FAQ
Bock gas recharge & recovery in Nuffield
How fast can a technician service Bock equipment at a seafood processing & fisheries site in Nuffield?
Nuffield sits on the N17 and R29, so our Springs dispatch reaches most Nuffield Industrial sites inside a standard callout window. Emergency gas recharge & recovery 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 gas recharge & recovery 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 gas recharge & recovery performed against Charge weight per nameplate. Slow freezing forms large ice crystals and ruins texture
