Operating Uttarakhand’s premier dedicated hydrostatic pressure testing and chemical refilling facility in Haldwani. We service industrial fleets, hospitality properties, hospitals, and educational institutions across Kumaun and Garhwal with rapid 24-hour turnaround, calibrated nitrogen pressurization, and official statutory test certificates.
Never risk lives with counterfeit or roadside refilling. Every cylinder passing through our Haldwani lab undergoes rigorous mechanical inspection:
Safe depressurization in our exhaust hood. Residual powders are cleared and spent gases environmentally recaptured.
Endoscopic internal lighting to inspect for wall pitting, rust scaling, thread damage, and internal lining corrosion.
Water jacket hydrostatic test to 35 bar (or 250 bar for CO₂). Verifies cylinder expansion does not exceed permanent set limits.
Hot air internal bake-out to eliminate moisture entirely, ensuring powder does not lump or cake over time.
Precision digital gravimetric filling using certified Mono Ammonium Phosphate (MAP 50% / 90%), AFFF foam, or liquid CO₂.
Pressurization with ultra-pure dry nitrogen to 15 kg/cm² operating threshold. New brass valves and rubber O-rings fitted.
Total submersion in illuminated water testing tank for 15 minutes to confirm zero microscopic valve or weld leaks.
Punch-coded inspection maintenance tag attached with tare weight, net weight, test date, and formal Test Certificate issued.
We provide doorstep collection vans and standby loaner extinguishers so your premises remain 100% fire-protected during servicing.
