Products
Pressed steel radiators, assemblies and banks — manufactured to your drawing and specification.

Our flagship product — corrugated pressed-steel radiators for transformer oil cooling, built to your drawing.

Radiators built to non-standard dimensions and construction, entirely from customer drawings.

Complete radiators assembled from multiple panels, and radiator banks for larger cooling loads.

Individual corrugated radiator panels, supplied loose for assembly, repair or replacement.
Why Choose Us
Every radiator is tested with air and oil at 2.5 kg/cm² — above its 2 kg/cm² rated operating pressure — before it leaves the factory.
Panel size, OD, header length and flange specification are all set by your drawing or stated requirement — not a fixed catalogue.
Panel forming, welding, testing and painting all happen on our own factory floor in Jaipur, so quality checks travel with the unit at every stage.
48 mm, 58 mm, 75 mm and 90 mm OD panel types manufactured in-house, from single panels to complete multi-assembly banks.
A team of around 90 people, including a dedicated 4-member quality and engineering team, on a 2,800 sq. ft. production floor.
Supplying transformer manufacturers, OEMs and industrial buyers directly, with drawings and quotations handled by our own sales team.
Manufacturing
Our nine-stage production flow, from raw steel to a packed, dispatch-ready radiator.

Cold-rolled low-carbon steel (CRCA) sheet and mild-steel pipe are received and staged for panel pressing and header fabrication.

Sheet steel is corrugated and pressed into radiator fins on our roll-forming and spot-seam lines, to 0.8–0.9 mm panel thickness.

Formed panels are pressed and seam-welded on our spot-seam machine, then trimmed and checked for consistent profile before moving to assembly.

Panels are welded onto mild-steel top and bottom headers to build a complete radiator element, sized to the OD (48/58/75/90 mm) and length called for in the order.

Individual radiator elements are grouped into the finished assembly or bank configuration, with flanges (150 x 150 mm, 12/16/20 mm) fitted per the customer's drawing.

Each assembly is visually and dimensionally checked — panel alignment, weld seams and flange fit — before it goes for testing.

Radiators are submerged and pressure-tested with air and oil at 2.5 kg/cm² — above the 2 kg/cm² maximum operating pressure — to check every weld seam for leaks before it is approved for finishing.

Tested units are surface-prepared and finished with a red-oxide primer followed by a top coat of paint, applied by spray.

Finished radiators are packed in wooden crates with plastic protective wrapping (packing chargeable separately) ahead of dispatch.

Quality
Every radiator passes through these checks on our factory floor before it is approved for dispatch.

Incoming CRCA sheet and header pipe are checked before being released to the forming line.

Formed panels and headers are checked against the order drawing for panel size, OD and header length.

Panel-to-header and assembly welds are visually inspected for seam consistency before a unit proceeds to testing.

Each radiator is submerged in the test tank and pressurized with air and oil to 2.5 kg/cm² to confirm every seam holds under pressure.

Painted, finished units are given a final visual check for surface finish and completeness before packing. See the Manufacturing page for packaging and dispatch details.
Formal certifications are not yet listed — our quality process is built around pressure-testing every unit at 2.5 kg/cm² before dispatch. Contact us for test documentation on a specific order.
