The Reverso Pumps DFS Cart Difference

The Diesel Fuel Service Cart (DFS Cart) from Reverso Pumps, Inc. is the first portable 3-in-1 fuel polishing system on the market that is lightweight, streamlined and designed to meet exacting industry standards for safety and efficiency. The compact DFS Cart can be maneuvered and operated by one person and wheels easily up to a vessel, tank or equipment. It also can easily go up-and-down stairs due to the built-in skids.

The DFS Cart utilizes the world-class 5-stage Separ Filter fuel/water filtration system that removes water and 99.9% of particulate from diesel fuel. Unlike competitor carts, the Reverso Pumps DFS Cart has numerous safety and environmental features including maintenance alarms, clogged filter alarms, a drip pan for spillage, shut-off valves and water level shutdown features.

The DFS Cart not only polishes stored fuel in underground and above-ground storage tanks, but also cleans the fuel when dispensing into equipment or polishes the fuel already in tanks.

WHAT IS FUEL POLISHING?

Fuel polishing is the process whereby diesel fuel is moved through filter media using a pump which operates independently of any other pumps on board a vessel. Fuel polishing is most commonly found in the marine industry, in particular yachting where vessels remain idle for extended periods of time.

The typical fuel polishing system consists of a pump/motor which is electrically powered, 12VDC, 24VDC, 110VAC or 240VAC. Again, these are the most typical. Also, the fuel polishing system consists of a fuel filter/water separator. One essential of a fuel polishing system is a vacuum gauge which will indicate the cleanliness status of the filter element found in the filter housing.

Fuel polishing systems must be capable of removing water, very fine particles (1-5 microns in size) and most importantly, moisture. There are numerous fuel filters which do an adequate job of removing water and particulates, however, unless they remove moisture, the microbes will continue to grow in the fuel tanks.

To be effective, fuel must be polished regularly. The entire volume of the fuel tanks must be circulated through the described filters four or five times a month. (MORE IS BETTER) Polishing fuel can be likened to polishing silverware, it takes many "passes" and it takes "frequent" passes in order to maintain the fuel (silverware) in tip top condition.

Once a year polishing is a thing of the past. With the newer diesel engines, there is a cleanliness standard which is far more stringent than that of days gone by. If you, the typical yachter, pleasure boater have experienced clogged filters, you know how aggravating that can be not to mention the danger of engines shut down in rough seas or critical situations.

Other fuel polishing scenarios include stationary generators, remotely located seasonally operated equipment such as agricultural pumps, oil field pumps etc. There are no doubt numerous applications, all of which share the same common denominator, idle fuel.

Google fuel polishing and you are sure to find several companies competing for their share of the market. A word of caution, be sure to address the MOISTURE question with whomever you contact. Also compare water removal capacities and size of particles removed. DON'T buy the cheapest, BUY THE BEST.

Typically smaller systems are cheaper and inadequate. Many systems offer the same inadequate filters that you may already have. More of the same is not the answer. Look at the customers' comments if they are available. Your peers are a good reference. Look at the company you are considering dealing with. Who are they doing business with.

Finally, fuel polishing is a long term investment. If you are a "long term" owner, then fuel polishing is for you. Simply stated, if you want your equipment to operate effectively for the long haul, invest in the "stuff" that will keep it in operating condition continuously.

A common question we receive:
…“One of the worst problems we face with the reliability of our engines is the effect of bad fuel on the fuel injection system. This is true for most diesel engine manufacturers that make use of the latest technology in their electronically controlled engines. Although the manufacturer specifies water separators as primary fuel filtration (10 microns) and a 2 micron high efficiency secondary fuel filter system, we still have issues (even using the fuel they recommend) due to the quality of the fuel that is standard in our environment… We find that even with the best precaution methods, injectors have premature failures due to free water that bypasses all the systems in place. What else can we do to reduce system failures due to fuel?”

Answer:
We understand your problem and agree that today’s high-tech engine fuel systems have an Achilles Heel - Water.

Our fuel polishing systems, utilizing Separ Filters, remove up to 99.9% of all water and particulate. The best way to illustrate the need for and success of these systems is to showcase the following case. This photo below is from the U.S. Embassy in the UAE taken by Embassy staff.

Their problem was similar to yours in that they had fuel deliveries that were badly contaminated with water. This water destroyed several Cummins injection pumps and countless injectors. The picture (below) is the before and after just one (1) pass through our fuel polishing system. Since they started using the Portable Cart system, they have not had a single fuel-system related failure.

Storage of diesel is often an overlooked area – a popular misconception is that diesel fuel is “good for life”.
The reality is very different.

To fully understand the issues at play, it is worth taking into account several areas:
• The Diesel fuel quality standard
• The specification of supplied diesel
• Known issues
• Recommendations from the fuel supplier
• Discovering issues before they become problems
• Short and long term solutions

To look at these issues, we have been in conversation with BP and have utilised their available library of fuel data.

Fuel Polishing for the TRINIDAD AND TOBAGO COAST GUARD 

This is an extreme case as the fuel sat unused in contaminated tanks for nearly two years. A Reverso 600 GPH was used to complete the polishing. The FPS 210 can perform equally well and the FPS 150 is good for smaller tanks and the FPS 80 for very small tanks.

Q: Which element should I use for relatively clean (maintained) fuel. The stainless steel filter units last a long time, therefore, wouldn't it be practical to use this rather than keeping a stock of paper filters?

A: The Stainless Steel element is rated at 30 or 60 Micron and is designed for removal of large particulate in a very dirty tank to avoid wasting a large number of elements. Since your fuel is maintained (or of relatively clean quality), we recommend the paper elements.

If your tank was/is clean to begin with, and you are just removing the particulate, you would typically only use 2-3 elements per year. This option will extend the life of your fuel by at least 1-2 years and is much cheaper than replacing the fuel on an annual basis.

Q: How often would you recommend that we polish our diesel fuel?

A: Fuel polishing, in our opinion, should be a semi-continuous process. As the tanks heat up and expand during the day and contract at night drawing in the moist night air, water vapor condenses and drops to the bottom of the tank.

If the system were to run once per week long enough to filter 25% of the tank, you would not have any problems with your fuel. This will extend the life of your fuel from one year to two or three years. You would not have to replace the fuel on an annual basis - just the filter elements.

Q: Our largest tank is 9000 liters.  This means that the FPS-210 would need to run for over 11 hours to treat the entire contents, while the FPS-600 would take 4 hours.  Our other tanks are much smaller, however, and it would be practical to have the lighter-weight FPS-210 unit for moving around our site.  What's you suggestion?

A: If you were to permanently install an FPS210 on the 9,000 ltr tank and allow the polishing to run three (3) hours once a week - you would filter the entire tank. This equates to 12 cycles per month. The cost of replacing 9,000 liters of fuel each year is much higher than the retail cost of a FPS210 Enclosure unit. The unit would pay for itself the first year. The only maintenance cost would be the replacement element once per year (or as needed) for under $50.00 US.           

For all of your smaller tanks, provided you have the manpower to filter all of the tanks every six (6) months, a 210 or 600 gph portable unit would be satisfactory. This will allow you to stop throwing expensive fuel away. Again, the ROI is one (1) year or less.
