Purge / Fill Systems

Pacific Design Technologies (PDT) engineers, designs, and manufactures Purge/Fill Systems for the space, aerospace, and defense industries. These systems use specialized fluids such as:
  • PAO (Polyalphaolefin)
  • EGW (Ethylene Glycol and Water)
  • PGW (Propylene Glycol and Water)
  • Jet Fuels
  • Hydraulic Oils
  • Liquid CO2
  • Ammonia
  • Refrigerants
  • Deionized Water
  • Coolanol 25R

PDT designs purge/fill systems for use in fluid circulation in liquid cooling system and lubrication systems. These purge/fill systems can be used in ground vehicle and military aircraft applications. PDT offers non-powered and powered systems depending on the application. The powered systems can be designed to operate on various power supplies.

Non-powered systems are designed to use the on-vehicle pump to circulate the working fluid, perfect for remote servicing. The powered systems incorporate their own pumps for fluid circulation.

PDT Purge/Fill Systems allow for the following modes to be accomplished, depending on the application:
  • Filling
  • De-aeration (purging of entrained air)
  • Accumulator Charging
  • Draining
