Local context
Working in Modderfontein
We service Modderfontein Industrial and the surrounding blocks of Modderfontein, Johannesburg, with access off the N3 and R25. 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.

FAQ
Güntner air-cooled condenser cleaning in Modderfontein
How fast can a technician service Güntner equipment at a mining & bulk air cooling site in Modderfontein?
Modderfontein sits on the N3 and R25, so our Johannesburg dispatch reaches most Modderfontein Industrial sites inside a standard callout window. Emergency air-cooled condenser cleaning runs 24/7 because underground heat stress limits shift productivity.
Do you stock OEM components for Güntner systems?
Yes — Güntner EC fan modules, defrost heaters and coil blocks. Güntner (Germany) equipment on R717/R744/R134a charges is supported with the fast-moving spares held at our Pretoria North workshop and non-stock items brought in on OEM order.
What pressure testing and gas compliance certificates are provided?
Every air-cooled condenser cleaning job closes with a pressure test record and gas handling Certificate of Conformance issued under SANS 10147 by a SAQCC Gas registered technician, plus the MHSA documentation your auditors expect.
What operating envelope do you commission this equipment to?
Mining & Bulk Air Cooling run at +2 °C to +12 °C chilled water at 90–100% RH, with air-cooled condenser cleaning performed against +40 °C to +55 °C condensing in peak ambient. Underground heat stress limits shift productivity
