Local context
Working in Letsitele
We service Letsitele packhouse precinct and the surrounding blocks of Letsitele, Tzaneen, with access off the R71 and R529. Long, hot lowveld summers regularly exceed 36 °C, so high-ambient head pressure control and shaded plant rooms are non-negotiable.

FAQ
Alfa Laval evaporator coil descaling in Letsitele
How fast can a technician service Alfa Laval equipment at a macadamia processing site in Letsitele?
Letsitele sits on the R71 and R529, so our Tzaneen dispatch reaches most Letsitele packhouse precinct 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
