FAQ
Carel temperature mapping & validation in Wilsonia
How fast can a technician service Carel equipment at a potato & onion storage site in Wilsonia?
Wilsonia sits on the N2 and N6, so our East London dispatch reaches most Wilsonia Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because condensation on bins causes rot spread through the stack.
Do you stock OEM components for Carel systems?
Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on R404A 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 GLOBALG.A.P. documentation your auditors expect.
What operating envelope do you commission this equipment to?
Potato & Onion Storage run at +4 °C to +10 °C at 85–95% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Condensation on bins causes rot spread through the stack
