A Comfort Air Curtain from Biddle will provide an energy-efficient solution for your commercial requirements. An air curtain does not act as a physical barrier, but conditions incoming air and reduces the amount of warm air escaping from the building. An air curtain should therefore enhance comfort and save energy.
Patented technologies
With any air curtain it is essential that the ‘jet’ of air reaches the floor and covers the entire door width. Research and development programmes have established that without careful measurement of temperatures within the door opening, and without automatic control of discharge velocity and temperature, laminar and energy efficient flow cannot be achieved. Use of Biddle’s patented rectifier technology ensures a laminar air stream and a climate separation efficiency of over 90%.
