Local context
Working in Driehoek
We service Driehoek Industrial and the surrounding blocks of Driehoek, Germiston, with access off the N3 and N17. 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 Driehoek
How fast can a technician service Carel equipment at a retail store refrigeration site in Driehoek?
Driehoek sits on the N3 and N17, so our Germiston dispatch reaches most Driehoek Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because cabinet failure during trading hours writes off displayed stock.
Do you stock OEM components for Carel systems?
Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on R744/R448A 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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Retail Store Refrigeration run at −22 °C to +6 °C at 50–60% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Cabinet failure during trading hours writes off displayed stock
