Duct Fan and Limit Thermostat Switches
Original equipment manufacturers worldwide use thermostat switches designed and manufactured by Senasys Inc. No matter which style or model you choose, all of the Firestat Duct Fan and Limit Thermostat Switches operate using the same physics. A helix bi-metal element senses a rapid temperature change. When the temperature changes the bi-metal expands and triggers a snap action switch and either opens or closes a circuit.
HVAC and Building Automation System manufacturer’s incorporate Senasys’ high quality, UL approved firestat thermostat switches and control.
Firestat 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 do not need. Please contact our direct sales support to receive information on any of our switches.
Made in the USA
Senasys takes pride in quality control and reliable operation of our components. Every switch is individually 100% tested before it leaves the plant.
