PX G1300

PX G1300™ Pressure Exchanger
for CO2 Refrigeration and Other CO2 Systems

Lower operating costs and energy consumption, increase efficiency, and meet your sustainability goals

PX G1300 pressure exchanger for CO2 refrigeration systems

The PX G1300TM utilizes proven technology to improve the energy efficiency of CO2 systems, reducing energy costs, lowering capital costs of the system1, and reducing CO2 emissions.

Its simple design and precision manufacturing ensure that the PX G1300 is highly reliable and durable, with little to no scheduled maintenance, and can be integrated into existing and new high-pressure CO2 systems. It also can safeguard CO2 systems as global temperatures continue to rise, as it performs even more efficiently at higher temperatures.2

Industry Recognition

How It Works

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

Based on laboratory and real-life results, the PX G1300 device can increase the energy efficiency of CO2-based commercial refrigeration systems by more than 25% at 35-40°C (95-104°F) and more than 30% above 40°C (104°F), compared to a standard CO2 system with no energy recovery devices or systems.

Solutions for a Wide Range of Temperatures

Whether it’s heat waves or cold snaps, refrigeration systems need to perform. The PX G1300 offers high temperature rack stability, but also performs even more efficiently at higher temperatures. At an installation in Northern Italy, it improved efficiency by more than 30% at temperatures above 40°C (104°F).
