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 evaporator coil descaling in Modderfontein
How fast can a technician service Güntner equipment at a dairy processing plants 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 evaporator coil descaling runs 24/7 because chilled-water temperature rise stalls the pasteurising line.
Do you stock OEM components for Güntner systems?
Yes — Güntner EC fan modules, defrost heaters and coil blocks. Güntner (Germany) equipment on R404A/R717/R744 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 evaporator coil descaling 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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Dairy Processing Plants run at +2 °C to +4 °C at 80–85% RH, with evaporator coil descaling performed against −30 °C to +8 °C air-off. Chilled-water temperature rise stalls the pasteurising line
