Asda keeps the bugs at bay
May 1st 2008 Flying insects and
prevailing winds are being
kept at bay by Airbloc air
curtains at Asda's
distribution depot in
Chepstow.
Nine 4m high loading
bay doors, between 3.5
and 4m wide, are in use
24h and the 45 000m2
facility is expensive to heat
to the required constant of
15°. A solution was provided
by vertically positioned
Airbloc AB ambient air
curtains beside each door.
At critical velocity across
each doorway the air
curtain produces a sheet of
cold air, providing the
turbulence needed to
exclude winds (up to
11mph) and flying insects.
Mervyn Bull of Encon,
the company that installed
the curtains, says "The cold
air blasting across
doorways is highly effective
in preventing wasps and
flies getting in and
potentially contaminating
the food. More articles from Airbloc- Use Ambirad: |
