Solstice® L40X (R-455A) is an excellent refrigerant option for commercial refrigeration low-temperature applications such as plug-ins, condensing units, food service, water-loop systems and similar. Its low GWP, extended operating envelope, high efficiency, high critical temperature and low critical pressure makes it a potential match for other applications such as supermarkets, chillers, heat pumps, transport refrigeration, and others.
Solstice® L40X (R-455A) vs CO2
- Solstice® L40X (R-455A) provides energy efficiency improvement over CO2 and reduce overall CO2 footprint (Scope 1 and Scope 2 emissions).
- In contrast to CO2 based systems, which demand specialized skills and capabilities, Solstice® L40X (R-455A) systems follow standard installation and maintenance practices, requiring no elite skillset and experience.
- Unlike CO2 refrigeration systems, Solstice® L40X (R-455A) has a lower CAPEX requirement. CO2 being a high-pressure refrigerant, its systems need entirely new equipment and costly components to withstand high pressure conditions.
