Patented Double Rectifier
To minimise turbulence in the discharge airstream, and ensure the air reaches the floor, Biddle have invested heavily in the development of the patented rectifier. This rectifier comprises an optimised number of blades, with a precise relationship between their length and spacing, to create a laminar airstream which reduces turbulence and energy consumption and increases throw for a given air volume.
Whether using water or electric heating, an advanced energy saving controller - the ECONTROL – when combined with the Invisidor STYLE air curtain optimises energy savings.
Operated either manually or automatically the ECONTROL will not just control air curtain performance but will also control comfort conditions in the entrance environment through energy saving adjustment of air volume and temperature. Timer clocks, door contact switches or room thermostats can still be linked to the air curtain for added flexibility.
