Watlow, a privately-owned company, is the industry leader in the design, manufacture and integration of complete thermal systems including electric heaters, temperature sensors, temperature controllers, power controllers and supporting software. At Watlow, we are constantly driven to do more to help our customers. We take on big technical challenges. We are committed to projects that help our fellow human beings and we strive to learn more. From single components to high performance systems, we bring our thermal expertise to numerous applications, including semiconductor processing, energy processes, diesel, foodservice equipment, life sciences and others.
Watlow was founded in 1922, and was built on the family’s passion to “be the best.” This dedication created a steady stream of new products, a devoted and capable workforce and steady growth.
Today, 90 years later, we continue to strive to “be the best” by following the principles of Lean, an organizational philosophy that promotes continuous improvement. We call it the Watlow Way. The Watlow Way takes us back to our roots because it is a people-centric strategy that drives us toward stronger technical capabilities and continuous improvement, with the ultimate goal of creating superior thermal solutions for our customers.
