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

Güntner cooling tower maintenance in Kew

How fast can a technician service Güntner equipment at a supermarket central distribution 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 cooling tower maintenance runs 24/7 because rack failure halts store replenishment across a region.

Do you stock OEM components for Güntner systems?

Yes — Güntner EC fan modules, defrost heaters and coil blocks. Güntner (Germany) equipment on R404A/R744/R448A 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 cooling tower 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?

Supermarket Central Distribution run at −25 °C to +12 °C multi-temp at 80–90% RH, with cooling tower maintenance performed against +28 °C to +40 °C condenser water. Rack failure halts store replenishment across a region
