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
Isocab blast freezer installation in Witfield
How fast can a technician service Isocab 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 blast freezer installation runs 24/7 because ramp exposure breaks the chain before uplift.
Do you stock OEM components for Isocab systems?
Yes — Isocab panel joints, door sets and hygienic coving. Isocab (Belgium) 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 blast freezer 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 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 blast freezer installation performed against −35 °C to −40 °C air-off. Ramp exposure breaks the chain before uplift
