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.

Silicone Rubber Heater Puts Brakes On Truck Air Brake Moisture Problems

Problem:

Air brakes on trucks need protection in winter against moisture freezing that can cause brake failure.

Solution:

Air dryers with a Watlow silicone rubber heater that prevents venting valve freeze-up in temperatures as low as -70°F (-55°C).

Watlow engineering worked with this manufacturer to improve his product quality and keep costs at a minimum. The customer sends a casting to the Watlow plant where the heater is vulcanized to the casting in a specially adapted hydraulic press. This is the most efficient method of heat transfer because there is a minimum amount of insulation (mastic or glue) between the heater and the part. Some heaters are 12 volts, others 24 volts, so Watlow color-codes the leads to decrease the likelihood of an improper installation.
