The calorSchwank tube heater is the premium model amongst Schwank tube heaters. Thanks to its intelligent burner technology, high-quality reflector insulation as well as highly reflective reflectors, it belongs to the most efficient heaters of its class. In contrast to the basic model infraSchwank, this tube heater consumes approximately 20% less energy. In spite of its low material strength, the insulation used achieves the fourfold effect as compared to conventional insulation materials. These energy efficient heaters ensure a high ErP value and guarantee economical operation.
