Snap Disc Fan and Limit Thermostat SwitchAt Senasys, we recently took on an exciting challenge when a manufacturer approached us with a specific temperature monitoring application. They were looking for an alternative to the Honeywell Fan and Limit Thermostat Switch, specifically the P/N L4064B2236, which they had been using in a heated duct system. Our mission was clear – design a solution that not only switched control for the fan but also set precise temperature limits within the duct system. While the Honeywell Fan and Limit Thermostat Switch had its merits, we saw an opportunity to provide a more tailored and efficient solution using our expertise in temperature control technology.

Leveraging the capabilities of our TC Series thermostats, which, like the Honeywell counterpart, break on temperature rise, we set out to create a solution that would not only meet but exceed the manufacturer’s requirements.

In a departure from the conventional single thermostat switch approach, we implemented a unique solution using two snap disc thermostat switches. The first snap disc was strategically used to control the fan, while the second snap disc, positioned ahead of the first, acted as a high limit. This innovative configuration allowed us to precisely manage the temperature range within the heated duct system.

This collaboration exemplifies Senasys’ dedication to delivering cutting-edge solutions that are not only effective but also tailored to the specific needs of our clients. By harnessing the capabilities of our TC Series and adopting a dual snap disc approach, we showcased our commitment to innovation in the field of temperature control.

The success of this project reinforces us as a reliable and forward-thinking partner for manufacturers seeking advanced and customized temperature control solutions. We take pride in being at the forefront of technological advancements, continuously pushing boundaries to meet the diverse and evolving demands of our esteemed clientele. At Senasys, innovation is not just a goal – it’s our commitment to shaping the future of temperature control solutions.

Digital Temperature Switch Controls Fan and Limit

This application is also a great fit for Senasys’ new digital switch to control both fan and limit. The electronic temperature controller is a cost-effective, temperature switching solution that allows tight differentials and tolerances that mechanical thermostat switches can’t provide. Although, the best solution would be to mount the PC board into our TC series housing to sense the bi-metal coil movement. This versatile switching solution can be customized in a variety of ways making it a great solution for your next application! For more information, visit the product page.
