FAQ
Bitzer process chiller maintenance in Kathu Industrial
How fast can a technician service Bitzer equipment at a seafood processing & fisheries site in Kathu Industrial?
Kathu Industrial sits on the N14 and R380, so our Kathu dispatch reaches most Kathu Industrial sites inside a standard callout window. Emergency process chiller maintenance runs 24/7 because slow freezing forms large ice crystals and ruins texture.

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 process chiller maintenance 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 process chiller maintenance performed against −20 °C to +15 °C process supply. Slow freezing forms large ice crystals and ruins texture
