RAD-TEK transformer radiators are manufactured according to EN 50216-06 and DIN 42559 standards. Our radiators are vacuum proof and able to withstand 1 Bar pressure at 100°C transformer oil.
The panel width of the radiators is 520 mm and the distance between the two panels is 45 mm. Generally radiator panel length varies between 800 - 3500 mm. The quantity of panels used in each radiator is generally ranging from 5 to 35. All types of radiators such as normal, corner-cut (left or right side), off-set, graded (swanneck) and slanted can be manufactured by RAD-TEK.
Radiator panels are manufactured from DIN 10130 DC01 CCR steel sheet with a thickness of 1.0mm, 1.2mm or 1.5mm. Radiators can also be manufactured from stainless steel, on request.
Our radiators are painted in accordance with corrosion protection standard of the EN ISO 12944. The inner and external surfaces of the radiators are cleaned before painting. External surfaces are cleaned from oil, dirt and rust in the special chemical baths. Radiators are also being phosphated in the zinc phosphate bath to ensure better adhesion of the painting.
The inner surfaces of radiators are coated with celerol equivalent painting resistant to transformer oil. The external surfaces are carefully painted by the well-trained and experienced painters by flooding method at the corrosion level in compliance with the instructions and the corrosion level requested by the customer. For high corrosion requirements, hot dip galvanization and e-coating (KTL) applications are also successfully performed before painting.
