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 Adds Moisture To Oxygen For Patient Comfort

Problem:

Moist oxygen is critical for patients requiring respiratory therapy. Humidity helps the lung absorb life-giving oxygen and greatly aids patient comfort. A problem arises with oxygen storage. It must be dry to prevent corroding the high-pressure tanks, and to prevent condensation from forming and freezing during use. To get around this "dry oxygen" problem, a medical equipment manufacturer was developed a fail-safe way to put moisture back into the oxygen by employing an electrically heated humidifier.

Solution:

Watlow engineered a flexible heater with holes to accommodate a thermostat, high-limit control and support framework. Vulcanizing the heater to the humidifier's base was recommended to improve performance by eliminating a layer of mastic that would otherwise act as a thermal barrier. This complete sub-assembly, with UL® and CSA approvals, saved the manufacturer the added cost and labor associated with producing the part in-house.
