Industrial air curtain,

Free Industrial ACces
Industrial building doors are often open for long periods of time to facilitate
transport in and out of the building. However, open doors result in a loss of heat to
the outside and the ingress of cold air. This disturbs the climate within the building,
which leads to uncomfortable working conditions for staff. Internal transport does
not want to be hindered by closed doors either, so internal doors between production
halls and storage spaces for instance, are open all day long. If there is a difference
in temperatures between these rooms, air will exchange, leading to draughts.
The new Biddle industrial air curtain, model IndAC, is highly suitable to handle these
kinds of situations. Many years of experience in combination with scientific
research, forms the basis for the IndAC, which has a distinct robust appearance.
The IndAC makes the entrance accessible for transport and prevents cold air entering
the building, which results in free access, comfortable working conditions and less
absence due to illness.
Energy saving solution
Doorways of industrial buildings are usually faced with direct wind attack, or suffer
from under-pressure, resulting in large air volumes being introduced into the working
area. In order to provide optimum screening, a unit with large air volumes is required
in most situations.
Therefore, Biddle has optimised the discharge pattern for industrial applications.
The air passes through the curved discharge section with minimal resistance. The
patented Double Rectifier ensures that turbulent air from the fans is bundled into a
laminar air stream, discharging in a straight vertical line to the floor. Additionally, the
homogeneous discharge pattern across the door provides optimum heating of cold
outside air, eliminating draughts in the building and preventing expensive energy
being lost to the outside.
The curved design of the discharge section also means that it is easily installed
close to the door, preventing air leakages. The result is a well screened doorway
with a minimum loss of heat.
