Carrier Transicold makes R-452A standard this year
Carrier Transicold will adopt R-452A refrigerant as the standard for all its transport refrigeration units in North America later this year, embracing the lower global warming potential (GWP) that comes with it.
The company’s refrigeration units have been able to use R-452A since 2017, and it’s been a customer-specified option for several years. The refrigerant is already standard with some newer products.
The R-452A will in October become the standard in models that currently use R-404A.
Canada will require refrigerants with a GWP of less than 2,200 in new transport refrigeration units in 2025. R-452A has a GWP of 2,140, while the R-404A has a GWP of 3,922.
California will have the limits in place in 2023.
Late-model Carrier Transicold systems with an electronic expansion valve can also be upgraded to R-452A with a software upgrade and purging of R-404A.
