R507A is an azeotropic HFC blend of R125 and R143a (50/50 by weight) with zero ODP and a GWP of 3,985. Because it is truly azeotropic (no glide) it is preferred over R404A for low-temperature commercial refrigeration, ice machines, and transport refrigeration where consistent evaporating temperature matters.
As a China-based refrigerant exporter with 37 years of experience, Dalian Tongtai (TCoolGas) supplies R507A to 50+ countries with full SDS / TDS / COA per batch. We support mixed-SKU container consolidation and provide third-party re-test reports within 24 hours on request.
