the magnet and wipe it off with a shop rag and replace the filter and face plate. A spare parts kit for the AXI Fuel Conditioner includes a new face panel O-Ring and replacement screws to fasten the face plate.

Primary Filtration for the MTC HC-150 System

The MTC HC-150 Tank Cleaning System utilizes two PF-30 HD Bag Filter Vessel situated in parallel as the Primary Filtration. The PF-30 HD Bag Filter Vessel uses felt or multi-filament mesh filter bags to remove heavy particulate and sludge from 800 micron down to 1 micron, and a perforated, stainless steel strainer is also included. The bags are inexpensive compared to spin-on filter elements and are, to a limited extent, re-usable, further reducing the expense of doing fuel maintenance by reducing the cost of disposable supplies. On tanks that require removal of considerable sludge and debris, the PF-30 HD may be used with only the stainless steel strainer (no bag element) until much of the coarse debris has been removed with the strainer.

A Water Sight gauge is installed on the front of the PF-30 HD Bag Filter Vessel to observe the level of water accumulation within the Bag Filter vessel. Monitor the gauge and drain the water as often as needed using the drain valve on the bottom of the Bag Filter vessel.

PF-30 Bag Filter

Two vacuum gauges are provided on the front of the Primary Filter Bag Vessel. The top gauge provides a reading on the suction line into the filter, and the lower gauge provides a reading on the inside of the bag, allowing you to use the differential gauge reading to determine when the bag requires operator attention.

An optional water sensor and alert module may be added to the FP Water Separator-Purifier that utilizes a 9 volt powered audible and visual alarm to advise when the FP Series unit requires draining.

Secondary Filtration for the MTC HC-150 System

The MTC HC-150 utilizes two AXI FP-90 Water / Separator Purifier situated in parallel as the Secondary Filtration. The FP-90 utilizes the principle of centrifugal force to split water, fuel sludge, and particles of dirt from fuels, and separate them so that the waste can be isolated and drained out without the use of filter elements that must be purchased, inventories and consumed. The heavier fluid (water), sludge and particulates are heavier than diesel fuel (water, sludge and particulates have a specific gravity greater than diesel fuel). When spun around inside the cylinder, guided by baffles inside the cylinder, these materials are forced to the outside wall of the cylinder and then drops down along the outside wall of the cylinder to collect at the bottom of the cylinder for removal by opening a valve and depositing these contaminants into a container for proper disposal.

FP-90 Fuel Water Separator and Purifier

Any free water or sludge that may pass through the Primary Filter will be caught in this Secondary Filter. When a tank being cleaned is especially contaminated, use the stainless steel screen/basket in the Primary Filter without a bag filter element and allow the FP-90 to remove the sludge and free water without incurring the cost of filter bags. The amount of solids and sludge being suctioned from the bottom of the tank being cleaned will be evident in the clear suction hose. When you can no longer see the solids and clumps of debris in the suction hose, stop the system and insert a coarse filter bag in the primary filter and begin again to circulate fuel. As more debris is being filtered with the Primary Filter, periodically change the bag to a finer micron rating. As you work your way down to a 10 micron bag, change the discharge hose to Discharge Port No. 2 so that the circulation passes through the Fuel Conditioner and the Tertiary Filter.

Tertiary Filtration for the MTC HC-150 System

The MTC HC-50 utilizes two FV-120 Series High Flow Filtration Housings, situated in parallel, to perform the fine filtration after relocating the discharge hose from the Port 1 Discharge Port to the Port 2 Discharge Port.

FV-120 Tertiary Filter

Each FV-120 Filtration vessel utilizes one (1) 6 inch by 18 inch filter element that is capable of filtration with a Cellulose Particulate Removal element in 2, 10, or 30-micron rating, or a Cellulose Particulate and Water Block element in 3, 7 or 10-micron rating, or a Micro-glass High Performance Particulate Removal element in 3, 7, or 10 micron rating.

Hoses for the MTC HC-150 System

The MTC HC-150 System includes 25 feet of three inch clear suction hose and 25 feet of 2 1/2 inch discharge hose, each including Cam & Groove fittings (with dust caps) for connection to the ports provided on the MTC HC-150 with Cam & Groove connections. Additional hose may be purchased when ordering with an additional charge per foot of hose as set forth in the hose pricing on the right.

Sample the Tank Bottom

If a tank has a straight-line access to the bottom of the fuel tank from the fuel fill hole or through another inspection port, a length of PVC or similar material pipe, 1/2 inch in diameter, can be used like a soda straw to sample what is in the bottom of a tank. Cut the pipe to length to allow insertion of the pipe to the bottom of the tank while allowing your thumb to cover the exposed end of the pipe. With your thumb over the end, insert the pipe to the bottom of the tank, remove your thumb so what is at the very bottom will rush into the tube to the level of fuel in the tank. Again place your thumb over the end of the pipe and extract the pipe, maintaining the liquid and other materials inside the tube. Place an empty clear plastic 2 liter soft drink bottle upright in the bottom of a empty 5-gallon bucket. Direct the end of the tube into the drink bottle (any spilled liquid will be caught inside the five gallon bucket). Perform this action several times. Allow the contents of the bottle to settle (ideally overnight) and inspect the materials in the bottom of the drink bottle. Any debris or water should be apparent.

If your tank is larger and using a tube to recover fuel, water or other debris from the bottom of the tank is not possible, you can use a Tank Sample (TS) Fluid Sampler. You can take 4 oz., 8 oz, or 16 oz. samples using the AXI Tank Sampler or you can use a hand-held Sample Pump (at bottom of the AXI Tank Sampler page) to remove a sample, as described on the Tank Sampler page.

General Tank Cleaning Procedures

The MTC has two different operating modes (Bypass Mode and Fine Filtration Mode), providing the operator flexibility and time efficiency.

In Bypass Mode, bulk water and sludge are removed from the tank into a separate container for disposal. The fuel bypasses the fine filters, removing free water, sludge, and particulate, as small as 1 micron, from the tank. During this step, the system is not in a re-circulating mode. The fuel enters through the Inlet Port and exits through Discharge Port 1 into a separate waste container. Water and sludge are directly removed from the tank and collected in an appropriate container for disposal. Next step, while still in bypass mode, put the hose that was in a separate container back into the main ank to create a kidney loop. This process will further save and extend the life of the spin-on filters, and remove the worst of contaminants, before polishing with fine filters to meet the required cleanliness.

In Fine Filtration Mode, the MTC system is continuously restoring, reconditioning, and returning the fuel back to the tank. Fine Filtration mode will continuously remove free water and particles as small as 1 micron, utilizing high efficiency spin-on filters.

We always recommend keeping a “before” and “after” bottom tank sample for "show & tell" purposes to demonstrate the improvement of fuel color, clarity, and opacity.

System Operation

Operating Procedure

Hoses: The intake/suction hose is a clear, see-through reinforced vacuum hose. The return hose is black or blue/black, non-marking, high quality, discharge fuel hose. Both hoses are equipped with quick disconnects or Cam & Groove couplings.

  1. Attach quick disconnect end of clear suction hose to the quick disconnect Inlet Port of the MTC.
  2. We highly recommend attaching a straight wand or pipe (cut at an angle at the end that goes into the tank and is at minimum the same inner diameter as the suction hose) to the suction hose to reach the lowest part of the tank bottom.
  3. Attach quick disconnect end of blue/black discharge hose to quick disconnect Discharge Port 1 of MTC.
  4. Place the end of the discharge hose in an appropriate-size container (Phase One only). Try to not agitate the fuel in the tank and stir up and disperse water and sediment throughout the fuel –- this will make it more difficult to remove later on.
  5. For Phases Two and Three, place the end of the discharge hose back in the tank as far away as possible from the suction hose. Ensure that the hose is secured and will not vibrate out of the container when the system is operating.
  6. Verify that both drain valves are closed and the system is set up in a stable and safe position.

Note: Never restrict the flow on the suction side of an MTC; e.g. by using a smaller ID hose or pipe or attaching the suction hose to a fitting on the tank that has a smaller ID than the hose. This will lead to excessive pump load, noise and ultimately damage the pump.

Phase 1:

AXI recommends 3 phases to successfully polish a fuel tank. This will ensure all water is removed from the fuel, particulate is removed, and the fuel is in an optimal condition. The goal of Phase One is to remove any free water and sludge on the bottom of the tank without mixing the water into an emulsified state within the fuel.Start the pump motor and be ready to immediately stop it. The vane pump will start pumping as long as the system is primed and the suction lift is not excessive. The flow of fuel can be observed in the see-through suction hose. Watch for a steady flow of fuel into the container.

  1. Once the fluid begins to fill the discharge container, immediately switch off the motor and inspect the discharged fluid. Resume pumping and continue the above procedure until water and sludge have been removed from tank bottom and primarily fuel is discharged from the return hose.
  2. To remove as much of the free water and sludge as possible, the suction hose with a straight wand or pipe attached should be placed at the deepest part of the tank. If possible, move the suction hose/pipe to different areas of the tank to more efficiently vacuum the sludge off the bottom. After removing the bulk water and sludge from the tank, switch off the pump. Then, drain all water and debris from the hose and the water separator into an appropriate bucket placed under the drain valve.

Phase 2:

After removing the bulk of the sludge and water from the tank into a separate container for disposal and draining the separator, the return hose is now inserted into the tank. The goal of Phase Two is to remove any additional free water within the tank and also remove any large contaminants and sludge. This phase will clean the fuel and should be a precursor to using the more expensive spin-on filters. It should be noted that meeting required cleanliness codes is typically not possible with pre-filtering alone. Phase Two is used to extend the life of the spin-on filters, and remove the worst of the contaminants, before polishing with fine filters to meet the required cleanliness.

  1. Insert blue/black discharge hose into tank as far away from the suction hose as possible. In some cases, it is recommended to remove the sending unit cover to gain sufficient access to the tank. In many cases, both hoses will have to be inserted through the same tank fill opening.
  2. After verifying that both hoses are properly placed in the fuel tank and that the valves on the MTC system are in the correct position, switch on the pump and watch the clear suction hose for fuel flow.

Depending on the amount of contaminant in the tank, we recommend you stop the pump shortly after priming and check for free water and sludge by draining the water separator. It may be necessary to depress the air purge valve on top of the separator after opening the drain valve.

Repeating this process and observing the fuel flow will indicate how long the pump should run before it is necessary to drain the separator.

  1. The MTC should be kept running in the Phase Two recirculating mode until clean fuel samples can be drained from the separator. Then, switch off the pump for final polishing.
  2. Now is the time to add AXI International AFC-705 Fuel Catalyst in a dose of 1 : 2500 or 1 gal of AFC-7010 for 2500 gallons of fuel. Higher doses of AFC-705 may be necessary depending on condition of fuel.

Phase 3:

Phase Three is the most important phase in meeting specific cleanliness codes. Unlike the pre-filter, the spin-on filters typically use absolute rated media. Absolute filters have a very high efficiency and will ensure that fuel leaving the system is clean to specification and has a low water content. Like previously mentioned, pre-filtering should be performed to remove any large particulate, water, and sludge. Pre-filtering will extend the life of the spin-on filters.

  1. Connect the return hose to Discharge Port 2.
  2. Start the pump and the system will run in the re-circulating mode restoring the fuel to its optimal pristine and sparkling condition.
  3. Monitor the pressure gauge on the filter head. When the pressure reaches 20 - 25 PSI, or reaches the red area it is time to change the filter.

Recommended Tank Cleaning & Fuel Treatments

AFC-705 Diesel Fuel Additive

It is recommended that diesel fuel be treated with the AXI Fuel Catalyst AFC-705 (for pre-2007 engines) or AFC-710 (Tier 4 compliant) Diesel Fuel Catalyst prior to the initial tank cleaning and at least every six months thereafter to assure the fuel tank remains clean and the fuel is stabilized. This will enhance and accelerate the tank cleaning process by breaking down and dissolving existing tank sludge. Always check the fuel tank for an accumulation of water in the bottom of the tank. Using a rod, sometimes used to measure fuel in a storage tank, or a length of PVC pipe, spread a line of Kolor Kut Water Finding Paste on the side of the rod or pipe and insert to the bottom of the tank. If the paste touches water, it will change colors, showing how much water is in the tank requiring removal.

AFC-710 Diesel Fuel Additive

Pump accumulated water out of the tank for proper disposal. It is often the case that all of the water is impossible to remove. AFC-705 contains a surfactant that will emulsify the residual water up into the fuel for removal by a Water Block Filter on the AXI Fuel Polishing System AFC-710 does not include this surfactant component). Depending on the condition of the fuel and the amount of sludge build-up, it is recommended to initially use a double dose of one to twenty-five hundred (1:2500 - one oz. to 20 gallons of fuel) and circulate the capacity of the tank five times. Always treat the tank when the tank is full of fuel. If you perform a treatment with a half tank of fuel, you will only be cleaning the bottom half of the tank. The use of AXI Fuel Catalyst has proven to be essential in accelerating the tank cleaning process. AFC-705 and 710 contains detergent, dispersant, corrosion inhibitor, lubricity enhancer and combustion catalyst. AXI Additives do not contain biocides.

AFC-710 Powder Diesel Fuel Additive

For engines manufactured in 2007 and later, use AFC-710, available in both liquid and powdered form. AFC-710 does not contain the surfactant (used to emulsify residual water into the fuel for removal in the circulation process as does AFC-705), a component that does not allow for qualification as a Tier 4 product. AFC-705 and AFC-710 should always be used periodically in particular to stabilize fuel that is stored for longer periods of time.

After the initial cleaning, the AFC-705 or AFC-710 in the fuel will continue to stabilize the fuel for six months or more. Every six months, or more often if the region in which you reside is a humid climate, treat the fuel again and circulate the capacity of the tank three times. In applications where fuel from a treated tank is distributed to other equipment, the additive will also clean the downstream tanks and continue to stabilize the fuel.

Tank Cleaning & Fuel Treatment for Cold Weather Use

For cold weather operations, AXI Fuel Catalyst AFC-805 is a unique and powerful anti-gelling broad-spectrum fuel additive specifically formulated for use in Diesel, Bio-fuels, Gasoline, Kerosene, and HFO. AFC-805 should be used as part of any preventative fuel maintenance program, and is ideal for use in bulk storage fuel tanks in cold weather environments. AFC-805 enhances the breakdown and removal of sludge, slime, and bio-fouling from tank walls and baffles that are difficult to access.

AFC-805 effectively decontaminates and cleans an engine’s entire fuel and injection system. It continues to work in storage tanks cleaning and stabilizing fuel for up to 12 months with a single dose. AFC-805 is ideally used for cold weather applications where there is long term fuel storage, such as bulk fuel farms, winterized recreational and work boats, and also smaller engines. AFC-805 is recommended at a ratio of 1:5000 (one oz of AFC-805 to 40 gallons of fuel)

Fuel Management System Operation

The fuel you depend on should always be in optimal condition. Periodic circulation of fuel assures optimal combustibility and fuel cleanliness. All major diesel engine manufacturers have set minimum fuel standards for the diesel fuel to be used in their engines, and failing to maintain fuel that meets those standards could lead to engine component failures and denied warranty claims. As an example, Caterpillar has published "Cat Commercial Diesel Engine Fluids Recommendations" (SEBU6251-17 September 2014 [a more recent version may be available]) that states "In order to meet expected fuel system component life, 4 micron(c) absolute or less secondary fuel filtration is required for all Cat diesel engines that are equipped with common-rail fuel systems." (Page 34) You should not assume that fuel being delivered to you meets the engine manufacturer’s requirements, and certainly fuel that has been in your storage tank for an extended period of time is unlikely to meet requirements of diesel engine manufacturers without a Fuel Management Program.

Cleanliness standards for diesel fuel, established in the late 1990’s by the International Organization for Standardization (ISO), apply to diesel fuel. Caterpillar recommends that the fuel dispensed into the machine tank meets "ISO 18/16/13" cleanliness level." (Page 49) For more information on fuel cleanliness specifications and what those requirements mean to you, review the "Diesel Fuel & Injector Failure" web page on this site.

Continued vigilance to assure that your fuel is in the best condition possible and always meets the requirements to maintain engine manufacturer's warranty requirements is a major challenge without the use of an AXI Fuel Conditioning & Tank Cleaning System to address the need for periodic Fuel Polishing.

Fuel Maintenance Plans

Clogged Fuel Filter

A Fuel Maintenance Plan should be a part of every periodic engine Preventative Maintenance Program. Preventative Maintenance Programs are common in all major industries today, but monitoring the fuel condition is often taken for granted and not included in the Preventative Maintenance Program. Many of today's maintenance personnel have many years of experience, but until changes in sulfur content in diesel fuel were regulated within the past decade, and with the government’s push for blending some amount of bio-diesel into regular diesel fuel, maintenance professionals were never presented with the problems that we are experiencing today. With today’s advances in design and engineering of diesel engines, especially the new fuel injection systems, and with more emphasis being placed on critical requirements that equipment have longer life cycles and near 100% uptime, fuel management can no longer be ignored. It is now just as important as changing the oil, ensuring the batteries are charged, and the air filter is clean.

Service Agreements with an outside contract company to perform Preventative Maintenance typically do not cover fuel-related management and monitoring unless specified. In-house maintenance personnel are usually pressed for time, and fuel management can be easily glossed over. Fuel has a limited shelf-life and even "fresh fuel" could contain water, sediment, microbes, asphaltene agglomeration, or other contaminate components upon delivery and cause immediate engine performance issues.

Emergency power installations are especially susceptible to unexpected interruptions due to fuel related issues. Periodic generator tests-runs are too short to determine if fuel quality is adequate for the demands of continuous, full-load operation. In fact, generator test runs have been found to significantly accelerate the fuel polymerization and degradation process, resulting in the accumulation of gums and resins in the fuel system, by returning fuel that has been compromised by heat and pressure back to the tank. Thirty minute tests, often performed every month, create the environment in the tank for problems to grow. After extended periods of testing, sometimes years, without having been subjected to an extended full load, operation is interrupted by clogged filters when the lights go out.

Now that you have decided to institute a Fuel Management Plan for your operations, there is work to do. Consider the following as the basis for your Fuel Management Program to further assure that your equipment will run when it is needed most at it’s peak level of performance and repair costs will remain under control:

  • Place in service an AXI Fuel Treatment & Tank Cleaning System appropriate to your operations that are capable of performing a complete tank cleaning and fuel conditioning on each fuel tank in service at least once per year (more often in regions of high humidity). Evaluate what other aspects of fuel monitoring and testing is needed to assure that critical equipment needs, including down-stream equipment, may need to be included in your Fuel Management Plan.

  • Use AXI Broad Spectrum Fuel Catalyst Ultra Concentrate AFC-705 or AFC-710 every six months to enhance the breakdown and removal of sludge, slime, gums, resin, and bio-film from tank walls and baffles that are difficult to access and normal fluid flow does not break loose. Having this unique fuel additive present when fueling downstream equipment also assures that these downstream tanks are being cleaned in the normal course of operations (although separate water removal will be necessary).

  • Periodically (every 30 to 60 days, depending on your climate) use a Fluid Sampler or a hand Fuel Sample Pump to take samples of your fuel from each storage tank and critical equipment fuel tanks for in-house testing for acidity (pH) and use Liqui-Cult Fuel Test Kits to perform testing for microbial contamination. If initial tests indicate fuel problems, utilize laboratory analysis to evaluate the condition of your fuel to assure your fuel supplier is providing fuel that meets the specification of the engine manufacturer you depend on to keep your equipment running.

  • If the quality of your fuel is suspect, consider establishing a quarantine tank to accept new shipments (do not add new shipments of fuel to your stored fuel that has been de-watered and to which you have performed fuel polishing, and is known to meet your Fuel Management protocols).

  • Use Kolor Kut Water Finding Paste at least every 30 to 60-days to monitor the accumulation of water in your storage and equipment fuel tanks due to condensation or from fuel fills. If any amount of water is detected, take steps to remove it.

  • Install Desiccant Breathers on all your fuel storage tanks to help prevent moisture from entering your tanks through the vent as fuel is consumed.

  • Use Water Eliminators in each storage and equipment fuel tank to capture water and remove it before it can cause problems with engine operations or seasonally prevent water from freezing in fuel lines?

With only moderate effort, you can be assured that your diesel fuel will provide optimal performance and enjoy the expected life of your engine’s fuel filters, fuel system components, and your substantial investment in the diesel engine.
