Local context
Working in Mkondeni
We service Mkondeni Industrial and the surrounding blocks of Mkondeni, Pietermaritzburg, with access off the N3 and R56. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ
Evapco controlled atmosphere installation in Mkondeni
How fast can a technician service Evapco equipment at a vaccine cold chain facilities site in Mkondeni?
Mkondeni sits on the N3 and R56, so our Pietermaritzburg dispatch reaches most Mkondeni Industrial sites inside a standard callout window. Emergency controlled atmosphere installation runs 24/7 because loss of ultra-low storage destroys irreplaceable stock.
Do you stock OEM components for Evapco systems?
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 SAHPRA GDP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Vaccine Cold Chain Facilities run at +2 °C to +8 °C and −20 °C / −70 °C at 45–60% RH, with controlled atmosphere installation performed against 1–3% O₂, 0–5% CO₂ at −0.5 °C to +2 °C. Loss of ultra-low storage destroys irreplaceable stock
