FAQ
Evapco controlled atmosphere installation in Rocky Drift
How fast can a technician service Evapco equipment at a potato & onion storage site in Rocky Drift?
Rocky Drift sits on the N4 and R40, so our White River dispatch reaches most Rocky Drift Industrial sites inside a standard callout window. Emergency controlled atmosphere installation runs 24/7 because condensation on bins causes rot spread through the stack.
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/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 GLOBALG.A.P. documentation your auditors expect.
What operating envelope do you commission this equipment to?
Potato & Onion Storage run at +4 °C to +10 °C at 85–95% RH, with controlled atmosphere installation performed against 1–3% O₂, 0–5% CO₂ at −0.5 °C to +2 °C. Condensation on bins causes rot spread through the stack
