Local context

Working in Selby

We service Selby Industrial and the surrounding blocks of Selby, Johannesburg, with access off the M2 and N17. 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 Selby

How fast can a technician service Güntner equipment at a retail store refrigeration site in Selby?

Selby sits on the M2 and N17, so our Johannesburg dispatch reaches most Selby Industrial sites inside a standard callout window. Emergency cooling tower maintenance runs 24/7 because cabinet failure during trading hours writes off displayed stock.

Do you stock OEM components for Güntner systems?

Yes — Güntner EC fan modules, defrost heaters and coil blocks. Güntner (Germany) equipment on 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?

Retail Store Refrigeration run at −22 °C to +6 °C at 50–60% RH, with cooling tower maintenance performed against +28 °C to +40 °C condenser water. Cabinet failure during trading hours writes off displayed stock
