Local context

Working in Kelvin

We service Kelvin Industrial and the surrounding blocks of Kelvin, Sandton, with access off the N3 and M1. 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 humidity control systems in Kelvin

How fast can a technician service Carel equipment at a craft breweries site in Kelvin?

Kelvin sits on the N3 and M1, so our Sandton dispatch reaches most Kelvin Industrial sites inside a standard callout window. Emergency humidity control systems runs 24/7 because a stalled crash cool ruins a fermentation batch.

Do you stock OEM components for Carel systems?

Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on R404A/R134a 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 humidity control 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 SANS 10147 documentation your auditors expect.

What operating envelope do you commission this equipment to?

Craft Breweries run at −4 °C to +12 °C at 60–70% RH, with humidity control systems performed against 45–95% RH depending on product. A stalled crash cool ruins a fermentation batch
