FAQ
Alfa Laval process chiller maintenance in De Aar Industrial
How fast can a technician service Alfa Laval equipment at a macadamia processing site in De Aar Industrial?
De Aar Industrial sits on the N10 and N12, so our De Aar dispatch reaches most De Aar Industrial sites inside a standard callout window. Emergency process chiller maintenance 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 process chiller maintenance 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 process chiller maintenance performed against −20 °C to +15 °C process supply. Moisture pickup drives rancidity and kernel downgrade
