WKF series high power electric thermostat

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.
