Fuel polishing systems are vital for diesel-powered emergency systems. They remove a critical point of failure: fuel contamination. Modern engines and fuel systems need clean fuel to run reliably.

If left untreated diesel is under constant attack from water, microbial growth and solid particulates, even after cleaning. There is a solution. Diesel Defense units preserve your stored fuel to EN590 standards, greatly improving the reliability and dependability of your critical systems such as standby generators and fire pumps.
