From food cold chains and pharmaceutical storage to automotive manufacturing and data centre cooling, we supply AHRI 700 certified refrigerant gas with the quality, traceability, and supply reliability that demanding operations require.
From the production line to the cold room, from the automotive bay to the data centre floor, we supply certified refrigerant gas across every industry where cooling is mission-critical.
HVAC contractors, system integrators, and service engineers depend on a consistent, quality-assured supply of air conditioning refrigerant gas across a range of system platforms, from legacy retrofits to modern inverter AC and VRF installations. We supply R-32, R-410A, and R-407C for new systems, and R-438A as a certified drop-in retrofit for existing R-22 equipment with no system reclassification required.
Automotive AC systems, from passenger cars to commercial buses and fleet vehicles, require refrigerant gas that meets exacting OEM specifications batch after batch. We supply R-134a for conventional automotive AC systems and HC Blend for applications where hydrocarbon refrigerants are approved, both manufactured to AHRI 700 purity standards with batch traceability.
Data centre precision cooling and fire suppression are both mission-critical — a failure in either means downtime in a facility where every second counts. We supply cooling refrigerants for CRAC and precision air conditioning units, as well as HFC-227ea and FK-5-1-12 clean agent fire suppression for server rooms, control rooms, and critical electrical infrastructure, achieving extinguishing concentrations in under 10 seconds with zero residue.
Food processing and cold chain operations face strict temperature control requirements and regulatory scrutiny. We supply food processing refrigeration gas for processing facilities, cold rooms, display cabinets, and transport refrigeration, with AHRI 700 certified purity and batch-level traceability that supports food safety audits.
Pharmaceutical manufacturing, laboratory storage, and biomedical facilities require refrigerant gas that meets the highest purity and documentation standards. We supply AHRI 700 certified refrigerants for pharmaceutical cold rooms, medical freezers, and laboratory temperature control, with batch certificates and QR-based traceability to support GMP compliance and regulatory submissions.
Temperature-controlled logistics, from refrigerated vehicles and cold storage warehouses to distribution hubs and cross-dock facilities, depend on consistent refrigerant supply across the entire chain. We supply cold chain refrigeration gas for both transport and static refrigeration applications, with purity-certified products and reliable supply from two strategically located filling facilities across India.
Hospital refrigeration covers blood bank systems, vaccine storage, laboratory freezers, and pharmaceutical cold rooms, all operating under strict regulatory requirements with zero tolerance for cooling failure. We supply healthcare refrigeration gas solutions with AHRI 700 certified purity and full batch traceability, supporting the documentation requirements of hospital accreditation, drug storage audits, and infection control standards.
Railway coach air conditioning and metro rolling stock operate continuously in high-ambient conditions across India's climate zones, demanding refrigerant gas that performs without compromise. We supply R-407C and R-134a for rail AC systems, with a proven supply record that includes Indian Railways and Delhi Metro Rail Corporation.
Aerospace ground support equipment, hangar cooling, and avionics protection facilities require both precision refrigerant supply and fire suppression certified to international safety standards. We supply FK-5-1-12 and HFC-227ea clean agent fire suppression for aerospace facilities and critical control environments, with a supply track record that includes the Indian Air Force.
Defence installations, naval vessels, and military control environments combine high-ambient operational demands with the strictest safety and fire protection requirements. We supply cooling refrigerants and clean agent fire suppression solutions for defence applications, with supply experience covering the Indian Coast Guard and Indian Air Force.
Electronics manufacturing facilities, clean rooms, and electrical control infrastructure require precise process cooling and rapid-response fire suppression for sensitive equipment. We supply industrial cooling refrigerants for electronics production environments, and HFC-227ea and FK-5-1-12 clean agents for electrical cabinets, UPS rooms, and control facilities, leaving zero residue on discharge.
Chemical processing plants and large-scale industrial cooling systems operate under high thermal loads in demanding ambient conditions, requiring refrigerant gas with consistent purity and dependable bulk supply. We supply R-290, R-407C, and R-404A for industrial process cooling and chiller applications, with ISO tank and tonner formats available for large-volume procurement.
Industrial chillers, process cooling systems, and climate-controlled production environments depend on consistent refrigerant quality and uninterrupted supply. We supply industrial cooling gas solutions for manufacturing plants across sectors, including R-438A as a certified drop-in retrofit for facilities still operating R-22 equipment, with no system reclassification required.
Quality and supply are not separate commitments at DewGas — they are built into the same process.
Every product is filled from batches tested and certified to AHRI 700 standards. You receive a purity certificate, not a promise.
Scan the QR code on any DewGas cylinder to verify batch origin, test results, and fill date. Traceability you can show your auditor.
Our Hisar and Sri City facilities serve North and South India respectively, so supply disruptions in one region do not become your problem.
Our team understands refrigerant applications across industries. When a specification or transition challenge arises, we work through it with you.
R-438A is a certified drop-in retrofit for existing R-22 systems across air conditioning, industrial, and transport applications. It has similar pressure-temperature characteristics to R-22, requires no safety reclassification of the equipment, and is available in AHRI 700 certified quality with full batch traceability.
R-32 is the primary recommendation for new residential and commercial AC installations. With a GWP of 675, it offers significantly lower environmental impact than R-410A while delivering strong energy efficiency. It is compatible with inverter AC systems, fixed-speed units, dehumidifiers, and heat pumps.
Yes. We supply R-134a for conventional automotive air conditioning systems, used in passenger cars, buses, and commercial fleets.
