What is a Pressure Exchanger and How Does it Work?

Pressure exchangers recycle pressure energy from high-pressure CO2 to low-pressure CO2. Similar to a heat exchanger, which exchanges heat between two fluid streams, the pressure exchanger transfers pressure energy. Pressure exchangers can function as a compressor and high-pressure valve within a CO2 system and use almost no electricity compared to the system.

When integrated into new or existing systems, the PX G1300 pressure exchanger can reduce compressor workload to increase cooling capacity, system stability, and energy efficiency.
