FAQ
Bitzer co₂ transcritical service in Markman
How fast can a technician service Bitzer equipment at a seafood processing & fisheries site in Markman?
Markman sits on the N2 and R335, so our Gqeberha dispatch reaches most Markman 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 Bitzer systems?
Yes — Genuine Bitzer valve plates, gasket sets, oil pumps and OLC-D1 protection modules. Bitzer (Germany) equipment on R404A/R744/R717 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
