Transformer Radiator Solutions

Key radiator types we manufacture for transformers and allied equipment.

Welded Type Radiators

Heavy-duty welded radiators engineered for reliable cooling on power and distribution transformers.

Flanged Type Radiators

Flanged radiators that allow easy mounting, removal and maintenance on the transformer tank.

Offset Radiators

Radiator assemblies designed to suit restricted clearances and special layouts.

Swan Neck Radiators

Curved swan-neck radiators that provide flexible oil connection routing and positioning.

Radiators With Graded Elements

Graded fin lengths that help optimise heat dissipation and oil circulation across the assembly.

Radiators With Sloped Elements

Sloped element radiators engineered for better oil draining and cooling characteristics.

Radiators With Multiple Inlet & Outlets

Multi-inlet and outlet radiators that serve higher ratings and complex transformer designs.

Transformer Radiators

TRANS-VOLT Steel Pressed Radiators

TRANS-VOLT manufactures pressed steel radiators for power and distribution transformers, designed for efficient oil cooling and long, reliable service. Our radiators are used on transformers, rectifiers, reactors and other oil-cooled equipment across a wide range of ratings.

TRANS-VOLT transformer radiators

We boost the energy by cooling the temperature.

The plant has a capacity to manufacture radiators with fin widths of 226 mm, 300 mm and 520 mm. Fins are manufactured with a pitch of 50 mm, in lengths from 400 mm to 4000 mm (in steps of 100 mm) and assemblies ranging from 2 to 30 fins as per customer requirements.

Aesthetics and Surface Protection

Each radiator is finished with a robust internal and external coating system designed to protect against corrosion and extend service life.

  • Inner surface coated with approximately 10 micron thick varnish to Class "A" as per IS 10026 – 1983.
  • Outer surface blast-cleaned and spray-painted with primer and two coats of high-grade red oxide zinc-chrome as per IS 2074.
  • Final finish paint supplied as per client requirements; alternate primer and finish systems available on request.

Quality Assurance & Testing

The company is strongly committed to quality and customer service, with a clear aim to be regarded as the best in its business. Every radiator is manufactured under controlled processes and individually tested.

  • Comprehensive dimensional checks for each radiator assembly.
  • Each radiator individually air-pressure tested at approx. 2.5 kg/cm2 under water for at least 30 minutes.
  • Testing practices aligned with relevant industry standards such as IEEMA specifications.
