Provan Fuel Management (PFM)
How PFM Units Work
The PFM unit is basically a metal box with a through hole, which diesel fuel flows through the unit without mechanical filtration. The fuel is treated with magnetism and ultraviolet light to kill the diesel bug and remove the water. The combination of these features is how PFM units create super clean diesel fuel, known as fuel polishing. If there is a power failure to the unit, then the fuel flows through uninterrupted. The blue LED lights on the unit indicate there is power to the unit and it is working, powered via the accessories circuit on vehicles. AC powered on Recirculating units.
What Are The Benefits of PFM Units
By killing diesel bug and removal of water from diesel fuel creates super clean fuel. This super clean diesel fuel in turn provides better combustion, provides fuel savings between 10% to 30%, eliminates diesel black smoke under load (unburnt diesel) which all diesels are known for, provides more (or restores) engine power, reduces harmful environmental emissions including NOx and SOx, and reduces engine maintenance costs.
How Do I Get Water in My Diesel Fuel
Diesel fuel is hygroscopic, meaning it absorbs water vapour from the atmosphere. Furthermore, during cool nights (requires only a 5 degree Celsius temperature drop) water condensate forms on the fuel tank walls and drips down into the diesel fuel. While the diesel fuel at a fuel refinery is to a high quality, once the diesel fuel is transported, the water absorption and accumulation starts from then on.
How Do I Get Diesel Bug in My Fuel
The presence of water, through the continual absorption of water into the diesel tank explained above, allows diesel bugs to grow and thrive. Diesel bugs comprise of bacteria, algae and fungus, which require oxygen (from water) to grow, breed and thrive, compromising the fuel quality in every diesel fuel tank and the performance of diesel engines.
Where Have PFM Units Been Used
PFM Units have been in use since 2009. Today, PFM units are in use in many countries and used in all manner of diesel engine applications such as 4WD's, trucks, ferries, boats, ships, marine pilot boats, diesel fuel power stations, hospital back up generators (UPS), data centres (UPS), mining vehicles, and many other applications.
PFM Inline units come in different sizes for different diesel engine sizes. The standard inline units range from 50 hp to 10,000 hp engines. For larger horse power engines, multiple standard units are used, or custom made larger units are made to cater for larger diesel engines. The standard units are readily available, while custom made units are made to order.
Recirculating units are used for fuel polishing large operational tanks, stagnant fuel tanks or storage fuel tanks such as back up generators for uninterruptible power supply sites like data centres, hospitals, diesel peaking power plants, remote diesel tank sites and many more. Each Recirculating unit is custom made depending on the size of the fuel tank and the control features required by the customer.
Types of Fuel PFM Is Used For
PFM units are used to super clean, or fuel polish, diesel fuel, biodiesel fuel and heavy fuel oil (such as 180 CST low sulfur marine fuel oil), usually used for large cargo ships. PFM units clean contaminated diesel fuel and are able to maintain diesel fuel to achieve 18/16/13 particulate, Grade A Diesel, to ISO 4406 standard.
The PFM unit for heavy fuel marine oil looks a bit different but functions under the same principals.
Listen to the multiple benefits that Phil Allen experienced when he installed and used the PFM unit on his Toyota Landcruiser 4WD 4.5L V8 turbo diesel.
The benefits that Phil experienced included significant fuel savings, no more black soot exhaust when under load, quieter engine and less cabin noise. The most surprising benefit was the condition of the oil for his next engine service, the oil looked as new as reported by his mechanic. Such reported benefits are common and consistent amongst PFM users, noting that PFM units provide super clean diesel fuel to the engine, which achieve the results above.
