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 airfreight perishable handling 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 ramp exposure breaks the chain before uplift.

Do you stock OEM components for Evapco systems?

Yes — Evapco spray nozzles, drift eliminators, fan drives and water treatment kits. Evapco (USA) equipment on 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 IATA PCR documentation your auditors expect.

What operating envelope do you commission this equipment to?

Airfreight Perishable Handling run at +2 °C to +8 °C at 85–90% RH, with freezer room construction performed against −18 °C to −25 °C room design. Ramp exposure breaks the chain before uplift
