R32 (Difluoromethane, CAS 75-10-5) is a single-component HFC refrigerant with a GWP of 677 — significantly lower than R410A's GWP of 2,088. This makes R32 the preferred choice for new residential air conditioning and heat pump systems worldwide, especially in markets with strict F-Gas regulations.
As a China-based refrigerant exporter with 37 years of experience, Dalian Tongtai (TCoolGas) supplies R32 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.
Split systems, multi-split, VRF for homes and apartments.
Air-source and ground-source heat pump applications.
Light commercial air conditioning systems.
Lower GWP meets EU and global regulations.
