Local context
Working in Modderfontein
We service Modderfontein Industrial and the surrounding blocks of Modderfontein, Johannesburg, with access off the N3 and R25. 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 Modderfontein
How fast can a technician service Bitzer equipment at a craft breweries site in Modderfontein?
Modderfontein sits on the N3 and R25, so our Johannesburg dispatch reaches most Modderfontein Industrial sites inside a standard callout window. Emergency energy retrofit & optimisation runs 24/7 because a stalled crash cool ruins a fermentation batch.
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/R134a/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 SANS 10147 documentation your auditors expect.
What operating envelope do you commission this equipment to?
Craft Breweries run at −4 °C to +12 °C at 60–70% RH, with energy retrofit & optimisation performed against Plant-wide kWh reduction of 15–35%. A stalled crash cool ruins a fermentation batch
