Local context
Working in Isando
We service Isando Industrial and the surrounding blocks of Isando, Kempton Park, with access off the R21 and N12. 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 variable speed drive installation in Isando
How fast can a technician service Carel equipment at a refrigerated transport fleets site in Isando?
Isando sits on the R21 and N12, so our Kempton Park dispatch reaches most Isando Industrial sites inside a standard callout window. Emergency variable speed drive installation runs 24/7 because trailer failure in transit writes off a full load.
Do you stock OEM components for Carel systems?
Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on R404A/R134a 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 variable speed drive 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 SANS 10147 documentation your auditors expect.
What operating envelope do you commission this equipment to?
Refrigerated Transport Fleets run at −25 °C to +8 °C at 80–90% RH, with variable speed drive installation performed against Turndown to 30% of rated duty. Trailer failure in transit writes off a full load
