Local context
Working in Silverton
We service Silverton Industrial, Waltloo and the surrounding blocks of Silverton, Pretoria, with access off the N4 and R104. 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 temperature mapping & validation in Silverton
How fast can a technician service Carel equipment at a refrigerated transport fleets site in Silverton?
Silverton sits on the N4 and R104, so our Pretoria dispatch reaches most Silverton Industrial sites inside a standard callout window. Emergency temperature mapping & validation 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 temperature mapping & validation 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 temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Trailer failure in transit writes off a full load
