Local context

Working in Witfield

We service Witfield Industrial and the surrounding blocks of Witfield, Boksburg, with access off the N12 and R21. 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

Güntner glycol chiller installation in Witfield

How fast can a technician service Güntner equipment at a craft breweries site in Witfield?

Witfield sits on the N12 and R21, so our Boksburg dispatch reaches most Witfield Industrial sites inside a standard callout window. Emergency glycol chiller installation runs 24/7 because a stalled crash cool ruins a fermentation batch.

Do you stock OEM components for Güntner systems?

Yes — Güntner EC fan modules, defrost heaters and coil blocks. Güntner (Germany) equipment on R404A/R717/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 glycol chiller installation 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 glycol chiller installation performed against −8 °C to +4 °C glycol supply. A stalled crash cool ruins a fermentation batch
