Local context
Working in Knights
We service Knights Industrial and the surrounding blocks of Knights, Germiston, with access off the N17 and N3. 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
Bitzer energy retrofit & optimisation in Knights
How fast can a technician service Bitzer equipment at a seafood processing & fisheries site in Knights?
Knights sits on the N17 and N3, so our Germiston dispatch reaches most Knights Industrial sites inside a standard callout window. Emergency energy retrofit & optimisation 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 energy retrofit & optimisation 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 energy retrofit & optimisation performed against Plant-wide kWh reduction of 15–35%. Slow freezing forms large ice crystals and ruins texture
