Capillary thermostat, also known as liquid expansion thermostat, is made based on thermal expansion and contraction principle.
The WYG capillary thermostat,with adjustable operating temperature, is designed for temperature control. Its quick response can well prevent the unacceptable heat of water heaters, and guarantee people’s safty. WQB series capillary thermostat is often used as a thermal protector in electric water heaters. The WYG and WQB combination is a good TCO solution for water heaters.
Thermostat, WQB series, has the advantages of accurate temperature controling, great contact capacity, high safety. It is used as a protector of all-pole disconnection, which is suited for water heater, water boiler and so on.
Thermostat, WYG series, utilizes the ceramic switch box, has the advantages of accurate temperature controlling, wide control range, great contact capacity, high relibilities and thin thickness . It is suited for electric heater, electric boiler, cylinder washer, electric oven and so on, as electric- -thermal control. It is also suited for room temperature control and refrigeration control.
WQH Series thermostat is with optional lengths of temperature sensor. It works under resistive load. It is in wide use in electric heater in North American. UL certification for our products is available.
