Local context
Working in City Deep
We service City Deep Fresh Produce Market, City Deep Container Terminal and the surrounding blocks of City Deep, Johannesburg, with access off the M2 and N17 and N3. 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
Bock screw compressor service in City Deep
How fast can a technician service Bock equipment at a craft breweries site in City Deep?
City Deep sits on the M2 and N17 and N3, so our Johannesburg dispatch reaches most City Deep Fresh Produce Market sites inside a standard callout window. Emergency screw compressor service runs 24/7 because a stalled crash cool ruins a fermentation batch.
Do you stock OEM components for Bock systems?
Yes — Bock shaft seals, suction filters and gasket kits. Bock (Germany) equipment on R404A/R134a/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 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?
Craft Breweries run at −4 °C to +12 °C at 60–70% RH, with screw compressor service performed against −45 °C to +5 °C evaporating. A stalled crash cool ruins a fermentation batch
