Local context
Working in Polokwane Industrial
We service Polokwane Industrial, Superbia and the surrounding blocks of Polokwane Industrial, Polokwane, with access off the N1 and R71. Long, hot lowveld summers regularly exceed 36 °C, so high-ambient head pressure control and shaded plant rooms are non-negotiable.

FAQ
Güntner evaporator coil descaling in Polokwane Industrial
How fast can a technician service Güntner equipment at a macadamia processing site in Polokwane Industrial?
Polokwane Industrial sits on the N1 and R71, so our Polokwane dispatch reaches most Polokwane 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
