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

Sabroe plc & controller programming in Hermanstad

How fast can a technician service Sabroe equipment at a mining & bulk air cooling 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 plc & controller programming runs 24/7 because underground heat stress limits shift productivity.

Do you stock OEM components for Sabroe systems?

Yes — Sabroe valve kits, Unisab control boards and oil separators. Sabroe (Denmark) equipment on R717/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 plc & controller programming 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 MHSA documentation your auditors expect.

What operating envelope do you commission this equipment to?

Mining & Bulk Air Cooling run at +2 °C to +12 °C chilled water at 90–100% RH, with plc & controller programming performed against Full plant control range. Underground heat stress limits shift productivity
