Cetecoil - Shell and tube heat exchanger Stainless steel / Carbon steel - Alfa Laval - #1

Text version of the page

Shell and tube heat exchanger Stainless steel / Carbon steel Cetecoil® Cetecoil® is the collective name for a range of heat exchangers with tubes made of acid proof stainless steel and suitable for many different media, such as steam, domestic hot water, heating water and hot oil. When operating with steam, the Cetecoil is a very efficient condensate cooler. The Cetecoil heat exchanger is also very well-suited for use in systems in which continuous operation at high water velocities is required. High pressures and temperatures Cetecoil heat exchangers have no gaskets and can operate at high pressures and high temperatures, even when handling media that are subject to sudden and big temperature variations, such as in steam and refrigeration systems. In their standard design, Cetecoil heat exchangers are rated for pressures up to 25 bar and temperatures up to 300°C. Flexible range Cetecoil heat exchangers are manufactured in three different basic versions as regards materials and pressures, and these are designated R, S and E. All versions have stainless steel tubes. Every basic version is manufactured in a number of sizes and different thermal lengths. This wide range makes it simple to order a suitable Cetecoil heat exchanger for virtually any operating conditions. For higher capacities, several heat exchangers can be connected in parallel or in series. Unique design with patented tubes The stainless steel tubes are cross-rilled. This improves the thermal properties of the tube, both on the inside and on the outside, which contributes towards a very high heat transfer rate. The performance of the heat exchanger is determined by the number of tubes and the tube length. The tubes are wound into a spiral around a central core. Each end is then secured into the tube plate. The tubes form together with the collecting chambers the ’coil’ which is welded to the surrounding shell. In this design, the strength of an all-welded design is combined with high elasticity for absorbing thermal expansion. The upright position also means that Cetecoil needs a minimum of space.
