LS Series
Water Media LS Series Temperature Control
Temperature control units circulate a fluid medium (typically water or oil) through a process application for HEATING can supply temperatures between 30° to 400°F (depending on medium). Temperature controller units service only a single process at a time, but are designed to be moved between process applications as the need requires.
A pump circulates water through the process. An electric heater and a cooling valve work together to control the water temperature. Theses units are portable and require a plant water supply source and are available with a variety of different control instruments, heater sizes, and cooling valves.
