Local context
Working in Sebenza
We service Sebenza Industrial and the surrounding blocks of Sebenza, Edenvale, with access off the N3 and R24. 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 controlled atmosphere installation in Sebenza
How fast can a technician service Evapco equipment at a data centre & critical cooling site in Sebenza?
Sebenza sits on the N3 and R24, so our Edenvale dispatch reaches most Sebenza Industrial sites inside a standard callout window. Emergency controlled atmosphere installation runs 24/7 because thermal runaway trips racks within minutes.

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 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 ASHRAE TC9.9 documentation your auditors expect.
What operating envelope do you commission this equipment to?
Data Centre & Critical Cooling run at +18 °C to +27 °C supply air at 40–60% RH, with controlled atmosphere installation performed against 1–3% O₂, 0–5% CO₂ at −0.5 °C to +2 °C. Thermal runaway trips racks within minutes
