The global impact of COVID-19 on our people and the global economy is significant, and Watlow has taken a comprehensive approach to deal with the current crisis. Our contingency planning includes protecting our team members, communicating often with our customers and partners and maintaining the continuity of supply lines.

At the beginning of the pandemic, we set two priorities that guide our responses and decisions: the health and safety of our team members while continuing to supply essential products needed by our customers.

If you have questions about how the pandemic is impacting Watlow or Watlow’s response, please contact your Watlow representative.

Custom Abrasion Resistance Meets the Needs of Aluminum Manufacturer


A manufacturer of aluminum products performs heat treating in a gas fired, high velocity air circulation furnace at temperatures of 900 to 1000°F (480 to 540°C). The high-velocity air circulation was causing the thermocouple to rub against furnace components resulting in insulation failure.


To solve this abrasion problem, Watlow developed a special wire construction featuring a tighter, higher pick count weave.

Additionally, an improved impregnation was developed to withstand the high temperatures. The new impregnation doesn't become stiff and brittle, preventing the insulation's glass fibers from fracturing in the high velocity air.
