Profile: Spreja Engineering specializes in offering stainless steel fabrication services, industrial tanks, industrial channels and refinery products. We provide fabrication machines, industrial fabrication machines, industrial fabrication equipments like fabricated aerator/mixer industrial tanks, plate flanges and swing hammer fibrizor. Our shell and tube condenser / heat exchanger is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. This type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed by several types of tubes such as plain & longitudinally finned tubes. Our tanks are available in round and square shapes.
