PROJECT
INCORPORATING COLD CHAIN
The cooling coils are equally split between
the two racks and each have a plate heat
exchanger to provide a portion of the
chilled water load.
During the day, when the pack line is
in full production, 50% of the compressor
capacity is dedicated to the pre-coolers
and air temperature in the pack line area.
At night, the total compressor capacity is
dedicated to the rapid cooling tunnels and
holding room.
Variable speed drives fitted to each
compressor facilitate the stable and
efficient distribution of cooling capacity
to different areas at different times of the
day and night. The two large air handling
units distribute air down the full length of
the packing area through two 900mm-
diameter fabric ducts.
“Energy saving, safety, temperature
control, productivity, and quality of finish,

were prime considerations in the design
and construction of Luiperdshoek, and is
evident when viewing the facility,” says
Kevin Schlemmer of CoolCheck.
To enhance the outer appearance
of the pack house, the two evaporative
condensers have been enclosed in a room
with louvres, seen to be part of the overall
building perimeter. The fans, normally
