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.

Application: Propane Dehydrogenation

Related Industry: Petrochemical Refining

Hydrocarbon feed is mixed with hydrogen-rich recycle gas and is fed into an electric heater to be heated to over 540°C (1000°F) before entering the reactors to be converted at high mono-olefin selectivity. Several inter-stage heaters are used to maintain the reaction by supplying continuous heat to counter the endothermic reaction.
