PX G1300™

Energy Recovery’s PX G1300 harvests the high-pressure energy of CO2 systems to reduce electricity consumption, thereby reducing operating costs and emissions. Similar to a heat exchanger which exchanges heat between two fluid streams, the pressure exchanger works by transferring energy from high-pressure to low-pressure CO2. The PX G1300 provides both expansion and compression to:

  • Increase cooling capacity
  • Increase system stability
  • Reduce energy usage

Energy Recovery’s PX G1300 works to maximize energy efficiency in a high-pressure CO2 system, transferring energy from high-pressure to low-pressure CO2. This efficient transfer of energy significantly reduces the system’s electricity consumption, lowering operating costs and emissions. Because it is able to provide both expansion and compression, it can also replace or reduce the size of existing system components, potentially lowering capital costs. Its simple and modular design means the PX G1300 can integrate easily into a range of systems and operating conditions.

While natural refrigerants offer a climate-friendly solution to many industries such as refrigeration, cold storage, and heating, the accompanying electricity costs can make high-pressure CO2 systems cost-prohibitive. By reducing these costs, Energy Recovery’s PX G1300 makes it easy to meet stringent emissions regulations and make a sustainable choice.
