Local context

Working in Pinetown

We service Pinetown Industrial, New Germany and the surrounding blocks of Pinetown, Durban, with access off the N3 and M13. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ

Carel humidity control systems in Pinetown

How fast can a technician service Carel equipment at a macadamia processing site in Pinetown?

Pinetown sits on the N3 and M13, so our Durban dispatch reaches most Pinetown Industrial sites inside a standard callout window. Emergency humidity control systems runs 24/7 because moisture pickup drives rancidity and kernel downgrade.

Do you stock OEM components for Carel systems?

Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) 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 humidity control 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 humidity control systems performed against 45–95% RH depending on product. Moisture pickup drives rancidity and kernel downgrade
