Local context

Working in Linbro Park

We service Linbro Business Park and the surrounding blocks of Linbro Park, Sandton, with access off the N3 and M1. 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 Linbro Park

How fast can a technician service Sabroe equipment at a mining & bulk air cooling site in Linbro Park?

Linbro Park sits on the N3 and M1, so our Sandton dispatch reaches most Linbro Business Park 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
