Thermo King makes R452A refrigerant standard

Thermo King is making R452A refrigerant the standard option on single- and multi-temperature truck refrigeration units made in North America.

The refrigerant with a lower global warming potential (GWP) is available in T-Series self-powered truck refrigeration units for Classes 5-7 and the direct-drive V-Series truck refrigeration unit for Classes 1-4.

The same option was announced for Precedent trailer units in January 2022.

Standard V-Series truck units for fresh setpoints will continue to use the low-GWP R134a refrigerant.

Self-powered truck refrigeration units (typically for Classes 5-7) are included in the California Air Resources Board (CARB) 2023 requirement for all transport refrigeration units (TRUs) run in the state, requiring a GWP of 2,200 or less. Direct-drive truck refrigeration units typically found in Class 1-4 are not included.

Thermo King has been using R452A for its entire EMEA portfolio for several years and select products in North America and in Asia Pacific.
