SWEP and Alfa Laval plate heat exchangers for all industries. Applications: chiller heat exchangers, swimming pool heat exchangers, VRF heat exchangers, dryer heat exchangers, air-to-water pump heat exchangers or other ...types, etc. The operating principle of a heat exchanger is based on thermodynamics: it allows the transfer of thermal energy from a warmer fluid to a colder one without the two fluids physically mixing. For special applications, heat exchanger sizing can be used. Contact DTN Group for sizing or unpublished models! Mai mult
