Fuel Polishing question - Which element should I use?

- Monday, May 02, 2011
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.

Fuel Polishing question - How Often Should I Polish?

- Friday, April 29, 2011
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.

Clean Fuel Means Reliable Backup Power for Emergency Power Generators

The need for reliable backup electric power in data centers, healthcare facilities, telecom sites and other critical facilities is too important to leave to chance. In emergency power generation applications, a gen-set must be ready to run during very critical times – to do this you need to send clean fuel to the engines. Emergency power generators that rely on diesel fuel are at constant risk of unexpected failure due to clogged fuel filters. 
Because the engines used in these emergency power generators often sit without operation until they are needed to perform, poor fuel quality becomes a very common problem. If you have stored fuel, attention should be given to the condition of this fuel. Water build up in fuel is natural, as tanks collect condensation and water can leak in during fills and through vents. Also, changes in temperature can create an environment for bacterial growth in fuel, while natural oxidation and unavoidable fuel deterioration will lead to the formation of sludge, acids and tank corrosion. This sludge accumulates at the tank bottom over time, it is acidic and eats at tank walls and it clogs filters.
Several studies suggest that the overwhelming cause of most diesel fueled emergency generator engine failures is now fuel related, especially with today’s electronic injection systems.

You may already have a periodic preventive maintenance program in place for your emergency generator, but implementing a regularly scheduled fuel testing, cleaning and polishing program in order to proactively detect problems and correct them before they impact you critical system is a good idea.

The results from adding emergency generator fuel tank cleaning and polishing to your regular maintenance schedule:

More reliable power for improved safety
Improved engine performance
Clean internal engine components
Fewer injector failures
Reduction of maintenance, downtime and operating costs
