Customized for your particular requirements and applications
The wide range of product portfolio with different tube diameters, tube patterns, fin profiles, materials and options allows us to customize 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 tubes and aluminum or copper fins. 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 customized 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 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. The thermodynamic design is performed with an in-house developed selection software which is based on the measurements in our laboratory conform to DIN EN1216. Retesting on a regular basis supports quality control of our coils. The wide range of our product portfolio with diverse options allows the design of customized coils leading to cost-optimized and energy efficient products. Short delivery times and an excellent service support completes satisfaction of our demanding customers.
