Local context
Working in Knights
We service Knights Industrial and the surrounding blocks of Knights, Germiston, with access off the N17 and N3. 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 pipework & lagging in Knights
How fast can a technician service Evapco equipment at a vaccine cold chain facilities site in Knights?
Knights sits on the N17 and N3, so our Germiston dispatch reaches most Knights Industrial sites inside a standard callout window. Emergency pipework & lagging 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 pipework & lagging 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 pipework & lagging performed against −45 °C to +120 °C line temperatures. Loss of ultra-low storage destroys irreplaceable stock
