Senasys Capillary Thermostats offer highly reliable temperature switching and are 100% tested and sold across the globe to original equipmentCapillary Switches are Temperature Compensated manufacturers.

Before leaving our facility, these switches undergo submersion testing to verify the temperature which the switch operates. Our quality assurance team submerses 100% of the bulb and three inches of the capillary tube into a cooling / heating circulation bath on temperature rise. The depth that the bulb is immersed in any medium will greatly effect the temperature the capillary thermostat operates. Depending on the dimension and filler used, it can change the characteristics as much as 3°F per 1/4″.

Each of our capillary diaphragms consist of a bulb, capillary tube and a diaphragm. The diaphragm is engineered for a specific movement at a given temperature change. The assembly is the same diaphragm assembly used in our other capillary thermostat controls. It is available separately for use in OEM equipment.

Original equipment manufacturers worldwide use thermostat switches designed and manufactured by Senasys Inc. 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.

Commercial food equipment manufacturer’s incorporate Senasys’ high quality, UL approved thermostats and controls. Other important applications are pool and spa, HVAC equipment and products for the home.

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.

Ambient Compensation

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.

Custom Options

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.
