A Heat Exchanger Unit is a device used to transfer thermal energy (heat) between two or more fluids. Heat exchangers are used in a wide variety of applications, such as heating and cooling of buildings, industrial processes, and power generation.
The heat exchanger unit essentially consists of heat exchangers such as Plate Heat Exchanger, Shell and Plate Heat Exchanger, or other counterpart, a circulating pump, a fluid make-up pump, thermometers, a filter, sensors, a pipeline and valves. It is also possible to design a temperature control system, pressure stabilization system, variable-frequency controller, heat metering and communication controller, etc. according to the client`s requirements.
Big advantage of heat exchanger unit is that, by adopting a modularized structure, it maximizes each component`s function to the most. The precise control for heat exchange process also saves time and efforts for maintenance and installation.
Feature is that intelligent control, excellently energy-saving, high automation and easy to operate, high cost performance and wide application.
