Seltrade offers R-402A refrigerant gas, a robust HCFC blend designed to restore and enhance performance in older low- and medium-temperature refrigeration systems. As a retrofit option for R-502, R-402A refrigerant gas delivers strong cooling efficiency and is well-suited for applications such as ice machines, refrigerated display cases, cold rooms, and food processing equipment.

Key Features

Optimized R-502 Retrofit: R-402A is formulated to closely align with the capacity and pressure characteristics of R-502, making it an effective choice for upgrading legacy systems without significant performance loss.

Wide-Ranging Application Suitability:From food storage to refrigerated transport, R-402A operates efficiently across a broad temperature spectrum, with strong cooling performance even in environments requiring temperatures as low as -40°F.

Oil System Adaptability:For best results, R-402A refrigerant gas is used with alkylbenzene (AB) oil. Systems previously using mineral oil may require partial or full oil replacement, depending on operating conditions and equipment design.

Moderate Temperature Glide:With an evaporator glide of around 10°F, system tuning may be necessary to optimize refrigerant distribution and achieve consistent cooling performance in retrofitted systems.
