Local context

Working in Kew

We service Kew Industrial and the surrounding blocks of Kew, Johannesburg, with access off the M1 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 electrical panel upgrades in Kew

How fast can a technician service Bitzer equipment at a mining & bulk air cooling site in Kew?

Kew sits on the M1 and N3, so our Johannesburg dispatch reaches most Kew Industrial sites inside a standard callout window. Emergency electrical panel upgrades runs 24/7 because underground heat stress limits shift productivity.

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 R134a/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 electrical panel upgrades 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 MHSA documentation your auditors expect.

What operating envelope do you commission this equipment to?

Mining & Bulk Air Cooling run at +2 °C to +12 °C chilled water at 90–100% RH, with electrical panel upgrades performed against 400 V 3-phase plant duty. Underground heat stress limits shift productivity
