In a commodity-driven refrigerant market, quality claims are easy to make and hard to verify. Adulterated or off-spec cylinders enter supply chains through informal channels — and the consequences show up as compressor failures, underperforming systems, and failed audits.
DewGas built DewCheck because quality should be something you can see, not something you are asked to trust. Every batch is tested in our in-house laboratory against AHRI 700 standards before filling. DewCheck links that verified data directly to the cylinder in your hand — via QR code, instantly.
Five-Step Quality Testing Process
Using a Bromothymol Blue indicator test, we verify that no residual hydrochloric acid is present in the refrigerant. This critical test helps protect system components from corrosion, ensuring only acid-free batches proceed further.
We measure moisture using Karl Fischer Coulometry in triplicate to ensure highly accurate results. Moisture levels are maintained well below the stringent AHRI 700 limit of 10 ppm, helping prevent ice formation, corrosion, and reduced system efficiency.
Specialised gas chromatography identifies unwanted gases and non-condensables that can increase system pressure, reduce cooling efficiency, and raise energy consumption. Every batch is screened to ensure reliable, consistent performance in real-world operating conditions.
One scan gives you the complete quality and compliance record for your cylinder’s batch — everything you need to verify, document, and report with confidence.
DewGas operates a fully equipped laboratory at our Hisar facility. Every batch — across both filling facilities — is tested here before release. No batch skips the process. Our equipment includes Gas Chromatography for purity and composition analysis, and Karl Fischer Coulometry for precise moisture measurement, both in line with AHRI 700 methodology.
As lower-GWP refrigerants increasingly carry A2L or A3 flammability classifications, segregation during filling, storage, and dispatch is non-negotiable. Our facilities maintain dedicated infrastructure for flammable and non-flammable refrigerants — preventing cross-contamination and ensuring safe handling at every stage.
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.
Stop relying on claims. Start sourcing refrigerants with verified purity, batch-level documentation, and full traceability — backed by DewCheck.
