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

Evapco air curtain installation in Waltloo

How fast can a technician service Evapco 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 air curtain installation runs 24/7 because underground heat stress limits shift productivity.

Do you stock OEM components for Evapco systems?

Yes — Evapco spray nozzles, drift eliminators, fan drives and water treatment kits. Evapco (USA) equipment on R717/R744 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 air curtain installation 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 air curtain installation performed against Across −25 °C to +30 °C differentials. Underground heat stress limits shift productivity
