Local context
Working in Rustivia
We service Rustivia Industrial and the surrounding blocks of Rustivia, Germiston, 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
Carel humidity control systems in Rustivia
How fast can a technician service Carel equipment at a vaccine cold chain facilities site in Rustivia?
Rustivia sits on the N3 and R24, so our Germiston dispatch reaches most Rustivia Industrial sites inside a standard callout window. Emergency humidity control systems runs 24/7 because loss of ultra-low storage destroys irreplaceable stock.
Do you stock OEM components for Carel systems?
Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on R134a/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 humidity control systems 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 humidity control systems performed against 45–95% RH depending on product. Loss of ultra-low storage destroys irreplaceable stock
