R454c is a low GWP, HFO-based (hydrofluoroolefin) refrigerant with the optimum balance of properties to replace R404a ,R407C and R22 refrigerants in medium- and low-temperature direct expansion applications. It offers the performance close to the refrigerants it is designed to replace which makes R454c easy and cost-effective to apply to new equipment with minor modifications.

With a GWP of 146, R454c falls under the 150-threshold value in the F-Gas regulation 517/2014 and Ecodesign requirements, thus being particularly suited for commercial and industrial refrigeration systems

APPLICATIONS:

  • Low- and medium temperature commercial and industrial refrigeration systems formerly designed for R404a, R407C or R22
  • Condensing units, cold stores, walk-in coolers and freezers
  • Ideally suitable for hermetically-sealed refrigeration systems
  • Easily convertible from R404a, R407C and R22 design with minimal changes

PERFORMANCE RELATIVE TO R404A:

  • 10% less capacity
  • 7.5% higher COP (coefficient of performance)
  • 25% reduction in mass flow
  • Lower compressor suction and discharge pressures

ENVIRONMENTAL BENEFITS:

  • <150 GWP (96 % reduction versus R404a)
  • Meets F-Gas and Ecodesign GWP requirements
  • Zero ozone depletion
  • Non-toxic and mildly flammable
