FAQ

Bock screw compressor service in Waltloo

How fast can a technician service Bock equipment at a wineries & wine cellars site in Waltloo?

Waltloo sits on the N4 and R104, so our Pretoria dispatch reaches most Waltloo Industrial sites inside a standard callout window. Emergency screw compressor service runs 24/7 because fermentation temperature spikes strip aroma compounds.

What pressure testing and gas compliance certificates are provided?

Every screw compressor service 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 SANS 10147 documentation your auditors expect.

What operating envelope do you commission this equipment to?

Wineries & Wine Cellars run at +8 °C to +16 °C at 70–80% RH, with screw compressor service performed against −45 °C to +5 °C evaporating. Fermentation temperature spikes strip aroma compounds
