FAQ

Bitzer variable speed drive installation in Upington Industrial

How fast can a technician service Bitzer equipment at a mining & bulk air cooling site in Upington Industrial?

Upington Industrial sits on the N10 and N14, so our Upington dispatch reaches most Upington Industrial sites inside a standard callout window. Emergency variable speed drive installation runs 24/7 because underground heat stress limits shift productivity.

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
