Temperature Limit Switch for Attic Fans

Temperature Limit Switch for Attic Fans

One of our customers down south (I mean we are in Wisconsin so really anything to us is down south) had a shed/workshop that he wanted to cool down without using an air conditioning unit. He wanted to put an exhaust fan on a thermostat so even if he was not in the building the fan would go on keeping his enclosed shed from overheating. A fire fighter friend of his let him know if you have a fire in that building that it is just going to feed the flames and the building will go up into smokes pretty quickly. After consideration, they decided to use a temperature limit switch to manage the shed’s attic fans.

They decided to place a high limit TC switch in the attic of the building to sense a high temperature over 200°F. This fan will cool the building if it goes above 80°F and if there is excessive heat sensed assuming a fire or smoke it would shut the blower off. Here we have a simple device with a simple real-life application. Do you have any cool applications that you are using for your products? If that answer is yes, please send an email to info@senasys.com with your application details!

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.
