variety of different constructionmateri- als to suit all operating environments including all-stainless coils designed and manufactured to SANS 347 and ASME B31-5 specifications and welded according to ISO 3834 Part 2 quality re- quirements,” Banza tells African Fusion . From an original 2 500 m 2 facility, HCHE has rapidly expanded and is al- ready looking to expand on its 16 000m 2 production facility inElandsfontein, east of Johannesburg. “We moved into these premises at the start of 2015with almost 300 people. We are nownearing 350 and are looking for additional space next door. We have added a newHVACdivision toour facility in order to handle specialised products such as rooftop air-handling units and we have recently launched a product called the Dew Maker, which extracts drinking water from the air. We design all of our products with sustainability in mind,” Banza says. Quality Requirements. African Fusion talks to Hans Banza, the company’s responsible welding coordinator.

We offer a

One of the biggest stainless steel products HCHE has manufactured thus far, an 890 kW spiral freezer manufactured by the compa to freeze poultry products.

Success at the Stainless Awards HC Heat Exchangers was a joint run- ner up in two categories of the Sassda Columbus Stainless Awards in 2016: the Food and Beverage category and the Engineering category. The Food and Beverage accolade was awarded for oneof thebiggest stain- less steel products HCHE has manufac- tured thus far, an 890 kW spiral freezer manufactured by the company to freeze poultry products. The unit, constructed almost entirely from 304 stainless steel, with only the fins and fan panels being made from aluminium, is designed to freeze over 10 t of poultry per hour. Cold air leaves the heat exchanger at -34° C and is blown into a 10mhigh cylindrical room, which contains the conveyer car- rying the poultry. As the product passes through the system it is quickly frozen and packaged. One of the key challenges faced in
