FAQ
Güntner forced-air pre-cooling systems in Welkom Industrial
How fast can a technician service Güntner equipment at a macadamia processing site in Welkom Industrial?
Welkom Industrial sits on the N1 and R30, so our Welkom dispatch reaches most Welkom Industrial sites inside a standard callout window. Emergency forced-air pre-cooling systems 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 forced-air pre-cooling systems 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 forced-air pre-cooling systems performed against −1 °C to +4 °C air-off at high airflow. Moisture pickup drives rancidity and kernel downgrade
