R123 is a low-pressure refrigerant primarily used in large chillers. It offers low GWP and low ODP but is categorized as B1 due to toxicity concerns. As an HCFC, it is being phased out.

Key Properties of R123 Refrigerant:

• Application: Used in centrifugal chillers in large HVAC systems
• Type: HCFC
• Chemical Composition: 2,2-Dichloro-1,1,1-trifluoroethane
• Form: Liquid/Gas
• Brands: Kalton
• Appearance: Colorless
• ASHRAE Safety Class: B1 (low toxicity)
• Flammability: Non-flammable
• GWP: ~77
• ODP: 0.012
• Purity: ≥99.9% Min.
• Packaging: On Special Request

R123 remains a viable option in older chiller systems, but its phase-out requires considering alternative refrigerants for long-term sustainability.
