FAQ
Bock screw compressor service in Tzaneen Industrial
How fast can a technician service Bock equipment at a seafood processing & fisheries site in Tzaneen Industrial?
Tzaneen Industrial sits on the R71 and R36, so our Tzaneen dispatch reaches most Tzaneen Industrial sites inside a standard callout window. Emergency screw compressor service runs 24/7 because slow freezing forms large ice crystals and ruins texture.
Do you stock OEM components for Bock systems?
Yes — Bock shaft seals, suction filters and gasket kits. Bock (Germany) equipment on R404A/R717/R744 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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Seafood Processing & Fisheries run at −40 °C blast to −25 °C hold at 85–95% RH, with screw compressor service performed against −45 °C to +5 °C evaporating. Slow freezing forms large ice crystals and ruins texture
