Local context
Working in Knights
We service Knights Industrial and the surrounding blocks of Knights, Germiston, with access off the 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

How fast can a technician service Bitzer equipment at a seafood processing & fisheries site in Knights?
Knights sits on the N17 and N3, so our Germiston dispatch reaches most Knights Industrial sites inside a standard callout window. Emergency compressor overhaul runs 24/7 because slow freezing forms large ice crystals and ruins texture.

What pressure testing and gas compliance certificates are provided?
Every compressor overhaul 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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
