R-508B Refrigerant Gas Supplier in Hyderabad. R-508B is the azeotropic ultra-low-temperature blend (R-23/R-116) that replaced the banned CFC R-13 and R-503 in cascade low stages. It boils at about −88 °C and, being azeotropic, charges without the glide a zeotropic blend brings.

Typical buyers: laboratory and pharmaceutical sites with ULT freezers and cascade chillers; environmental test-chamber builders and service firms; specialist industrial refrigeration contractors working below −60 °C across Telangana and AP.

We supply in original, factory-sealed packaging, sourced direct from Stallion. Safety Data Sheets and specifications are available on request, and we dispatch across India from Hyderabad.
