Brazed Plate or Shell & Tube Evaporators

Two styles of evaporators are commonly used in Advantage process liquid chillers. The evaporator is where the process water is cooled during the refrigerant-to-water heat exchanger portion of the chilling cycle.

• Brazed Plate Evaporators are used in most Advantage portable liquid chillers and smaller central liquid chillers. Their space efficient shape and high efficiency allows for compact machine design. The non-ferrous construction eliminates rusting and alternating plate design makes the brazed plate evaporator less susceptible to freeze damage when compared with shell and tube evaporators.
• Shell & Tube Evaporators are physically larger and heavier than brazed plate evaporators but are more tolerant of fluid contaminants.
