Local context

Working in Perseverance

We service Perseverance Industrial and the surrounding blocks of Perseverance, Gqeberha, with access off the N2 and R335. Coastal salt-laden air plus wide day-night temperature swings demand coated coils and tight vapour barriers.

FAQ

Carel plc & controller programming in Perseverance

How fast can a technician service Carel equipment at a reefer container depots site in Perseverance?

Perseverance sits on the N2 and R335, so our Gqeberha dispatch reaches most Perseverance Industrial sites inside a standard callout window. Emergency plc & controller programming runs 24/7 because a failed pti holds the box and the booking.

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 plc & controller programming 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 SANS 10147 documentation your auditors expect.

What operating envelope do you commission this equipment to?

Reefer Container Depots run at −30 °C to +12 °C at 80–90% RH, with plc & controller programming performed against Full plant control range. A failed PTI holds the box and the booking
