In the summer of 2024, Energy Recovery conducted a rigorous measurement and validation (M&V) program to assess the performance gains achieved by incorporating the PX G1300 into diverse CO2 refrigeration system designs and load sizes.
The PX G1300 pressure exchanger is a versatile solution to simplify energy efficiency for CO2 refrigeration. It can be seamlessly incorporated into new systems or retrofitted onto existing racks with the compact, predesigned PX Energy Optimizer module. The PX G1300 can deliver as much as 30% peak COP lift with projected annual energy savings of up to 15% or more.*

The PX G1300 reduces flash gas in CO2 systems, improving energy efficiency and increasing system capacity. In normal system conditions, it saves energy, decreases dependence on water spray systems, and provides operational flexibility. Under high temperature stress, the PX G1300’s reduction in flash gas offers extra capacity and high temperature rack stability to protect against high-pressure discharge failure and associated downtime.
In a 150 kW system, incorporating the PX G1300 can increase system capacity by up to 15% at 35°C/95°F*, as measured by a reduction in flash gas through the MT Compressor, or result in a 6°C/11°F rise in design temperature to safeguard against heat waves.
