Local context
Working in Rosslyn
We service Rosslyn Automotive Hub, Rosslyn Industrial Park, Babelegi and the surrounding blocks of Rosslyn, Pretoria, with access off the N4 and R80 Mabopane Freeway and R566. 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 co₂ transcritical service in Rosslyn
How fast can a technician service Bock equipment at a seafood processing & fisheries site in Rosslyn?
Rosslyn sits on the N4 and R80 Mabopane Freeway and R566, so our Pretoria dispatch reaches most Rosslyn Automotive Hub sites inside a standard callout window. Emergency co₂ transcritical 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 co₂ transcritical 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 co₂ transcritical service performed against −35 °C evaporating, 90–120 bar high side. Slow freezing forms large ice crystals and ruins texture
