FAQ

Güntner hydrocooler installation in Wilsonia

How fast can a technician service Güntner equipment at a potato & onion storage site in Wilsonia?

Wilsonia sits on the N2 and N6, so our East London dispatch reaches most Wilsonia Industrial sites inside a standard callout window. Emergency hydrocooler installation runs 24/7 because condensation on bins causes rot spread through the stack.

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 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 hydrocooler installation performed against +0.5 °C to +2 °C water temperature. Condensation on bins causes rot spread through the stack
