FAQ
Bitzer variable speed drive installation in Rocky Drift
How fast can a technician service Bitzer equipment at a mining & bulk air cooling site in Rocky Drift?
Rocky Drift sits on the N4 and R40, so our White River dispatch reaches most Rocky Drift Industrial sites inside a standard callout window. Emergency variable speed drive installation runs 24/7 because underground heat stress limits shift productivity.
Do you stock OEM components for Bitzer systems?
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 variable speed drive installation 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 variable speed drive installation performed against Turndown to 30% of rated duty. Underground heat stress limits shift productivity
