Leading technology for individual solutions THE ELLIPTICAL FIN TUBE – REINVENTED Inspired by concept of efficiency – Making proven solutions even better The hot dip galvanized elliptical fin tube – with its favorable flow characteristics – has been proving its marketability for decades and will continue to play an outstanding role on the heat exchanger market in the future. Wherever heat transfer is needed in industrial production processes, the elliptical fin tube has demonstrated its high efficiency in areas of application that include the following: • Refineries • etrochemical industry P • Steel mills and the rest of the steel industry • atural-gas facilities N • Power plants • Paper industry • Textile industry Experience, knowledge and precision Kelvion has conducted development work in collaboration with the Westphalian University of Applied Sciences in Gelsenkirchen, Germany. Their work has shown that the elliptical fin tube still offered room for optimization. With the method of numerical flow simulation (CFD) we have e.g. investigated the effects of new turbulators on the fins. The results were validated by wind tunnel measurements. A patent was applied for the new invention which is called: CW Tube High efficiency • n heat transfer i • flow performance results in a product with - low operating expenses - less material usage - low CO2 -emissions

Lighter, higher efficiency and more silent – The CW Tube redefines standards As a result of reduction in specific air-side pressure drop, while achieving a higher heat transfer coefficient at the same time, the CW Tube reaches the following: Power consumption Material usage Corrosion resistance Noise level This pays off in many respects: Both investment and operating costs can be saved. In parallel the environment will be protected by reduction of CO2 - and noise emission. Thermal performance Carbon footprint • up to 25 % less requirement of heat exchanger tubes • up to 30 % less electrical...
