Seltrade offers R-402B refrigerant gas, a high-efficiency HCFC blend designed as a retrofit solution for low- and medium-temperature refrigeration systems originally using R-502. Developed to deliver improved performance in demanding environments, R-402B refrigerant gas is ideal for commercial freezers, cold storage units, refrigerated transport, and supermarket display cases

Key Features

Optimized R-502 Retrofit: R-402B is specifically formulated to closely match and often exceed the cooling performance of R-502, making it an ideal retrofit choice for maintaining system reliability in older refrigeration equipment.

Superior Low-Temperature Performance:Engineered for low- and medium-temperature applications, R-402B refrigerant gas maintains excellent cooling capacity even at evaporator temperatures as low as -40°F, supporting efficient operation in high-demand settings.

Enhanced Oil Compatibility:R-402B is typically used with alkylbenzene (AB) oil for best results, although partial or full conversion from mineral oil is often required depending on system conditions and temperature range.

Moderate Temperature Glide:With a temperature glide of approximately 9–10°F, R-402B requires appropriate system tuning to ensure balanced and efficient refrigerant evaporation, especially in retrofitted systems.
