High efficiency air curtain
With open doors the difference between the indoor and outdoor temperatures
leads to an exchange of air, with precious heat being lost to the outside and colder
outside air flowing in. Installing a DoorFlow air curtain above the open entrance
prevents heat loss to the outside and heats up the cold outdoor air to the desired,
comfortable room temperature.
All Biddle air curtains come with the patented rectifier technology. This technology
ensures that the turbulent air flow from the fans is converted into a laminar air
stream. This makes it possible to reach the floor with much less air whilst the door
opening is properly protected. The comfort and efficiency are much higher compared
with conventional air curtains.
User-friendly
The DoorFlow air curtain comes as a standard with a user-friendly control panel. The
manual setting of the standard controller makes it possible to choose the right fan
speed of the air curtain: low - medium - high. If the DoorFlow is extended with a
room temperature control, the indoor temperature can be controlled manually as
well as automatically by means of the control panel (see page 6).
Fast and easy installation
The DoorFlow air curtain is mounted by means of threaded rods and is as a standard
ready to plug in. This makes the unit easy to install. Low voltage cables connect the
control panel “plug and play” to the unit. It is also possible to interlink different units
in a “plug and play” way.
