Cost Savings Are Real

Custom built applications offer a real solution to fuel related problems and save you on the cost of filters, maintenance, downtime, and fuel loss by designing and integrating an efficient system that meets your needs.

More Than Filtration

Although classical filtration can remove contaminants, it only addresses part of the problem. Conditioning your fuel restores fuel to it’s original optimal state, or better.

Algae Does Not Live In Fuel

What many call “algae” is actually microbial growth from contamination. Fuel forms clusters and aggregations over time that will clog filters and form tank sludge. These formations don’t completely burn within your engine, causing less power, inefficiencies, and black smoke.

This automated AXI Fuel Oil Conditioning System treats all fuel going from the storage tanks to the GE turbine in a power plant in Qatar. It continuously provides optimal quality fuel with less than 2.6 ppm of contaminant at less than 5 micron in size and less than 200 ppm of water.

The skid is equipped with two filter/water separator vessels with coalescing and filtration elements. The water separated from the supplied fuel oil is collected and automatically drained. Its control panel, with all the safety and alarm functions, is directly wired into the plant’s business management center to be monitored and managed from the plant’s control room.

The system’s capacity is 30,000 liters/hour and operates at a continuous duty cycle flow rate of 325 liters per minute (86 Gallons per minute).
