Local context

Working in Dube TradePort

We service Dube TradePort SEZ, Dube AgriZone and the surrounding blocks of Dube TradePort, La Mercy, with access off the N2 and King Shaka corridor. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ

Güntner glycol chiller installation in Dube TradePort

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

Dube TradePort sits on the N2 and King Shaka corridor, so our La Mercy dispatch reaches most Dube TradePort SEZ sites inside a standard callout window. Emergency glycol chiller installation 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 glycol chiller installation 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 glycol chiller installation performed against −8 °C to +4 °C glycol supply. Moisture pickup drives rancidity and kernel downgrade
