Capillary thermostats
Capillary thermostats from Hangzhou Well Thermostat Co., Ltd. are liquid expansion devices engineered for precise temperature control in heating applications. They operate on the principle of thermal expansion, where a liquid inside a sealed capillary tube expands or contracts with temperature changes, actuating a switch to maintain a set point. These units are supplied as OEM components for integration into electric water heaters, boilers, ovens and warm air heaters, with adjustable temperature ranges tailored to the appliance’s requirements.
The thermostats use a durable metal housing and capillary assembly to withstand high pressures and temperatures typical in HVAC and domestic heating systems. Typical industry builds incorporate a brass or stainless steel capillary tube, with a length standard between 1.5 m and 3 m to match common appliance layouts. The sensing bulb is usually copper or stainless steel, selected for its thermal conductivity and corrosion resistance in wet or acidic environments.
Industrial buyers source these thermostats for residential and commercial heating equipment where reliability and long service life are critical. Common trade terms for such components include FOB Ningbo or Shanghai, with packaging in carton boxes of 50 to 100 units to prevent damage during transit. Buyers should confirm the temperature range, capillary length and switch type to ensure compatibility with their specific heating system design.

Sourcing Capillary thermostats from Hangzhou Well Thermostat Co. - China Import Guide
Before ordering, verify the thermostat’s temperature range and set point accuracy to ensure it matches your appliance’s operational requirements. Request the supplier’s calibration data or third-party test reports to confirm the thermostat’s performance under load.
Confirm logistics details such as lead time, Incoterms (FOB Ningbo or Shanghai are common for this origin) and payment terms. Capillary thermostats are typically shipped as non-hazardous goods, but buyers should check for any restrictions or special handling needs for their destination.
Inspect the capillary tube and sensing bulb for damage upon arrival, as kinks or dents can affect accuracy. Test the switch’s continuity and the thermostat’s response to temperature changes before integration into the final product. Request a certificate of conformity to ensure the units meet industry standards for safety and performance.
