Carrier Transicold will begin offering the new-generation refrigerant R-452A as an alternative for use in its truck and trailer refrigeration systems, following the July 21 announcement that the Environmental Protection Agency has approved the refrigerant for transport refrigeration applications.

Developed by the refrigerant manufacturing industry to reduce environmental impact, R-452A has a global warming potential (GWP) that is almost half that of R 404A, the hydrofluorocarbon (HFC) refrigerant used in most land-based transport refrigeration applications. Carrier Transicold will offer the new refrigerant as an option to R-404A later this year.

R-452A is a refrigerant blend with a low-GWP hydrofluoroolefin (HFO) as one of its key components.

Carrier notes that the EPA has not banned R-404A for transport refrigeration applications, enabling refrigerated haulers to choose the option best suited for their operations. This allows for considerations of price and availability, fleet size and maintenance budgets.

While Carrier Transicold will continue to offer R-404A, it will also provide R-452A as an option for new model Vector and X4 Series trailer refrigeration units, Supra truck units and direct-drive truck units that currently use R 404A. The new refrigerant can also be used as a drop-in replacement for Carrier Transicold units already in service, although certain older models may require component retrofits or software updates, which can be accommodated through Carrier Transicold’s network of authorized dealers.

CO2 refrigerant has a GWP of only 1, roughly 2,000 times better than R 452A and 4,000 times better than R-404A. It is also non-flammable, non-ozone-depleting, globally available and cost effective. Carrier has successfully applied CO2 refrigerant in CO2OLtec stationary commercial refrigeration systems widely used throughout Europe, in NaturaLINE container refrigeration systems used by major container shipping lines in support of global commerce, and prototype trailer refrigeration trials with two major European supermarket chains.
