Future-Proof CO2 Refrigeration Solutions

CO2 Refrigeration Takes Compliance Out of the Equation

CO2-based commercial refrigeration is emerging as a preferred global technology to transition away from HFC-based refrigerant use. But realizing its potential means solving the entire equation. With scroll and semi-hermetic CO2 technology, onboard diagnostics and complete CO2 system communications— all from Emerson—the full promise of CO2-based refrigeration is achievable. We’ll help you exceed your energy and environmental targets, achieve regulatory compliance and gain lasting peace of mind about your refrigeration strategy.

Supermarkets, in particular, have led the way through the wider adoption of carbon dioxide-based (CO2) refrigeration systems. As a natural re​frigerant, CO2 (or R744) has many advantageous properties, including: nonflammable, low toxicity, neutral ozone layer depletion and negligible global warming potential. Its excellent thermal properties make it an especially viable option to reduce HFC usage. However, CO2 is not without its challenges. It can operate at very high pressures (above 1,500 psig), and is susceptible to decreasing efficiency in high ambient temperatures.

At Emerson Climate Technologies, we offer a full suite of refrigeration system components necessary for the successful implementation of R744, including: system controls, compressors, flow components and system protectors. And, we’re pioneering ways to adapt CO2 refrigeration systems to high ambient environments. Click the images below to see how our products are applied in various CO2 systems.

The commercial refrigeration industry is in the midst of transitioning from HFC-based refrigerants to natural alternatives. The reasons are three-fold: 1) to eliminate the negative environmental impacts from potential direct HFC emissions; 2) to comply with ever tightening environmental regulations; and 3) to implement future-proof refrigeration systems that exceed regulatory, efficiency and environmental objectives.
