AXI (formerly ALGAE-X®) SMART Fuel Polishing Systems (FPS) are programmable, fully automated Fuel Maintenance Systems that remove water, sludge and contaminants wherever fuel is stored or used. Adding a SMART FPS SX System that meets your requirement and needs will remove particulate, separate water, and condition fuel. This fuel polishing process conditions and stabilizes diesel and bio-fuels, eliminates microbial contamination, and ensures fuel remains clean and dry. These compact fuel maintenance systems are specifically designed for permanent installations indoors, as well as confined spaces, such as inside gem-set enclosures or engine rooms. SMART FPS Systems keep your tanks clean and your fuel in "Clear & Bright" pristine condition at all times. AXI’s LG-X Fuel Conditioner, included on every FPS System, reverses fuel deterioration and removes sedimentation to sub micron levels, preventing clogged filters, extending injection system service life, and reducing smoke, emissions and downtime.

Fuel has a limited shelf-life and even "fresh fuel" could contain water, sediment and microbes upon delivery. Fuel filters should last thousands of hours. However, frequent filter changes, tank cleaning and replacing fuel have become common maintenance practices that address the symptoms of poor fuel quality, not the problem itself.
SMART FPS Systems reverse fuel deterioration while decontaminating, cleaning and optimizing the fuel for reliable, continuous, uninterrupted service.
For safe operation, the SMART FPS SX, SX-F and SX-R are all equipped with an automatic pump shut-down and indicators when filter elements require service. Also included are indicators for high pump vacuum, pressure exits and leaks.
Generators and pumps operating in remote locations are ideal applications for SMART FPS Systems. Fuel has a limited shelf-life and even "fresh fuel" could contain water, sediment and microbes upon delivery. Fuel filters should last thousands of hours. However, frequent filter changes, tank cleaning and replacing fuel have become common maintenance practices instead of serious warning signs of fuel problems.
Choosing the Right System
SMART FPS Systems reverse fuel deterioration while decontaminating, cleaning and optimizing the fuel for guaranteed continuous, uninterrupted service.
The FPS SX and SX-R System are similarly configured in all respects with the exception of the primary Filter.
The FPS-SX utilizes a Separ SWK 2000/10 Fuel Filter / Water Separator that incorporates an effective five stage system for the separation of water and particulate from fuel. Both water and particulate matter can result in high wear and tear for fuel pumps and injectors, resulting in reduced reliability and expensive engine repairs:
Stage 1: From the inlet port, fuel flows through the interior vane system which imparts a circular motion to the fuel.
Stage 2: Still in circular motion fuel reaches the bowl section where, due to this centrifugal motion water droplets and heavier particles are forced to the wall of the bowl eventually settling in the bottom of the bowl.
Stage 3: In this stage the fuel has to pass the vane system positioned on the "outside" of the central housing. Due to differing length of the vanes and the twofold rapid change of fuel flow direction, smaller water droplets and finer particles will settle on the vanes. These settlements will agglomerate and when heavy enough fall to the bottom of the bowl. Already at this point the major portion of any contaminates in the fuel have been separated.
Stage 4: Just below the filter element the flow area of the filter is increased significantly thus reducing the fuel flow rate. This calming effect allows even smaller water droplets and particulate to fall out settling on the inner surfaces of the housing forming larger droplets which eventually fall into the bottom of the bowl by gravity. Due to the before described pre-separation process the major portion of water and particulate present in the fuel will be in the bowl or on the inner surfaces of the filter thus greatly extending the filter element life.
Stage5: The final filtration of the remaining water and particulates still contained in the fuel will be effected by a replaceable filter element. These filter elements are produced from a special filter media and are available in different pore sizes. The clean fuel leaves the filter via one of the two outlet ports.
Stage 1: Separation - As fuel enters the assembly, it moves through the centrifuge and spins off large solids and water droplets which are heavier than fuel and fall to the bottom of the collector bowl.
Stage 2: Coalescing - Small water droplets bead-up on the surface of the conical baffle and cartridge element. When heavy enough they too fall to the bottom of the collector bowl.
Stage 3: Filtration - Proprietary Aquabloc II cartridge elements repeal water and remove contaminants from fuel down to 2 micron. Aqua bloc II cartridge elements are waterproof and effective longer than water absorbing elements.
The FPS SX-F System utilizes the same Separ SWK 2000/10 Fuel Filter / Water Separator described above, and also uses as secondary filtration spin-on filter. For most applications where fuel is stored for for future use, a circulation system that consistently maintains water-free fuel storage and fuel filtered to a particulate level of 10 microns is acceptable. Engine manufacturers generally want their engine fuel systems to be fed fuel that has been filtered to 4 microns or finer. The engine filter, through which the stored fuel will pass, will typically be capable of filtering fuel to the level required by the manufacturer of the engine. But having a secondary filter that has the capability of filtering to a finer particle level of one micron presents a degree of assurance that many maintenance professionals feel is worth the extra effort. In addition, having the secondary filter having the capabilities of having a water block filter element, an element capable of removing emulsified water from the fuel, also presents the opportunity to have confidence that the fuel is as clean and pure as is capable to assure that when the lights to out your fuel will be there to power your backup generator.
The System Controller
The FPS SX and SX-R Systems utilize the SFC-50 controller. This controller system monitors the performance of all components in the FPS system and automate the fuel maintenance cycles. The system is automatically operated by the programmable UL508A SMART Filtration Controller with text readout. The controller is full programmable, fully automated, has digital text readout, and has a Building Maintenance System/Building Automation System (BMS/BAS) interface. The system gives the operator an instant visual status report of system power, pump operations, and alarms for high vacuum and high water levels. A selector switch allows the option of manual operation or running the fully automated program.
The controller’s alarm functions and pump shut-down are triggered if filter elements require service, if high pump vacuum or pressure occurs, if system ﬂow rate varies or if there is water in the separator. The wiring harness with plugs easily connects the SMART Filtration Controller with the FPS allowing for greater flexibility in installation and access where it’s most convenient. The controller can also be used with an optional remote pendant power control switch and an alarm strobe light for high visibility.
The FPS SX-F utilizes the SFC-55 controller. This controller includes all the capabilities of the SFC-50 Controller with additional functionality required for the additional components incorporated into the FPS SX-F System.
The principal components are a continuous-duty pump with primary filter/water separator with vacuum sensor and gauge, an AXI Fuel Conditioner and a SMART Filtration Controller. The primary filter protects the pump, coalesces and removes water and particulate. The patented AXI Fuel Conditioner prevents and reverses fuel degradation, agglomeration and microbial contamination.
Implementing SMART FPS Fuel Polishing and Transfer Systems will guarantee Optimal Fuel Quality for Reliable Power At All Times. SMART FPS Systems prevent downtime, periodic tank cleaning, replacing out-of-spec fuel and fuel-quality related injection system repairs.
