Brief description
Tandem door air curtains are used to screen open doors from the ingress of cold air. Room air is drawn in by a radial fan
through the inlet grille (with optional filter) and passed through the heat exchanger or partially passed through the heat ex-
changer (Tandem technology). The air stream is directed downwards in a low-turbulence manner by the adjustable rectifier.
