Below is a list of Plate and Frame Heat Exchangers manufacturers from Windsor, Connecticut. Plate and frame heat exchangers transfer heat from one liquid to another through corrugated plates, fastened together and mounted on a frame. Within plate and frame heat exchangers, hot and cold fluids run separate from each other in different chambers. Plate exchangers are used widely in water heating in domestic, commercial and industrial settings due to the energy efficiency of the process, as well as in cooling and refrigeration processes.
