ultraSchwank highlights

The most efficient gas-infrared Schwank tube heaters

The ultraSchwank is clean burning and very efficient. Up to 68% of the gas utilized to power our ultraSchwank infrared tube heaters is converted into radiant energy that heats right down to the floor level. This model has a North American high radiant efficiency rating that is second to none.

Schwank engineers perfected this model using computer modeling of the burner as well as insulating the heater reflector system to increase the amount of heat directed to the floor. This equates to 50% energy savings for you.

This model has received two prestigious awards: 2010 Plant Engineering Product of the Year Award and Dealer Design Award.
