Characteristics:

• Non-ozone depleting 
• HFC refrigerant
• Designed for the replacement of R22 in low and medium temperature applications
• R438A offers similar performance to R22 usually without the need for modification to existing equipment
• Kirby recommends alternative refrigerants with substantially lower GWP

Applications:

Low and medium temperature applications including:

• Low and medium temperature applications including
  • Low and medium temperature refrigeration
  • Air conditioning system
  • DX chillers  

Performance:

• Capacity and energy efficiency in low and medium temperature tends to equal R22
• POE oil is recommended 
• Must be charged from the liquid phase
• Non-flammable
• Allows for use of existing equipment 
• Matches R22 performance and efficiency 

Physical Properties:

• GWP 3985
• Boiling Point at -43°C
