Radiators
Oval-tube transformer radiators manufactured to CEI-EN 50216-6. 4 to 34 elements per radiator, heights from 800 mm to 3,500 mm. Approximately 30% greater heat dissipation than stamped plate alternatives.
About this product.
The Convett radiator is manufactured using oval-section tubes of high grade steel. Each element comprises nine tubes that are automatically welded and tested, attached to two pressed steel caps measuring 1.5 mm thick. Radiators can be composed of various numbers of elements, ranging from 4 to 34, with heights between 800 to 3,500 mm. Manufacturing follows CEI-EN 50216-6 standards.
The design enables excellent oil circulation without laminar movement risk and delivers high thermal efficiency. The relationship between the surfaces lapped by oil and air allows these radiators to achieve approximately 30% or greater heat dissipation compared to stamped plate alternatives.
