Quality
Premium Raw Material Selection
We use nominal 1.0 mm / 1.2 mm thickness CRCA steel conforming to Grade D of IS:513 for our radiator elements, along with ERW/HFIW header pipes to IS:1239, structural steel plate to Grade E250 of IS:2062 for step flanges and lifting lugs, and Teflon washers for air release and drain plugs. Every material is selected and tested before production, so each radiator can handle heat, pressure, and daily use. Our focus on quality materials helps us deliver products you can trust.
Advanced Manufacturing Technology
Every radiator moves through a controlled, multi-stage process — cutting & forming, welding quality checks, assembly & fit-up, surface preparation, leak testing, final dimensional checks, painting & coating, and final quality approval before packing & dispatch. Each stage is checked by trained experts to make sure the quality stays high, reducing errors and improving the final product finish. This technology also helps the radiators last longer in tough conditions.
High Mechanical Strength
Our radiators are manufactured in widths up to 520 mm and lengths from 600 mm to 4000 mm, using 1 mm and 1.2 mm thickness CRCA steel along with 12 mm, 16 mm, and 18 mm thick structural steel step flanges. Each radiator is designed to handle heavy pressure and high temperature without losing its shape. This strong build helps transformers work safely for many years. You can trust our products for long-lasting performance.
International Quality Compliance
Every component of our radiators — from the CRCA steel elements to header pipes, flanges, bracing bars, and lifting lugs — is manufactured to Indian Standard (IS) specifications, including IS:513, IS:1239, IS:2062, and IS:7283. Our team checks every part properly, so each product works long and safely, matching demanding industry requirements.
Long Service Life
Every radiator is shot blast cleaned and coated externally with Red Oxide Zinc Chromate Primer, MIO, and Enamel / Epoxy / PU finish, giving a total dry film thickness of 70–350 microns, with a heat-resistant internal varnish coating. Options such as Zinc Rich Primer, Epoxy/Polyurethane finish, spray galvanizing, and hot-dip galvanizing are also available. This makes them reliable for power plants, industries, and heavy-duty work, keeping them working smoothly for many years.
Optimized Heat Dissipation
Our radiators are rated using a detailed heat dissipation chart for the 520 mm width series, covering ONAN and ONAF cooling at oil excess temperatures from 35°C to 60°C. This keeps your system stable and strong even during long and heavy operations. Better cooling means longer transformer life and smooth performance in every condition.
Technical Specifications
We manufacture transformer radiators in widths up to 520 mm, lengths from 600 mm to 4000 mm, and thicknesses of 1 mm and 1.2 mm CRCA steel. Every part — from header pipes and end plates to step flanges, bracing bars, and lifting lugs — is built to Indian Standard (IS) specifications, and each radiator is finished with a total dry film paint thickness of 70–350 microns for long-term protection.
