DewCheck is DewGas’s product traceability platform. Every DewGas cylinder carries a unique QR code linked to its batch test results, Certificate of Analysis, Safety Data Sheet, and compliance documents — accessible instantly from any smartphone.
Scan the DewCheck QR code on the cylinder’s label using any smartphone camera. No app required. The scan opens a verification page with the cylinder’s authenticity status, product details, and batch documentation.
Product authenticity, batch number, manufacturing and filling details, product specifications, Certificate of Analysis, Safety Data Sheet, quality certifications, and compliance documents — all downloadable in PDF.
AHRI 700 is the industry standard published by the Air-Conditioning, Heating, and Refrigeration Institute that defines purity specifications for refrigerants — covering moisture, acidity, non-condensable gases, and contaminants. It is the benchmark used by equipment manufacturers and quality-focused procurement teams globally.
Yes. The COA for your cylinder’s batch is available as a downloadable PDF from the DewCheck verification page, suitable for procurement audits and regulatory records.
Directly from the DewCheck scan page. SDS documents are also available by product in our Resource Centre.
Check that the label is undamaged and your camera is in focus. If the code is unreadable, do not use the cylinder until you have confirmed authenticity. Contact our quality team with the batch number printed on the cylinder and we will verify it manually.
Every batch is tested in our in-house laboratory using Gas Chromatography and Karl Fischer Coulometry before any cylinder is filled. Batches that do not meet AHRI 700 specifications are not approved for release. The verified results are linked to each batch record in DewCheck — so what you access via QR is the actual data from your specific batch.
Whether you are specifying AC refrigerant gas for a new OEM production line, procuring refrigerant gas for air conditioning maintenance across a commercial property portfolio, or sourcing bulk supply for a data centre cooling project, the quality and regulatory standing of your refrigerant directly affects system performance, equipment lifespan, and compliance standing. The AC refrigerant gas in any installation must match the compressor rating precisely. The wrong refrigerant gas type causes compressor damage, performance loss, and warranty avoidance.
DewGas is among India’s established air conditioner cooling gas manufacturers, operating two AHRI 700 certified filling facilities in Hisar, Haryana and Sri City, Andhra Pradesh. Every batch is tested in our in-house lab, and every cylinder is QR-linked to its batch certificate for independent verification.
There are different types of refrigerants used across air conditioning and commercial cooling in India, from AC refrigerant gas for split systems to natural refrigerants for industrial process cooling. Each refrigeration gas type carries a distinct GWP, ODP, flammability classification, and regulatory standing.
HCFCs (R-22): The legacy refrigerant gas used in air conditioners manufactured before 2020. Still legally available for servicing existing equipment under India’s HCFC Phase-out Management Plan, but not permitted for new systems.
HFCs (R-32, R-410A, R-134a, R-407C): The dominant AC refrigerant gas in India today, used across residential split systems, commercial HVAC, chillers, and automotive AC. R-32 is the preferred refrigerant gas for air conditioning in new residential and light-commercial systems, offering lower GWP (675), better energy efficiency, and reduced charge mass compared to R-410A (GWP 2,088). The refrigerant gas in AC units installed since 2018 is predominantly R-32 or R-410A. Each refrigeration gas type here is AHRI 700 certified and batch-tested by DewGas.
HFOs and blends (R-454B, R-466A): Lower-GWP alternatives entering the market ahead of Phase-III HFC reduction targets. Relevant for OEMs designing equipment for 10-plus year market cycles.
Natural refrigerants (R-290, R-717): Very low GWP, used in specific commercial refrigeration and industrial process cooling. A3 and B2L flammability classifications require segregated handling infrastructure.
The right refrigeration gas type for any application is defined first by equipment specification, then regulatory trajectory and supply reliability.
For OEM manufacturers, evaluating AC refrigerant gas options early in the specification process prevents costly retrofits when regulatory phase-downs take effect. The refrigerant gas for air conditioning systems must align with compressor ratings and product lifecycle plans. India’s HFC phase-down under the Kigali Amendment begins in 2032. Specifying high-GWP AC refrigerant gas for production runs with 5 to 10 year cycles carries regulatory risk that should be built into decisions today. Partnering with certified air conditioner cooling gas manufacturers ensures supply is documented, authorised, and traceable.
For commercial HVAC contractors, the refrigerant gas in AC or chiller systems must be consistently available at certified purity. India’s peak ambient temperatures (35-48°C) make purity a baseline requirement: refrigerant gas used in air conditioners outside AHRI 700 tolerances in high-ambient conditions causes accelerated compressor wear. Confirming the refrigerant gas in AC units before topping up or retrofitting prevents cross-contamination failures.
For data centre operators, supply continuity and batch documentation from a certified refrigerant cooling gas supplier are the primary procurement criteria. Every refrigerant gas used in air conditioners or precision cooling systems supplied by DewGas is verified at the batch level before dispatch.
Among air conditioner cooling gas manufacturers in India, DewGas operates with in-house lab testing, QR-based traceability, and production across two certified facilities. As refrigerant cooling gas manufacturers supplying cylinder and bulk formats, DewGas serves OEM production lines, national distributors, and commercial contractors. Our two-facility model gives customers supply continuity that single-location air conditioner cooling gas manufacturers cannot match during peak season. Every batch of refrigerant gas for air conditioning, commercial HVAC, and industrial cooling is tested against AHRI 700 purity standards, with documentation available on demand.
DewGas works with an authorised network of refrigerant gas dealers and refrigerant cooling gas manufacturers across India covering metro, Tier-2, and industrial belt markets. Whether you are procuring through a regional refrigerant cooling gas dealer, engaging a refrigerant cooling gas supplier for ongoing contracts, or need a dedicated refrigerant cooling gas provider for OEM production supply, every partner carries AHRI 700 certified product with full batch documentation. As refrigerant cooling gas manufacturers, DewGas also supplies large OEMs and distributors directly. To find refrigerant cooling gas dealers in India by state or city, use the DewGas dealer locator. For a verified refrigerant cooling gas provider or additional refrigerant gas dealers in your area, contact our sales team to be connected to the right authorised refrigerant cooling gas provider in your region. A complete list of refrigerant cooling gas dealers in India is available through our online locator.
