Stainless steel exchange coil

corrosion-resistant

The wide range of product portfolio of coils with different tube diameters, tube patterns, fin profiles, materials and options allows us to customise our coils for any specific application and fluids: air heaters, air coolers, condensers and evaporators for HVAC and various industrial applications. Kelvion heat exchanger coils are manufactured with copper or stainless steel tubes and aluminium or copper fins. Design and application How are Coils constructed - and how do they work? The fins are equipped with special profiles developed at our R&D department enhancing heat transfer and keeping pressure drop at a moderate level. The customised fin spacing is achieved by collars which also provide the contact between the fin block and the tubes. Mechanical expansion of the tubes guarantees a perfect bond between the fins and the tubes leading to maximum heat transfer between both fluids. Several tubes are interconnected via brazed / welded return bends forming the circuits of the coil, which are provided with the working fluid by brazed tubular headers. All coils are tested for leaks after completion.
