R452A refrigerant is a HFO refrigerant with zero ozone depletion potential and low global warming potential. R452A refrigerant is mainly used to replace R404a and R507a refrigerants in volumetric, direct expansion, medium and low temperature commercial, industrial and transportation refrigeration systems. The R452A is suitable for new equipment installations and retrofits of existing equipment, providing similar energy efficiency and improved environmental characteristics without increasing the compressor’s exhaust temperature.

R452A refrigerant composition:

Molar percentage: R32 accounts for 21.8864%, R125 accounts for 50.8838%, and R1234yf accounts for 27.2298%.

Percentage of mass: R32 accounts for 11%, R125 accounts for 59%, and R1234yf accounts for 30%.

R452A application range:

Medium and low temperature direct expansion transport refrigeration system

Large refrigerated truck

2. Light refrigerated truck

3. Refrigerated container

Medium and low temperature direct expansion industrial refrigeration system

New equipment installation, existing equipment renovation

R452A advantages:

Low global warming value (GWP): GWP is 45% lower than R404a and R507

Similar to the exhaust temperatures of R404a and R507

Same mass flow rate as R404a and R507, no need to adjust thermal expansion valve

Nonflammable

Compatible with existing equipment and lubricants

Can be raised directly after the leak
