These mechanical temperature controls are designed for indoor heating, cooling, and refrigeration applications. They are compatible with single-stage systems, those with a single output level that allow the system to be either on or off. Equipped with a 96 inch capillary tube and sensor, you can monitor and regulate the temperature of the ambient air, a liquid, or a gas a short distance away from the controls. Thermostat enclosures meet NEMA 1 for use indoors and can be used with optional, closed tank fittings and immersion wells for immersion applications. High electrical ratings allow operation of most equipment without use of relays or motor starters.
Hydraulic action element.
Dustproof steel case with top and bottom knockouts.
Temperature dial graduated in °F and °C and can be adjusted through cover.
Model 1609-90
