The Thermodynamic Principles of LPA

Most current refrigeration and air conditioning systems waste 20% to 40% of

Co2 Liquid Refrigerant Pump & LPA Economizer

The LPA® pump is an open-drive sealed unit with important design features:

DXFC™ Wall Mounted Split AC unit with Outdoor Condenser

[Public Disclosure-23rd October 2016] DXFC, DX free cooling the alternative to running



809-SS-050-STD-B     Flow rate 0.5 to 4.5 GPM  |  1.2 to 17 Litres/min

The 809-SS-050-VSD-B is supplied with either Copper or K65 connections rated at at 50 or 80 bar PS. Stainless steel connections are available.

The 809-SS series LPA® (Liquid Pressure Amplifier) is used in a variety of refrigeration and air conditioning applications . Other applications include, superheat-suppression, compressor oil cooling, DX-Free Cooling and DX Re Circulation and energy saving initiatives for refrigeration and air conditioning systems. The 809 is developed to provide continuous operation and minimal power consumption.

    Could you please provide examples , where a 120bar CO2 pump cpould be used in a refrigeration system ?
    I see you are expert in high pressure pumps. Do you produce also expander units for CO2 applications ?

  2. Engineering says:

    Gaal thanks for your post. We have developed LPA pumps to meet with these higher pressures as a safety factor for when equipment fails in hotter environments. Other applications include pumping liquid that has been previously cooled and condensed.
    Have a good day.
