Our air curtains conserve energy and improve comfort by limitingthe escape of internal heat, reducing cold drafts and providing awelcoming down flow curtain of warm air at entrance ways in industrialplants and store buildings. The resulting mixture of warmed air dispersesgently in all directions at floor level to give uniform temperature over awide area from floor to ceiling with only a few degrees difference. CONVENIENCEOur air curtains allow personnel and cargo to pass freely from onearea to another while maintaining desired temperatures.An added safety feature is the free flow of traffic with an unobstructedview through the opening, eliminating doorway accidents.TYPICAL USESEasily mounted over entrance ways of warehouse doors up to 16 feet high, the air curtains direct an invisiblestream of stratified heated air downward. In addition to adding to employee and customer comfort duringcold weather they provide important energy savings in three ways:1. In cold weather they reduce the load on heating systems. By drawing warm air down to floor level whereit is needed, our air curtains utilize the 50% of wasted heated air trapped under ceilings. Stratified air ismixed and circulated with building heat and heat given off by lights and machinery, etc.2. The high velocity curtain of air deflects winds and reduces excessive heat loss through open doorways.3. During warm weather they can direct a stream of air downward to help keep dust, dirt, insects and fumesfrom entering through open doorways. If air conditioning exists in the building during warm weather, the air curtains can be used to prevent loss of conditioned air as well.
