Evaporation as a method of concentration can produce solids contents that range from 0% to as much as 92% with scraped surface evaporators (used in select applications).

Evaporator - Wikipedia

Uses. One kind of evaporator is a kind of radiator coil used in a closed compressor driven circulation of a liquid coolant. That is called an air-conditioning system (A/C) or refrigeration system to allow a compressed cooling chemical, such as R-22 (Freon) or R-410A, to evaporate/vaporize from liquid to gas within the system while absorbing heat from the enclosed cooled area, for example a .
