Capillary thermostats and thermowells are commonly used in various HVAC (Heating, Ventilation, and Air Conditioning) applications due to their simplicity and cost-effectiveness. These thermostats consist of a sensing bulb connected to the main unit via a capillary tube, which allows them to sense temperature at a remote location and control the HVAC system accordingly.

Bulb & Capillary Thermostats
Original equipment manufacturers worldwide use thermostat switches designed and manufactured by STEMCO, a Division of Senasys. No matter which style or model you choose, all of the capillary thermostat switches operate using the same physics. A fluid is encapsulated in a metal and when the temperature changes the fluid either expands or contracts. This fluid change moves a diaphragm which is in touch with a snap action switch and either opens or closes a circuit.
Our capillary thermostats can be ambient compensated to offset the differential in temperature which keeps our thermostat controls more accurate as it’s environment changes.
Capillary thermostat switches built by Senasys can also be built to customer specifications. This insures you get the exact control you want without paying for features you don’t need.
