Specifically intended for application on refrigeration systems to transfer heat between high side liquid refrigerant and low side refrigerant vapor. This heat transfer may be desirable for several reasons:

• To raise the vapor temperature to prevent frosting or condensation on the suction line
• To evaporate any remaining liquid in the vapor stream to prevent possible compressor damage
• To subcool the liquid to prevent flash gas in the liquid line
• To increase system refrigerating capacity
