Local context
Working in Rustivia
We service Rustivia Industrial and the surrounding blocks of Rustivia, Germiston, with access off the N3 and R24. 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.
