Evaporator BL200 Plate Heat Exchangers for Evaporation 3" NPT R22 75/75mm

In addition to the compressor and expansion valve, the basic thermal equipment of the refrigeration unit must equip with basic heat exchangers—condensers and evaporators. Alfa Heating Evaporator device is used in most advantage portable liquid chillers and smaller central liquid chillers. Their space-efficient shape and high efficiency allow for compact machine design. The non-ferrous construction eliminates rusting and alternating plate design makes the brazed plate evaporators less susceptible to freeze damage when compared with shell and tube evaporators.
