Seltrade offers R-508B refrigerant gas, a high-performance, non-ozone-depleting HFC blend designed for ultra-low temperature refrigeration applications. As a direct replacement for R-13 and R-503, R-508B refrigerant gas is used in specialized cooling systems where consistent performance at extremely low temperatures is essential — including medical freezers, environmental test chambers, and pharmaceutical cold storage.

Key Features

Exceptional Ultra-Low Temperature Capability:R-508B is optimized for applications requiring temperatures down to -100°C (-148°F), making it ideal for cryogenic systems, vaccine storage, aerospace testing, and other critical cold chain environments.

Zero Ozone Depletion Potential:Formulated without chlorine, R-508B has an ODP of 0, providing an environmentally responsible alternative to CFC-based refrigerants such as R-13 and R-503, without compromising on cooling performance.

Safe and Non-Flammable:With an ASHRAE classification of A1, R-508B is non-toxic and non-flammable, offering a high level of operational safety in both commercial and industrial settings.

POE Lubricant CompatibilityR-508B refrigerant gas requires the use of polyolester (POE) lubricants, ensuring reliable oil return and compatibility in systems specifically designed for low-temperature HFC refrigerants.
