FAQ
Carel humidity control systems in Lydenburg Industrial
How fast can a technician service Carel equipment at a macadamia processing site in Lydenburg Industrial?
Lydenburg Industrial sits on the R37 and R36, so our Mashishing dispatch reaches most Lydenburg Industrial sites inside a standard callout window. Emergency humidity control systems runs 24/7 because moisture pickup drives rancidity and kernel downgrade.

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
