Non-Indicating Heater Controls

This is a collection of analog controls designed for over-the-side immersion heaters. They are built to work with heaters that have a built-in over-temperature sensor (thermal protector); when ordering, please specify the type of thermal protector your heater has.

If you have questions about which control goes best with your heater or application, please call our engineers at (866) 685-4443, send us an e-mail, or fill out one of our contact forms
