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, 1 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 3 1.

Plastic sheeting covers the pallet stacks in the cooling tunnels to force the cooling air through the cartons. 4. The loading bays are fitted with insulated docking seals and equipped with docking levellers and guide curbs for easy docking of vehicles. 4 2 14 www.coldlinkafrica.co.za COLD LINK AFRICA • March | April 2018
