Ambient air curtain RONDELL EC series

panel-mountfor revolving doors

Revolving doors and air curtains seem to be contradictory, but in praktice this proofs to be an excellent combination. The use of a revolving door inside a building prevents draught. With no direct connection between inside and outside air, optimal inside climatic conditions are achieved.When the door revolves, cold air is entrained with the door wing and the difference in temperature between outside and inside air results in a cold zone directly behind the door.For heating the air curtain is to be installed directly behind or inside the revolving door which leads to pleasurable climatic conditions in the entrance area.The air curtain blows warm air downwards to the front of the opening of the revolving door.This warm air stream is heating the inside air down to the bottom and shields it from cold outside air. The duct with the aluminium outlet grille matches the door radius.
