FAQ
Carel temperature mapping & validation in De Aar Industrial
How fast can a technician service Carel equipment at a data centre & critical cooling site in De Aar Industrial?
De Aar Industrial sits on the N10 and N12, so our De Aar dispatch reaches most De Aar Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because thermal runaway trips racks within minutes.
Do you stock OEM components for Carel systems?
Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on R134a/R744 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 ASHRAE TC9.9 documentation your auditors expect.
What operating envelope do you commission this equipment to?
Data Centre & Critical Cooling run at +18 °C to +27 °C supply air at 40–60% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Thermal runaway trips racks within minutes
