A Note From Our Owners

April 12, 2020

Dear previous Customers and Vendors of Radiant Energy Systems, Inc, and Anderson Thermal Devices, Inc.

On Friday, March 13, 2020, a decision was made by the family ownership group to shutter both Radiant Energy Systems, Inc., and its sister company Anderson Thermal Devices, Inc., effective immediately, with all employees being terminated on that date.

The former senior managers of Radiant Energy Systems, including the General Manager/Controller, Chief Design Engineer, Controls Engineer and Vice President of Sales, (as well as other key production personnel) made a decision to continue the legacy of our founder. We have created a new entity named Infrared-Air Thermal Systems, LLC to service all previous and new customers from this point forward.

This period of uncertainty surrounding the Covid-19 virus has not been the best timing for this announcement and we ask for your patience and support as we work toward ramping up our manufacturing and service.

If you have any questions you may reach us at (833) OVENDRY (683-6379) or contact us via email at the following:

System sales –
Sales (parts), finance & admin – Engineering –
Controls –
Infrared lamps –

We also realize that there are many Radiant Energy Systems and Anderson Thermal Device customers who either had work in progress, or active Quotes before the closure so please don’t hesitate to contact us and we will do everything possible to assist in answering your questions and offering options.

Thanks again.
