FAQ

Carel data logging & alarm systems in Markman

How fast can a technician service Carel equipment at a potato & onion storage site in Markman?

Markman sits on the N2 and R335, so our Gqeberha dispatch reaches most Markman Industrial sites inside a standard callout window. Emergency data logging & alarm systems 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 data logging & alarm systems 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 data logging & alarm systems performed against Continuous logging at 1–15 minute intervals. Condensation on bins causes rot spread through the stack
