WKF series high power electric thermostat

The high power electric thermostat is suitable for incubators, laboratory ovens, water baths, sterilizers, dishwashers, steam tables, scalding tanks and other equipment where a close temperature differential is required.

Adjustable capillary thermostat WKF series is intended to maintain the required temperature in a device or its parts. A rise in temperature causes the expansion of liquid within the bulb and capillary. The liquid acts on a diaphragm within the plastic housing to open electrical contacts.
Temperature range 35°C…+85°C, 30°C…+110°C,50°C…+200°C,50°C…+320°C, other temperature range can be customized on request.
Electric rating 32A/250VAC.
Capillary and bulb material – stainless steel. Capillary length 1000mm.
