Freon™ 123 (R-123) Refrigerant

A Refrigerant for Efficient Cooling in Large Buildings

Large buildings often depend on centrifugal chillers for cooling. These systems use a vapor compression cycle to remove heat from the liquid that moves through a heat exchanger, and sends the waste heat through a second water loop cooled by a cooling tower. The chilled water cools and dehumidifies air in commercial, industrial, and institutional facilities.

For years, centrifugal chillers used R-11 refrigerant. But as global regulatory mandates require the phase-out of R-11, many chillers use Freon™ 123 (R-123) refrigerant as an alternative because of its low ozone depleting properties.

The thermodynamic and physical properties of Freon™ 123 make it efficient and safe for use as a replacement in new systems and as a retrofit in installed equipment. Retrofitted centrifugal chillers often need system modifications to increase capacity or avoid material incompatibility. Consult with your original equipment manufacturer (OEM) for specific guidance.

Features and Benefits

Freon™ 123 refrigerant is a hydrochlorofluorocarbon (HCFC) replacement for the chlorofluorocarbon (CFC) R-11 in centrifugal chillers.

Benefits of using Freon™ 123 include:

  • Low ozone depletion and excellent environmental properties
  • Proven R-11 replacement in chiller systems worldwide
  • OEM acceptance

Regulations on the long-term use of refrigerants vary by region and application, and may change over time. For the latest information, please visit the Regulations page.
