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.

Tubular Plug Heaters are Cleaning Up


Replacing a Chromalox® flange heater.


The customer is a pump manufacturer who cleans parts with 190°F water. The parts are assembly parts for the pumps. They were using a 5" 150-lb flange from Chromalox®.


We replaced the Chromalox® heater with a 2 ½ in. stainless steel screw plug, Incoloy sheath, 480V, 38 kW, 90 W/in². We replaced it with a shorter B dimension (33 in.) quicker delivery and a smaller mounting fitting. The customer made an adapter to fit the 2 ½ in. screw plug in place of the 5 in. flange.
