The Firestat Duct Fan and Limit Thermostat Switches operate on the principle of helix bi-metal elements, ensuring HVAC safety. These elements detect rapid temperature changes, expanding accordingly to trigger a snap action switch that either opens or closes a circuit. Typically installed in air ducts, these switches are vital for shutting down heating, air conditioning, and ventilation systems in apartment complexes and other multi-dwelling units when air temperature surpasses the designated threshold.
When it comes to ensuring the optimal performance and safety of your HVAC system, Firestat stands out as the premier choice for duct high limit switches made in the USA. With a comprehensive range of features, including adjustable or fixed options, a wide operating temperature range, and customizable probe lengths, our switches are designed to meet the diverse needs of your duct system with unmatched precision and reliability.
