increases machine wear and tear.
The rational fire design on the facility
called for fire prevention in the high-rise
building as opposed to a traditional
sprinkler system. WSP, together with
Karan Beef, went to Europe to inspect an
installation done by Wagner, a German
company specialising in hypoxic systems.
Wagner uses technology whereby
nitrogen and oxygen are separated
by compressing ambient air through
active carbon. The oxygen is absorbed
in the active carbon and the nitrogen
introduced into the protected area

to reduce the oxygen concentration.
The lower concentration of oxygen
prevents a fire from starting. Both parties
were impressed with the quality and
performance of the solution, and after
extensive negotiations, Wagner was
the chosen supplier for this system. The
hypoxic system installed at Karan Beef is
also the first of its kind in South Africa.
As part of the rational fire design, fire-
rated insulated panelling was specified
for the entire facility. Going through a
vigorous adjudication exercise, Kingspan
was selected as the sole supplier of
the panelling. Further to this, their new
QuadCore panel was selected for use.
WSP, together with Karan Beef, went
through a detailed exercise on which
method of carton freezing to make
use of. Critical issues such as product
movement, power efficiency, floor
space, and manning requirements were
considered and the best possible solution
