We manufacture Pressed Steel Radiators for Power and Distribution Transformer Cooling. Our products include,
(FA type Radiators with flanges and elements having different lengths; EN 50216:6-2002).
standard products, we also design and manufacture customized Pressed
Steel Radiators, Tanks & Panels to meet clients' special
standard Pressed Steel Radiators, Tanks & Panels meet IEEMA (Indian
Electrical Equipment Manufacturers Association) specifications and BSEN
50216 (previously DIN 42559) standard.
PRINCIPLE: Once our customer must always be our satisfied customer.
Those who trusted us with one order have remained with us ever after.
(FA type Radiators with flanges and elements having different lengths. EN 50216:6-2002).
Raw Material and Process Flow
Internal Surface Preparation
internal surface of the Radiators are washed and cleaned to avoid
transformer oil contamination with oil for transformers according to
ISO 4406 and coated (flush coating) with varnish. Internal surface
painting can also be arranged as per specific purchaser requirements.
External Surface Preparation
standard products are de-greased prior to painting with two coats of
zinc chromate red oxide primer to prevent corrosion. Finished painting
is done by enamel / epoxy paint or as per customer specification. Sand
/ quartz / grit blasting as per customer requirement. We have a surface
treatment section equipped with steel shot blasting machine and
Radiators are pressure tested individually for leak proofness, under
water at an air pressure of 200 kPa (2kg/ cm2) for 30 minutes.
(Standard water immersing test). Compliance is checked by immersing the
Radiators in a water filled tank. Randomly selected Radiators from all
consignments goes through hot oil test. (the Radiators are filled with
transformer oil at a temperature of 600 C and kept at a pressure of
200 kPa ( 2.0394 kgf/ cm2) for 3 Hours to ensure no oil leaks.
External surfaces of the Radiators are checked for deformations.
I. Dimension and tolerances check
II. Visual inspection for welding
III. Internal surface check for presence of any foreign bodies or contamination
IV. Paint peel off test (inspection of external paint).
Preparation for Transportation and Storage
Our Quality Control Division carries out one final check for radiator cleanness, foreign bodies and other contamination. The Radiators passed trough a stringent checking system developed by our qualified engineers and technicians.
Flanges are covered to prevent the ingress of contamination during transportation or storage. We take all possible measures to avoid mechanical damages to the Radiators.
With our radiators, we try to serve our customers to reduce their costs through savings on fluids due to our superior heat transfer, and the reduction of number of elements per radiators per transformer (reducing labor, handling, etc.)
