Door Heater Air-Curtain

Berner International Corp. offers the VTH, a Venturi-style door heater air-curtain. The electric heater combines a hemispherical heating element array with a new mounting strategy at the blower inlet. The patented design uses the Venturi effect to draw air through the heating element via the blower inlet before it enters the discharge airstream. The discharge airstream velocity remains unobstructed in a near 100% efficient heat transfer, full laminar pattern for an optimum aerodynamic performance that creates an environment-separating air seal across any open doorway while providing auxiliary heat as needed.
