FAQ
Carel temperature mapping & validation in Ermelo Industrial
How fast can a technician service Carel equipment at a table grape packhouses site in Ermelo Industrial?
Ermelo Industrial sits on the N2 and N17, so our Ermelo dispatch reaches most Ermelo Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because slow pull-down causes so₂ pad burn and berry shatter.
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 PPECB documentation your auditors expect.
What operating envelope do you commission this equipment to?
Table Grape Packhouses run at −0.5 °C to +1 °C at 90–95% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Slow pull-down causes SO₂ pad burn and berry shatter
