Join our presentation, "Retrofitting CO2 Systems for Heatwave Resilience with the PX G1300 Pressure Exchanger", in the Refrigeration Forum on October 9 from 12:20 – 12:40 at Hall 7A, Booth 7A-638. The presentation will showcase how the PX G1300 can help supermarkets and other applications that are grappling with rising temperatures, high energy expenses, and excessive water usage.
What is the PX G1300?
The PX G1300 is a revolutionary application of pressure exchanger technology that provides energy-saving benefits to high-pressure CO2 systems. Energy Recovery’s PX® Pressure Exchanger® first entered the market over 30 years ago as an energy-saving solution for the seawater reverse osmosis (SWRO) desalination industry. Since then, pressure exchangers have made the SWRO treatment process commercially viable by reducing the energy consumption of a SWRO desalination system by as much as 60%.
How the PX G1300 Works
When integrated into a CO2 system, the PX G1300 reduces flash gas by delivering more liquid and less vapor to the flash tank. The PX G1300 pressure exchanger is a positive displacement compressor. It acts as a fluid piston, efficiently transferring energy between high-pressure and low-pressure liquid and gas through continuously rotating ducts. In other words, it captures energy in the system that would otherwise be lost and reintroduces it to the system.
A pressure exchanger has two fluid flow paths through a highly engineered ceramic rotor. The first is the motive fluid flow path, and the second is the driven fluid path. The motive fluid comes in at the highest pressure inside the PX G1300, while the driven fluid enters from the other side at a lower pressure. The motive fluid enters the system, pressurizes the driven fluid to high pressure, and then leaves the rotor as a low-pressure fluid. The driven fluid is then compressed or pumped to a higher pressure due to energy exchange with the motive fluid.
