Fixed Duct Limit ControlsSenasys is the manufacturer behind the Firestat adjustable duct limit switches, engineered to swiftly detect sudden temperature spikes within HVAC duct systems, often indicative of fire hazards. Equipped with a helix bi-metal element, these switches promptly trigger a single pole, single throw (SPST) switch as temperatures rise, providing vital safety measures. Operators have the flexibility to fine-tune the adjustable switch to detect temperatures spanning from 100°F to 250°F, ensuring precise monitoring in various environments. Additionally, the switch’s robust enclosure is designed to withstand ambient temperatures ranging from -40°F to 190°F, while the bi-metal element itself can endure temperatures of up to 350°F, ensuring durability and reliability in demanding conditions.

CEMCO Duct Limit Switches

The Firestat Duct Fan and Limit Thermostat Switches operate using the same physics to ensure HVAC safety. 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. These switches are commonly installed in air ducts designed to shut down heating, air conditioning and ventilation equipment in apartment complexes and other multiple dwelling units when air temperature exceeds the set point.
