FAQ
Bitzer process chiller maintenance in Mahikeng Industrial
How fast can a technician service Bitzer equipment at a mining & bulk air cooling site in Mahikeng Industrial?
Mahikeng Industrial sits on the N18 and R49, so our Mahikeng dispatch reaches most Mahikeng Industrial sites inside a standard callout window. Emergency process chiller maintenance runs 24/7 because underground heat stress limits shift productivity.

Yes — Genuine Bitzer valve plates, gasket sets, oil pumps and OLC-D1 protection modules. Bitzer (Germany) equipment on R134a/R744/R717 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 process chiller maintenance 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 process chiller maintenance performed against −20 °C to +15 °C process supply. Underground heat stress limits shift productivity
