Additional applications
Air curtains and revolving doors:
the perfect combination
A revolving door in the entrance is an architectural step towards creating a comfor-
table climate in a shop or a public building. But every time a customer goes through
a revolving door, cold air comes inside. Customers and staff find the draught very
unpleasant. Besides, heating the cold external air costs additional energy.
For this reason Biddle has developed a solution specifically for revolving doors, named
model tourniquet. The striking feature of this model is that it is supplied with a curved
outlet grille, precisely in line with the curve of the revolving door. This protects the
entire door opening. The smooth discharge grille fits nicely into the whole and the air
curtain is invisibly hidden away in the ceiling or upper part of the revolving door. The
result is a perfect, energy-efficient climate separation.
Easy maintenance (no filters)
Air curtains in combination with revolving doors are hard to access, because they
are built into the ceiling. Therefore filters are often not replaced or cleaned. The great
advantage of the tourniquet DoorFlow air curtain is that it does not contain any filters.
This means that maintaining and cleaning filters is a thing of the past.
Custom work
Biddle tourniquet air curtains are suitable for all types of revolving doors. The curve of
doors (radius) and type vary per project, so the discharge grille is custom made. For
further details please contact the sales department at Biddle.
