'Open Door' Trading
Managers of retail and commercial outlets know the importance of accessibility for their customers. They also know that adopting a policy of ‘open door’ trading means the issue of cold draughts and high energy bills will need addressing.

Energy savings
An air curtain does not act as a psysical 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 Technology
With any air curtain it is essential that the ‘jet’ of air reaches the floor and covers the entire door width. To ensure this and guarantee optimum energy-efficient performance all Biddle air curtains are subjected to rigorous research and development programmes, often in association with external organisations such as BSRIA, the Dutch research institute TNO and the Technical University of Delft. This work has established that without careful control of discharge velocity and temperature, and without use of Biddle’s patented rectifier, laminar and energy efficient flow is not achieved.
