Process chillers have two sides: the process water side, and the refrigerant gas side. The heat is picked up from the process on the process water side, and gets transferred to the refrigerant side, where it is removed to air or water. In between these two sides is the evaporator, sometimes called the chiller barrel. Being that it is the gateway from one side to the other, it is essential that the evaporator is dependable and consistent.
