Characteristics:

R452A is a non-ozone depleting, non-flammable refrigerant blend designed as a lower GWP alternative to R404A and R507 in low and medium temperature applications. In
transport, R452A has been found to have the same cooling capacity, fuel efficiency, reliability and refrigerant charge as R404A, according to end users. Similar performance R448A. Kirby recommends alternative refrigerants with
substantially lower GWP.

Physical Attributes:

• ODP: 0
• GWP: 2140
• Class/ Type: Zeotropic blend (A1)
• Refrigerant Kind: HFC/HFO
• Oil Type: Polyolester Oil (POE)
• Glide: ~ 3K

Performance:

• R452A can be retrofitted to direct expansion systems using R404A or R507 without change of components
• Closely matches the characteristics and performance of R404A, R507, R448 and R449
• Using R452A as a replacement results in time and cost savings during a retrofit
• R452A should only be liquid charged into a system to ensure correct refrigerant composition and system performance
• Systems operating on R452A may be compatible with R448A as an alternative when the full charge is replaced.

Features:

• GWP 45% lower than R404A
• GWP 40.5% higher than R448A
• Matches discharge temperature to R404A and R507
• Allows for use in new and existing equipment
• No TX valve change required
• Quick and easy retrofit option
• Can be topped up after leaks
• Compatible with existing equipment and lubricants

Applications:

Low and medium temperature direct expansion applications
including:

• Transport refrigeration including trucks, vans and reefer containers
• Commercial and industrial refrigeration
