Local context
Working in Hermanstad
We service Hermanstad Industrial and the surrounding blocks of Hermanstad, Pretoria, with access off the R80 and R101. Highveld summers push afternoon ambients past 32 °C with heavy thunderstorm humidity, so condensers here are sized with a generous approach and cleaned before every summer.

FAQ
Alfa Laval process chiller maintenance in Hermanstad
How fast can a technician service Alfa Laval equipment at a reefer container depots site in Hermanstad?
Hermanstad sits on the R80 and R101, so our Pretoria dispatch reaches most Hermanstad Industrial sites inside a standard callout window. Emergency process chiller maintenance runs 24/7 because a failed pti holds the box and the booking.
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 R744/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 SANS 10147 documentation your auditors expect.
What operating envelope do you commission this equipment to?
Reefer Container Depots run at −30 °C to +12 °C at 80–90% RH, with process chiller maintenance performed against −20 °C to +15 °C process supply. A failed PTI holds the box and the booking
