FAQ
Güntner evaporator coil descaling in Secunda Industrial
How fast can a technician service Güntner equipment at a macadamia processing site in Secunda Industrial?
Secunda Industrial sits on the N17 and R546, so our Secunda dispatch reaches most Secunda Industrial Complex 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
