Local context
Working in Cornubia
We service Cornubia Industrial and Business Estate and the surrounding blocks of Cornubia, Durban, with access off the N2 and M41. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.
