Local context
Working in Modimolle Industrial
We service Modimolle Industrial and the surrounding blocks of Modimolle Industrial, Modimolle, with access off the N1 and R33. Long, hot lowveld summers regularly exceed 36 °C, so high-ambient head pressure control and shaded plant rooms are non-negotiable.

FAQ
Evapco controlled atmosphere installation in Modimolle Industrial
How fast can a technician service Evapco equipment at a mining & bulk air cooling site in Modimolle Industrial?
Modimolle Industrial sits on the N1 and R33, so our Modimolle dispatch reaches most Modimolle Industrial sites inside a standard callout window. Emergency controlled atmosphere 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 controlled atmosphere 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 controlled atmosphere installation performed against 1–3% O₂, 0–5% CO₂ at −0.5 °C to +2 °C. Underground heat stress limits shift productivity
