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 forced-air pre-cooling systems in Jacobs
How fast can a technician service Güntner equipment at a potato & onion storage 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 forced-air pre-cooling systems 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 forced-air pre-cooling 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 forced-air pre-cooling systems performed against −1 °C to +4 °C air-off at high airflow. Condensation on bins causes rot spread through the stack
