R-452A
Technical overview
R452A refrigerant for compatible transport refrigeration
R452A is a zeotropic HFC/HFO blend associated with low- and medium-temperature transport refrigeration. It is used in approved equipment and selected conversion applications where the system manufacturer supports it. Match the refrigerant to the transport unit specification; this is not a general-purpose substitute for passenger-vehicle air conditioning refrigerants.

Service considerations
A qualified technician should review compressor compatibility, controls and service requirements. A1 classification does not eliminate pressure or exposure hazards, and the blend still requires appropriate handling and recovery equipment.
Compatibility & handlingR452A is not a drop-in replacement for R134a or R1234yf vehicle A/C. Similar application labels do not make different refrigerants interchangeable.
