Local context
Working in Nasrec
We service Nasrec Industrial and the surrounding blocks of Nasrec, Johannesburg, with access off the N1 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 temperature mapping & validation in Nasrec
How fast can a technician service Carel equipment at a wineries & wine cellars site in Nasrec?
Nasrec sits on the N1 and N12, so our Johannesburg dispatch reaches most Nasrec Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because fermentation temperature spikes strip aroma compounds.
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?
Wineries & Wine Cellars run at +8 °C to +16 °C at 70–80% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Fermentation temperature spikes strip aroma compounds
