FAQ
Bock co₂ transcritical service in Bethlehem Industrial
How fast can a technician service Bock equipment at a seafood processing & fisheries site in Bethlehem Industrial?
Bethlehem Industrial sits on the N5 and R26, so our Bethlehem dispatch reaches most Bethlehem Industrial 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
