Comfort Air Curtains

Looking for an energy-efficient solution to meet your commercial requirements? Look no further than Comfort Air Curtains by Biddle. Designed to enhance comfort and save energy, these innovative air curtains condition incoming air while effectively reducing the escape of warm air from your building. Discover the perfect solution to optimize your indoor environment with Comfort Air Curtains from Biddle.

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%.
