Yes. We will package the goods ready for transit and will inform you when the goods can be collected. This option is particularly useful if there is a container of goods going to a country by sea.

Yes. We have recently developed a dosing system which delivers Biocide at set intervals as a preventative measure for bacterial infections. Of course our fuel polishing units can also remove any bacteria down to 2 micron aswell.

Yes. We have a couple of tried and tested methods to avoid this happening including an automatic sensing and heater add-on. Please contact us for more information.

If you are new to fuel polishing, trying to decipher which system will best suit your requirements and budget can be quite daunting.

We firstly recommend you read our "Guide to Fuel Polishing"

• get an insight in to what fuel polishing is
• know about fuel contaminations and their effects
• see how our units work

To select which unit suits your requirements, we recommend using our new Product Selector Widget. Alternatively, you can contact us so our fuel cleaning experts can advise you.

The quickest and easiest way of finding out what is buy using our new Product Selector Widget.

The system you need will vary based on the following factors:

• Tank size and fuel amount
• the speed which it needs to be cleaned
• Power (12v, 24v, 220v)
• Type of generator (main generators, day generators and boats)
• Location of fuel tank ie internal or external
• Other important factors- portable unit, stair climbing unit,
• Additional items you may not have considered- drip tray, automatic change over, field bus communication, dosing control
• Specifications (field bus communication, etc)
• Budget

What makes WASP PFS Ltd unique is our skill and ability to design and build our own systems. This gives us the flexibility and expertise to design and manufacture products specific to your budget, requirements and specifications. View some examples of bespoke systems.

Our standard system begins at 8 lit/min 24v DC powered, and ranges up to 400 lit/min 220v 50hz 1ph AC powered. We custom build as well, with our largest unit currently being able to handle up to 1600 lit/min (that's nearly 100,000 litres per hour).

Systems typically have manual, automatic (programmable timer) and BMS (Building Management System) control as standard. They are self pumping and self monitoring fuel cleaning devices which are typically installed near to your fuel tanks. We also offer portable systems, units in IP rated enclosures, and frame mounted units and field bus communication options.

For more advice on selecting the unit to suit your requirements, please contact us.

We have customers all over the world, including Europe, Saudi Arabia and Iceland and likewise we have a large world-wide distributor network.

We have detailed instructions on the ideal positioning of the units to achieve optimum performance, here is some basic information on the W-PFS and WB Range installation.

W-PFS Range Units

• Ensure the system is securely fastened to a wall or other suitable solid structure.
• The unit should have unique pipe work from any existing fuel driven equipment. The input to the WASP system should feed from the bottom of the fuel tank (via a ball valve and a foot valve or non return valve)
• The system should pick-up fuel from the lowest point of the tank at one end, (below the level of the fuel feed to your engine) and ideally return it to the highest point at the opposite end.
• The output should return to the tank at the top, opposite end to the input ideally.
• The unit can be controlled via BMS (Building Management System), however it is capable of self operation and monitoring.
• System must be primed before use and operation. It must also be primed after servicing; although with the aforementioned foot or non return valve installed, priming should only need to be done once after installation.
• With power applied, please ensure the system’s time and date have been correctly set.
• We recommend an internal pipe diameter of 3/4” for the 010 model and 1” for the others; however larger diameters will assist the unit as this reduces the frictional losses. Small diameters, long pipe runs or many bends in the pipe work will cause high frictional losses and cause the system to run slower than its maximum speed, or in extreme cases cause it to stop. Likewise high fuel lifts or fuel heads will also cause the unit to run slower.
• In any typical fuel tank, the pipe feeding fuel to the engine is not at the bottom, however to successfully clean fuel, the pickup pipe going to the W-PFS unit should be right at the bottom of the tank, below the engine feed.

WB Range Units

The WB range of products is typically wall mountable and should be installed close to the fuel tank it is cleaning.

In any typical fuel tank, the pipe feeding fuel to the engine is not at the bottom, however to successfully clean fuel, the pickup pipe going to the WB unit should be right at the bottom of the tank, below the engine feed.

The return pipe from the WB unit should ideally be at the top of the tank at the opposite end to the pick up; if this is not possible the top of the tank at the same end is acceptable.

Apart from that, the list below highlights our recommendations.

• A fused spur is required to power the system (24v DC or 220v 50hz 1ph AC).
• Only two pipes are required (input/pickup and output/return)
• We recommend a non return valve on the input pipe
• Alternatively we recommend a foot valve at the tank end of the input pipe
• We recommend isolating ball valves before and after the system

We will work with you to customise the appropriate W-PFS unit to suit your specific requirements.

There is a range of Add-ons to our standard W-PFS range which include, heaters, fans, trolley fittings, stair climbing units, custom size units, dosing systems and many more.

To see examples of some recent custom made units, have a look at our Bespoke Systems page.

We recommend elements on systems are changed at least every 12 months (more often if there is a warning that the filter is full). Seals should be checked every six months and replaced at least every 36 months.

Instructions on changing elements and seals are in the original instruction manual you would have received with the unit. If you order Complete or Element service packs, you will receive a service instruction booklet with detailed instructions on changing spares and the service tasks. For more information on spares, see our dedicated page.

You are not alone. Time goes by and it is easy to lose track of how long ago the system was serviced.

We have recognised this issue and created a service sticker (like something your boiler service engineer would stick on the side of your boiler).

The stickers are included in the Complete and Element Service Packs. Simply complete the label with your details and the date and stick to your WASP PFS System. This acts as a reminder to service the WASP unit frequently to achieve the best results from your fuel cleaning system. For more information on spares, see our dedicated page.

You will find your the model and serial number of your WASP PFS Fuel Polishing System on a steel plaque on your unit. If you need any help identifying your unit, please contact us.
