Shell & tube heat exchangers consist of a shell and a tube bundle inside. A tube bundle can have a form of a coil (like in JAD, S and H) or straight tubes (like in B, TI, EVO, REV and P). In most cases hot medium goes in tubes and cold medium in a shell. Tubular heat exchangers are welded and manufactured using stainless steel throughout which prevents risk of a leak and makes them resistant to corrosion. Thanks to many types and sizes shell & tube heat exchangers are ideal solutions for industrial purposes as well as in domestic heating systems.
