Local context
Working in City Deep
We service City Deep Fresh Produce Market, City Deep Container Terminal and the surrounding blocks of City Deep, Johannesburg, with access off the M2 and N17 and N3. Highveld summers push afternoon ambients past 32 °C with heavy thunderstorm humidity, so condensers here are sized with a generous approach and cleaned before every summer.
