Local context

Working in Jacobs

We service Jacobs Industrial and the surrounding blocks of Jacobs, Durban, with access off the N2 and M4. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ

Güntner hydrocooler installation in Jacobs

How fast can a technician service Güntner equipment at a table grape packhouses site in Jacobs?

Jacobs sits on the N2 and M4, so our Durban dispatch reaches most Jacobs Industrial sites inside a standard callout window. Emergency hydrocooler installation runs 24/7 because slow pull-down causes so₂ pad burn and berry shatter.

Do you stock OEM components for Güntner systems?

Yes — Güntner EC fan modules, defrost heaters and coil blocks. Güntner (Germany) equipment on R404A/R717 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 hydrocooler 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 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 hydrocooler installation performed against +0.5 °C to +2 °C water temperature. Slow pull-down causes SO₂ pad burn and berry shatter
