The 820-DS (Dual Stage) LPA® (Liquid Pressure Amplifier) is now available for high lift liquid line applications, superheat-suppression, compressor oil cooling, DX-Re circulation and the usual floating head pressure energy saving initiatives for refrigeration systems world-wide. The 820-DS has been designed to provide continuous operation up to the critical pressures of Co2 and has been developed with minimal power  and low net positive suction head conditions in mind, the 820-DS-075 exceeds that criteria.
