Local context

Working in Chantelle

We service Chantelle Industrial and the surrounding blocks of Chantelle, Pretoria, with access off the R80 and R514. 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 humidity control systems in Chantelle

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

Chantelle sits on the R80 and R514, so our Pretoria dispatch reaches most Chantelle Industrial sites inside a standard callout window. Emergency humidity control systems 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 humidity control systems 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 humidity control systems performed against 45–95% RH depending on product. Underground heat stress limits shift productivity
