Local context
Working in Waltloo
We service Waltloo Industrial and the surrounding blocks of Waltloo, Pretoria, with access off the N4 and R104. 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 Waltloo
How fast can a technician service Carel equipment at a third-party cold storage (3pl) site in Waltloo?
Waltloo sits on the N4 and R104, so our Pretoria dispatch reaches most Waltloo Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because a single plant outage puts several clients' stock at risk.
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 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?
Third-Party Cold Storage (3PL) run at −25 °C to +4 °C at 85–90% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. A single plant outage puts several clients' stock at risk
