Local context
Working in Jet Park
We service Jet Park Industrial Estate and the surrounding blocks of Jet Park, Boksburg, with access off the R21 and N12 and N3. 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 Jet Park
How fast can a technician service Sabroe equipment at a mining & bulk air cooling site in Jet Park?
Jet Park sits on the R21 and N12 and N3, so our Boksburg dispatch reaches most Jet Park Industrial Estate 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
