FAQ
Carel temperature mapping & validation in Markman
How fast can a technician service Carel equipment at a supermarket central distribution site in Markman?
Markman sits on the N2 and R335, so our Gqeberha dispatch reaches most Markman Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because rack failure halts store replenishment across a region.
Do you stock OEM components for Carel systems?
Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on R404A/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?
Supermarket Central Distribution run at −25 °C to +12 °C multi-temp at 80–90% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Rack failure halts store replenishment across a region
