FAQ
Evapco controlled atmosphere installation in Witbank Industrial
How fast can a technician service Evapco equipment at a seafood processing & fisheries site in Witbank Industrial?
Witbank Industrial sits on the N4 and N12, so our eMalahleni dispatch reaches most Witbank Industrial sites inside a standard callout window. Emergency controlled atmosphere installation runs 24/7 because slow freezing forms large ice crystals and ruins texture.
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/R404A 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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Seafood Processing & Fisheries run at −40 °C blast to −25 °C hold at 85–95% RH, with controlled atmosphere installation performed against 1–3% O₂, 0–5% CO₂ at −0.5 °C to +2 °C. Slow freezing forms large ice crystals and ruins texture
