Local context
Working in Benrose
We service Benrose Industrial and the surrounding blocks of Benrose, Johannesburg, with access off the M2 and N17. 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.
