When the Lights Go out ... it is Too Late to Clean Your Tanks.

It is the condition of the fuel in your tanks that determines Engine Performance and Emergency Power Reliability.

Fuel is inherently unstable. It naturally forms sediments, solids and tank sludge. Clogged filters, excessive exhaust smoke, loss of power, and premature damage or failure of fuel injection systems are often symptoms of less than optimal fuel quality causing engines to be unreliable and ultimately fail. Water naturally accumulates in storage tanks due to condensation or leaks in fills and vents. Water and temperature changes create an environment for microbial growth and natural oxidation, accelerating formation of sludge, acids and tank corrosion.

Today's diesel injection systems with pressures of 30,000 psi or more require that the particle size of your fuel does not exceed the tolerances of your engine. Primary filter water-separators dramatically improve engine protection. However, they can only do so much.

In the industry, terms like algae, gum, wax, resin, varnish, tar, asphaltene, etc. are often used to describe the organic contaminant that clogs filters and is responsible for cargo deposits, corrosion, failing injection systems, loss of power, incomplete combustion (black exhaust smoke), and excessive emissions.

A program established to assure continuous optimal fuel quality will reduce overall operating costs

Most Engine Performance Problems
Start in The Fuel Tank

Over the last number of years we have seen a sudden, dramatic and worldwide increase in Filter Plugging Tendencies. What has changed? Oil supply and environmental concerns have resulted in important changes in fuel production, such as cracking, blending, ultra low sulfur, and the introduction of bio-fuels.

These changes have negatively impacted the inherent instability of our fuel and significantly shortened its shelf life. Additives, storage and transportation challenges further accelerate fuel degradation.

Fuel degradation is an inevitable, natural process. And unless an adequate fuel sampling, testing, monitoring and maintenance program is implemented, fuel breakdown will continue to be a potentially expensive liability and a major contributor to your overall operating costs.

Diesel is a very complex fluid. It is not homogenous and no two batches will ever be identical. Fuel deterioration, filterability and shelf life depend on a variety of factors including good housekeeping.

Reliable Power requires the implementation of a unique and innovative Fuel Optimization and Maintenance Technology to adequately protect engines and preserve the integrity of stored fuel beyond filtration and separation.

The STS 6030 Fuel Filtration Systems are self contained, stand-alone and fully automated. They recondition and stabilize fuel, eliminate & prevent microbial contamination and remove water, sludge and contaminants from tanks; preserving the integrity of stored fuel, providing reliable power whenever it is needed.

Implementing STS Fuel Maintenance Systems assures Optimal Fuel Quality & Reliable Engine Performance at all times. It prevents costly downtime, periodic tank cleaning, replacing out of spec fuel and injection system repairs.

The principal STS-6030 30 GPM components are a Nexus Y-Strainer to protect the pump, continuous duty motor with coupled gear pump and Viton Seals, Primary filter to remove debris, Secondary coalescing filter to dry the fuel, and Algae-X Fuel Conditioner to optimize fuel quality, increase filterability and eliminate microbial contamination.

Both primary and secondary filters are equipped with pressure gauges, water sensors and alarm modules. The programmable UL 508A listed AXI Smart Filtration Controller automatically operates and monitors the STS system. All components and control devices are contained within a fully enclosed, lockable, weatherproof, NEMA certified enclosure.

For safe operation the STS 6030 is equipped with alarm indicator and system shutdown when filters need service. Additional safety elements include automatic system shut-down and leak detection, water detection in the filter, high pump vacuum, high pump pressure, low fuel flow alert or a flow interruption is detected and flow meter with " no flow " alarm indicator and system shutdown (pressure transmitter).

The Smart Filtration Controller also provides a maintenance alert log file, runtime totalizer, alarm history and on-screen help.

All STS Systems feature multi-stage water removal and particulate filtration, NEMA 12, 13, 3R, 4 Powder Coated or Stainless Steel enclosure, UL508a Smart Filtration Controller and stainless steel plumbing, and is available power for 120 Volt / 60 Hz (15 Amp) or 230 Volt / 50 Hz (15 Amp), and other voltages are available.

Optional equipment may be ordered. An automatic water drain system is available, and a unistrut pedestal stand is available for mounting the enclosure up off the floor (standard is for wall mounting) and although the standard STS System is configured for use will one tank, optional configurations allows for use with two, three or four separate tanks. Other colors are also available.

A System that will Assure Your Equipment Runs at Peak Efficiency with Optimal Performance

The STS 6030 Automated Fuel Maintenance System suctions fuel from your storage tank at 1,800 Gallons per Hour and may be specified for use on up to four separate fuel tanks. Ideally, fuel should be suctioned from the very bottom of the tank, and also from a low point in the tank, or even a tank sump, where water would normally accumulate. Fuel passes through a Magnetic Y-Strainer that removes any particulate or other item that may damage the fuel pump. A pot on the Y-Strainer is used for the vacuum switch. After passing through the Internal Gear Pump, a pressure switch is positioned to sense any downstream resistance to flow. Any resistance would indicate a clogged filter or other obstruction int he line. The fuel then flows through the inline AXI Fuel Conditioner and on to the primary filter. A Racor FBO-14 Primary filter is used with Particulate Elements that filter 25, 10, 5, or 1 micron, and then continues to a second Racor FBO-14 Secondary filter equipped with a 25, 10, 5, or 1 micron Coalescing Filter Element. Each Racor FBO-14 has its own pressure gauge to visually determine when a filter element is becoming clogged and in need of replacement. Elements are easily replaced by hand loosening four collar bolts, and then rotate and lower the bowl assembly for element change outs. With new element installed, simply raise the bowl and rotate into position on the locking ring and hand tighten evenly. Each FBO-14 also has drain valves for removing water from the filter vessel.

The optional Automatic Water Drain provides automatic water removal from the Primary Filter/water separator. Three Watect Water Level Sensors control the water drain pump and also provide emergency system shutdown in the event of a component default. An inline strainer is incorporated to protect the water removal pump. A 30-gallon waste water drum with removable lid and EPDM gasket is included. The drum is made of translucent 3/16" polyethylene to show the level of waste water in the drum. A water level float switch is installed in the drum to assure the waste water drum does not over-fill.

The WATECT Water Sensor is monitored by the Controller and will provide an alert when the water level is too high. An Automatic Water Drain is available as an option to automatically discharge the accumulated water from the Primary Filter bowl into a holding container for later disposal.

The optional Automatic Water Drain Option provides automatic water removal from the Primary Filter/water separator. Three Watect Water Level Sensors control the water drain pump and also provide emergency system shutdown in the event of a component default. An inline strainer is incorporated to protect the water removal pump. A 30-gallon waste water drum with removable lid and EPDM gasket is included. The drum is made of translucent 3/16" polyethylene to show the level of waste water in the drum. A water level float switch is installed in the drum to assure the waste water drum does not over-fill.

A Vacuum Gauge is provided on the top lid of the Separ Fuel Filter/Water Separator to allow for visual monitoring of Vacuum. When the Vacuum reading increases, indicating that the replaceable filter element has reached its capacity for holding particulate material, you know the filter needs changing. No more guessing or changing the filter too soon.

The clean fuel leaves the filter via the outlet port and passes through the Vacuum Switch connected to the Controller, constantly monitoring vacuum and, upon detection of high vacuum, caused by a clogged Primary Filter or obstruction in the suction line, the Controller will send an alert that high vacuum is occurring, and likely the filter needs replacement. The fuel then continues to the suction size of the Internal Gear Pump. Fuel then exits the pressure port of the pump and passes through a Pressure Switch with Gauge that allows for both visual reading of the pressure in the discharge side of the pump and monitoring of the discharge pressure by the Controller. If discharge pressure is too high, an alert shut down the system. This typically indicates a clogged secondary filter or obstruction in the discharge pipe.

The fuel flow continues to the AXI Fuel Conditioner. 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 int he 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.

The fuel then continues to a double Secondary Filtration stage. The first Secondary Filter would typically be a ten micron or three micron rated Water Block Filter spin-on element, designed to remove entrained and emulsified water from the fuel stream. The second Secondary Filter would typically be a 10, 3, or 1 micron particulate filter element. A pressure gauge is provided on the Secondary Filter housing to allow for visual monitoring to determine when filter elements require replacement, and a Pressure Switch is provided downstream from the Secondary Filter housing for monitoring by the controller. A restricted Secondary Filter would result in an alert from the Controller of low pressure. Low fuel flow may also cause an alert. Ball valves are provided at the inlet port and outlet port to allow for shutting off fuel flow in the event fuel flows back into the cabinet when filters are being replaced.

Fuel is then directed back into the storage tank. Ideally, the return line should be at the opposite end of the tank from the suction pipe pickup so that the agitation of the fuel will move water and particulates towards the suction line.

Leak Detection by way of a float switch in the bottom of the cabinet should the unexpected happen and fuel collects in the sump in the cabinet. Upon detection, the Controller will shut down the system.

An Enclosure Heater is available as an option for exterior mounting of the STS 6010 Automated Fuel Maintenance System outdoors in cold climates to protect the electronic components inside the enclosure. In cold climates, separate steps should be taken to assure the fuel temperature does not drop below 40 deg. F (5 deg. C) which may result in crystal formation in the fuel thereby clogging filters.
