Phosphate Ester Fluid Solutions

Phosphate ester (PE) based hydraulic & lubricating fluids (i.e. Fyrquel EHC or 220, Pyroguard) are used extensively in critical systems where fire-resistance is a requirement.  Millions of dollars and thousands of downtime hours are wasted each year by power plants, military and industrial users who need solutions to properly maintain PE fluids.  Many of these users have accepted the consequences that come with unmanaged phosphate ester such as:

  • Premature fluid replacement or bleed and feed
  • Contamination related servo valve failures (turbine trip)
  • Gelling & deposit formation (dissolved metal catalyst)
  • Expensive system flushing
  • High acid number
  • High moisture content
  • Dark fluid, foul odor (thermal degradation)

We believe it is time to rethink phosphate ester fluid maintenance and demonstrate that PE fluids are not a consumable fluid to be periodically replaced. We also hold  that Phosphate ester (PE) can be very reliable and provide years of trouble-free operation if properly maintained.  We offer technologies that remove 100% of the contaminants that plague PE and restore fluid systems to peak performance.
