FAQ
Evapco cold room construction in Rocky Drift
How fast can a technician service Evapco equipment at a table grape packhouses 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 cold room construction runs 24/7 because slow pull-down causes so₂ pad burn and berry shatter.
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 cold 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 PPECB documentation your auditors expect.
What operating envelope do you commission this equipment to?
Table Grape Packhouses run at −0.5 °C to +1 °C at 90–95% RH, with cold room construction performed against −2 °C to +12 °C room design. Slow pull-down causes SO₂ pad burn and berry shatter
