Ten controlled stages take raw copper and aluminium to a fully tested, dispatch-ready coil — with a quality checkpoint between each one.
The difference between a coil that hits its numbers and one that doesn't is decided on the factory floor — in the purity of the copper, the tightness of the tube-to-fin bond and the discipline of the brazing.
We control every one of those variables, then prove the result with 35-bar pressure and leak testing on every single unit. Nothing ships on hope.

Certified 99.9% copper tube and aluminium fin stock arrive with material documentation and are checked before entering production.
Tubes are cut, cleaned and formed to length — the foundation of every heat-transfer circuit.
Fins are precision-punched on a forming press for maximum surface area and consistent spacing.
Tubes are mechanically expanded into the fin pack, creating a permanent, gap-free thermal bond — the single biggest driver of coil performance.
Return bends, headers and joints are brazed clean and leak-proof using silver / phos-copper alloys.
Every coil is submerged or gas-tested to detect the smallest leak before it moves on.
Coils are pressure-tested at 35 bar to guarantee they hold charge under real operating loads.
Dimensions, fin condition, joints and finish are inspected against the drawing at a dedicated checkpoint.
Coils are protected, capped and crated to survive transit and arrive site-ready.
Finished coils ship on committed lead times, pan-India, with documentation.
