TECHPERT Process Industrieshas technical expertise in process and mechanical design of Heat Exchangers. We have design expertise in Heat Exchanger for specific customer applications to achieve desired output parameters. Our design and manufacturing is compliant with TEMA Standards. Our Heat Exchangers are ranging from 5 M3 to 5000 M3 heat transfer area with variable operating ranges. We design heat exchangers in various metal alloys.We have straight tube, U tube and other designs also.

Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls, either from tube side to shell side or vice versa. The fluids can be either liquids or gases on either the shell or the tube side. In order to transfer heat efficiently, a large heat transfer area should be used, leading to the use of many tubes. In this way, waste heat can be put to use. This is an efficient way to conserve energy.

Heat exchangers with only one phase (liquid or gas) on each side can be called one-phase or single-phase heat exchangers. Two-phase heat exchangers can be used to heat a liquid to boil it into a gas (vapour), sometimes called boilers, or to cool the vapours and condense it into a liquid (called condensers), with the phase change usually occurring on the shell side.. In large power plants with steam-driven turbines, shell-and-tube surface condensers are used to condense the exhaust steam exiting the turbine into condensate water which is recycled back to be turned into steam in the steam generator.

They are also used in liquid-cooled chillers for transferring heat between the refrigerant and the water in both the evaporator and condenser, and in air-cooled chillers for only the evaporator. They various applications in Food, Chemical, Power and Pharmaceutical Industry.
