The most economical of Schwank luminous heater

Conventional heaters only heat the surrounding air with the warmest air being trapped near the ceiling. ecoSchwank overhead heaters provide infrared heat waves that radiate down to ground level where the heat can be absorbed by people and objects.

The IR high intensity eco line of Schwank heaters is ideal for indoor industrial and commercial l facilities with high ceilings up to 70 feet that have large energy requirements and tight budget projects. They provide great long-time value with a low upfront investment and low operating costs. Plus, you’ll be doing your part to reduce CO2 emissions.
