Local context

Working in Ndabeni

We service Ndabeni Industrial and the surrounding blocks of Ndabeni, Cape Town, with access off the N2 and M5. Mediterranean summers with strong south-easters carry dust and salt onto condenser coils, and winter rain drives condensation risk at dock openings.

FAQ

Güntner evaporator coil descaling in Ndabeni

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

Ndabeni sits on the N2 and M5, so our Cape Town dispatch reaches most Ndabeni Industrial sites inside a standard callout window. Emergency evaporator coil descaling 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 evaporator coil descaling 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 evaporator coil descaling performed against −30 °C to +8 °C air-off. Moisture pickup drives rancidity and kernel downgrade
