The refrigeration engine behind South Africa’s cold chain
WHILE shoppers see refrigerated display cabinets in stores, the real refrigeration work takes place behind the scenes; in plant rooms and on rooftops, where compressor racks, heat exchangers, and condensers provide the cooling essential to modern food retail. This is Colcoil’s area of expertise.
Established in 2013 as a division of Colcab, Colcoil Technologies manufactures the specialised refrigeration equipment that contractors install in commercial and industrial settings. “Colcoil produces heat exchangers and compressor racks; the engines that drive refrigeration,” explains Fanie Viljoen, Divisional Director. “This equipment is typically unseen by the public, but it is vital for preserving fresh produce, perishables, and frozen foods.”
Operating from its Blackheath facility next to Colcab’s main factory, Colcoil serves a unique market. “Our customers include refrigeration contractors, OEMs, and consulting engineers,” Viljoen says. “We offer both bespoke solutions and a comprehensive range of standard products, primarily serving contractors and installers.”
This contractor-focused approach enables Colcoil to serve diverse sectors beyond retail. The company supplies custom units for agriculture, marine and fishing vessels, blast freezers, underground mining cooling, and HVAC applications. “Our extensive experience allows us to provide solutions for distribution warehouses, data centres, food processing plants, hospitals, fruit pack houses, and laboratories,” says Viljoen.
With an estimated 35% market share, Colcoil continues to grow faster than its more established parent company. The division expanded its product line five years ago, adding compressor racks and packs to its original heat exchanger offerings.
Recent years have seen significant investment in technology. “We’ve acquired CNC automated machines, including 3D tube benders and manifold extractors,” notes Viljoen. “This automation enhances efficiency, productivity, and product quality.”
Colcoil is also committed to sustainability, offering CO2 and R290a refrigeration systems for environmentally conscious clients. “We supply CO2-compatible equipment, compressor racks, evaporators, and gas coolers that use natural refrigerants with zero global warming potential,” Viljoen says. “This not only supports retailers’ environmental goals but also future-proofs their refrigeration plants.” The company also meets the growing demand for data centre cooling, driven by the rise of AI in South Africa.
Continuous engagement with international markets ensures Colcoil remains at the forefront of technological advancements. “We attend trade fairs in Europe and China to stay updated,” Viljoen adds. “Our expertise, combined with local manufacturing agility, positions Colcoil for ongoing growth in South Africa’s refrigeration sector.”
