Local context
Working in Witfield
We service Witfield Industrial and the surrounding blocks of Witfield, Boksburg, with access off the N12 and R21. 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 freezer room construction in Witfield
How fast can a technician service Evapco equipment at a mining & bulk air cooling site in Witfield?
Witfield sits on the N12 and R21, so our Boksburg dispatch reaches most Witfield Industrial sites inside a standard callout window. Emergency freezer room construction 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 freezer room construction 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 freezer room construction performed against −18 °C to −25 °C room design. Underground heat stress limits shift productivity
