Local context
Working in Waltloo
We service Waltloo Industrial and the surrounding blocks of Waltloo, Pretoria, with access off the N4 and R104. 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 temperature mapping & validation in Waltloo
How fast can a technician service Sabroe equipment at a mining & bulk air cooling site in Waltloo?
Waltloo sits on the N4 and R104, so our Pretoria dispatch reaches most Waltloo Industrial sites inside a standard callout window. Emergency temperature mapping & validation 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 temperature mapping & validation 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 temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Underground heat stress limits shift productivity
