Local context
Working in Mossel Bay Industrial
We service Voorbaai Industrial and the surrounding blocks of Mossel Bay Industrial, Mossel Bay, with access off the N2 and R327. Mediterranean summers with strong south-easters carry dust and salt onto condenser coils, and winter rain drives condensation risk at dock openings.

FAQ
Carel temperature mapping & validation in Mossel Bay Industrial
How fast can a technician service Carel equipment at a data centre & critical cooling site in Mossel Bay Industrial?
Mossel Bay Industrial sits on the N2 and R327, so our Mossel Bay dispatch reaches most Voorbaai 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
