Portable and Mobile Fuel Conditioning
and Tank Cleaning Systems

Mobility Gives You Flexibility
When You Have Many Tanks or Many Locations

In any application where diesel powered engines provide the horsepower to get the job done, the horsepower must be ready to run on call and for the duration of the critical times. The diesel-powered engines used in equipment may sit without operation for long periods of time until that horsepower is needed to perform. They may also be widely dispersed in numerous unique equipment or across diverse locations throughout a wide region. To ensure these engines and generator components operate at optimum efficiency when called upon, AXI® (formerly Algae-X) has developed Automated Fuel Conditioning and Tank Cleaning Systems capable of servicing these wide ranging fuel storage tanks and diverse locations efficiently, economically, and quickly.

The following list provides basic characteristics of the AXI Portable and Mobile Fuel Conditioning and Tank Cleaning Systems (otherwise known as Diesel Fuel Polishing) to allow for your initial identification of a system that may meet your needs. Power supply and flow capability (relates to fuel tank size) is the most critical for your initial consideration, but where you are going to use the system (in an equipment service facility, in the field where the equipment is at work, at diverse facility installations, or in the equipment yard) is also important. The larger systems provide fast treatment cycles, but are not necessarily adaptable to smaller tanks. Smaller systems can service a wide range of tank sizes by just running them longer, but requires servicing personnel to be attentive to the process, and the labor costs can be a significant consideration in maintaining cost effective operations.

Do not be overly concerned about the flow capacity of the system as compared to the size of tank or tanks that you are managing. A lower flow rate simply means the system must operate for a longer cycle to perform the periodic tank maintenance. Of course, a system that is so small that it must operate constantly will, itself, require more maintenance. A rule of thumb is a tank should be circulated three times under a preventative maintenance program, and the treatment should be completed in less than 50 operating hours (not necessarily continuous).

Do consider the means necessary to suction the fuel from the tank and returning the treated fuel to the tank. Tanks that are to be regularly treated may be fitted with fittings allowing quick connection of hoses or inspection ports to allow for ease of access, but sometimes access is only achieved by placing suction and discharge hoses in the same fuel filler opening, and larger circulation systems, having larger diameter hoses, negating their use in smaller tanks.

How often your Fuel Conditioning and Tank Maintenance System operates will depend on a number of factors. Fuel that is stored for an emergency may need to be circulated three times once each year in certain climates and conditions. Areas with more humidity and temperature variances would require more frequent treatments. Where fuel is used more often and new fuel is taken on regularly, treatments may need to be performed whenever new fuel is taken on, circulating the entire tank. If a quarantine tank is used (one where all new fuel taken on is placed), only the new fuel would require treatment and, upon completion, transferred into the more permanent storage tank.

System Integration

Larger systems (those mounted on one or more pallets) are equipped with an automatic controller system. Systems are designed to run automatically at predetermined times to treat the fuel and filter water, sludge and tank sediment from fuel storage tanks. The automation system provides extensive control and notification functions to advise the operator with the status of the systems operations.

Smaller systems (hand-held or cart mounted systems) are more mobile and have manual on-off operation and gauges that monitor filter life, although audible and visual alarms are available as an option for alerting the operator to the need to drain water captured in the fuel-water separator.

Portable and Mobile Fuel Conditioning and Tank Maintenance Systems are categorized based on how much fuel can pass through the system in eight hours. A typical preventative maintenance treatment requires three cycles of a full tank of fuel to treat 90+% of the fuel in a tank. As a result, an MTC 1000 LX system can treat a tank up to 2,400 gallons (9,000 liters) in an eight hour period. However, if a second eight-hour period is added, then the system can treat a tank up to 4,800 gallons, etc. An eight-hour period is used as a measure of one work day as the portable and mobile Tank Cleaning Systems must be attended, unlike the Automated Fuel Treatment Systems that are equipped with advanced controllers and automatic shut down capabilities in the event of an alert.

Mobil Tank Cleaning Bag Filter Systems

Designed as a cart-mounted two-stage Bag Filter equipped Mobil Tank Cleaning (MTC) System to decontaminate fuels, oils and hydraulic fluids. The MTC-X units efficiently remove water, sludge and sediments that naturally accumulate in tanks. With the optional AXI® Fuel Conditioner, the circulation system eliminates fuel instability and sludge buildup. The MTC-X Bag Filter System is ideal for the type of application where the operator never knows how bad the fuel in the tank is or how far it has degraded. Using filter bags, filtration can start with an 800 course filtration bag, removing the heaviest sludge and debris without going through a lot of expensive disposable filter elements, while removing the worst of the water in one easy step. When the worst of the contaminants are removed, adjust the process by turning a valve to filter with fine particulate filter elements and filter elements that will remove the finer contaminants and water (Water Block Elements). The AXI® MTC-X unit, is designed for commercial or industrial applications that require serious service on mining equipment, construction equipment, marine equipment, train locomotives, and diverse, hardworking generator and power equipment, and tank service companies and industrial service providers that never quite know what the next tank cleaning job is going to involve.
