Da Gama’s Zwelitsha textile mill was constructed in 1946, and its steam system is dated. The company employs a diverse mix of manufacturing technologies including weaving, washing, bleaching, dyeing, printing, heat treatments and others, many of which require steam for their operation. While most of the investments made by Da Gama since the original assessment have been in the area of production capacity, these newer technologies have nevertheless had some flow-through benefits for steam system efficiency.
