FAQ

Güntner cooling tower maintenance in Kathu Industrial

How fast can a technician service Güntner equipment at a macadamia processing site in Kathu Industrial?

Kathu Industrial sits on the N14 and R380, so our Kathu dispatch reaches most Kathu Industrial sites inside a standard callout window. Emergency cooling tower maintenance runs 24/7 because moisture pickup drives rancidity and kernel downgrade.

Do you stock OEM components for Güntner systems?

Yes — Güntner EC fan modules, defrost heaters and coil blocks. Güntner (Germany) equipment on R404A/R134a 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?

Macadamia Processing run at +8 °C to +15 °C at 55–65% RH, with cooling tower maintenance performed against +28 °C to +40 °C condenser water. Moisture pickup drives rancidity and kernel downgrade
