        • An EC Motor is 2x more efficient than a PSC motor (Permanent Split Capacitor) and 3x more efficient than a Shaded Pole AC motor which is commonly used for infrared tube heaters.
        • A constant torque EC Motor leads to more robust and stable combustion through the heaters’ entire range of operation and external pressure changes.
        • Schwank has engineered a customized control board (power input 24VDC) built specifically for the 2-stage phantomSchwank Series.

        Intelligent control technology for heating systems

        • Optimized reflector geometry provides increased efficiency over conventional reflectors and maximizes heat distribution throughout the entire radiant area.
        • Providing a more uniform heat distribution across the same heating surface.
