DDF1 Fuel System

IPU Diesel Defence DDF1 on-tank fuel polisher

IPU Diesel Defence DDF1 on-tank fuel polisher

Stored fuel in the tank will deteriorate over time due to oxidisation and microbial activity, and tank storage is more susceptible to microbial activity as sludge is often found at the bottom of these tanks, but our DDF1 Fuel Polishing System could answer this problem.

With this in mind IPU have developed a new range of fuel polishing units specifically for tank polishing: on tank units.

The DDF1 Fuel Polishing System is a compact wall-mounted fuel polishing cabinet designed specifically for the removal of particulate and water moisture contamination that can accumulate in stored fuel over time. With dual particulate and water removal and flow rates of up to 50 l/min the DDF1 Fuel Polishing System will leave your fuel ready for use anytime.
