Comprehensive Testing for Quality Assurance
Before leaving our facility, each thermostat undergoes thorough submersion testing. Our quality assurance team immerses 100% of the bulb and three inches of the capillary tube into a cooling/heating circulation bath to verify the temperature at which the switch operates. The immersion depth of the bulb in any medium significantly impacts the thermostat’s operational temperature. Depending on the dimensions and filler used, characteristics can vary by as much as 3°F per 1/4 inch.
Submersion Testing Process
- Immersion Depth: 100% of the bulb and three inches of the capillary tube
- Testing Medium: Cooling/heating circulation bath
- Impact on Characteristics: Up to 3°F variation per 1/4 inch
Precision Engineering of Capillary Diaphragms
Each capillary diaphragm consists of a bulb, capillary tube, and a diaphragm, engineered for specific movements at given temperature changes. This diaphragm assembly, used in all our capillary thermostat controls, is also available separately for OEM applications.
Components of Capillary Diaphragms
- Bulb: Encapsulates the fluid
- Capillary Tube: Connects the bulb to the diaphragm
- Diaphragm: Moves in response to temperature changes
Applications in Various Industries
We design and manufacture thermostat switches for OEMs worldwide. Regardless of the style or model, all our capillary thermostat switches operate on the same basic principle. A fluid encapsulated in metal expands or contracts with temperature changes, moving a diaphragm that interacts with a snap-action switch to open or close a circuit.
Key Industries and Applications
- Commercial Food Equipment: High-quality, UL-approved thermostats and controls
- Pool and Spa Equipment: Reliable temperature control solutions
- HVAC Systems: Precise and durable thermostats
- Home Products: Consistent and dependable temperature regulation
Capillary thermostats are trusted by OEMs around the globe for their reliability and precision. Our rigorous testing processes and engineering excellence ensure that our products perform optimally in various applications.
