We excel at helping OEMs solve problems.

Tempro, a division of Senasys, is a leading manufacturer of Industrial Thermostats and Guards that are commonly found in commercial, industrial and agricultural settings. Senasys acquired the Tempro product line in 2019. Tempro products are manufactured overseas in China, while Senasys owns the tooling and design that are used to produce them.

Tempro stocks these finished products in their facility in Eau Claire, WI, which provides the ability to reduce lead time and ensure quality for our customers.

Since acquiring the Tempro product line, Senasys has made vast improvements on product quality and reliability, as well as lead times, while still maintaining a competitive cost for our customers.

In addition to industrial thermostats, Senasys produces over a million products annually across a diverse range of more than 15 varieties. We proudly serve an array of industries, including food service, medical, industrial, HVAC, aerospace, railway, aquatic, electronics, and more. Our dedication to innovation and quality has established us as a trusted partner in these diverse fields.

Senasys excels at helping OEMs using small to large volumes of devices solve problems related to temperature, pressure/vacuum, air flow, industrial machining and more. We strive to be a fast and dependable supplier for all our customers. This includes everyone from small manufacturers all the way up to Fortune 500 companies, and everything in between.

With our in-house fabrication shop, we have the ability to customize our products to meet requirements, whether it’s a specific bracket specification to meet fit requirements, terminal connections and more.
