ABOUT THE Product
R404A Refrigerant OVERVIEW
R404a is an HFC mix refrigerant gas. It’s mixture consisting of R125 (44%), R143a (52%) and R134a (4%). R404A refrigerant is commonly used in low and medium temperature refrigeration applications. It has long replaced refrigerants R502 and R22, which are used in commercial refrigeration equipment.
APPLICATIONS
Low & medium temperature refrigeration:
- Commercial Refrigeration
- Industrial Refrigeration
- Transport Refrigeration
- Cold storage cells, ice and vending machines
LUBRICANTS
- Polylol Ester
REPLACEMENT
The replacement or alternative refrigerants for R404A include the following, for example:
- natural refrigerants, such as ammonia NH3 and carbon dioxide CO2, GWP = 0
- new replacement refrigerants, such as R1234yf and R1234ze, GWP < 10
- it will be replaced with refrigerants with a lower GWP, such as 448A, 449A and 455A, depending on the system and purpose of use.
