Local context
Working in Cornubia
We service Cornubia Industrial and Business Estate and the surrounding blocks of Cornubia, Durban, with access off the N2 and M41. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ
Alfa Laval evaporator coil descaling in Cornubia
How fast can a technician service Alfa Laval equipment at a macadamia processing site in Cornubia?
Cornubia sits on the N2 and M41, so our Durban dispatch reaches most Cornubia Industrial and Business Estate 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 Alfa Laval systems?
Yes — Alfa Laval plate packs, gaskets and cleaning-in-place chemistry. Alfa Laval (Sweden) 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
