Local context

Working in Jacobs

FAQ

Bock refrigerant retrofit & compliance in Jacobs

How fast can a technician service Bock equipment at a seafood processing & fisheries site in Jacobs?

Jacobs sits on the N2 and M4, so our Durban dispatch reaches most Jacobs Industrial sites inside a standard callout window. Emergency refrigerant retrofit & compliance 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 refrigerant retrofit & compliance 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 refrigerant retrofit & compliance performed against Per replacement gas envelope. Slow freezing forms large ice crystals and ruins texture
