Local context
Working in Stanger Industrial
We service Stanger Industrial and the surrounding blocks of Stanger Industrial, KwaDukuza, with access off the N2 and R102. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ
Bitzer process chiller maintenance in Stanger Industrial
How fast can a technician service Bitzer equipment at a potato & onion storage site in Stanger Industrial?
Stanger Industrial sits on the N2 and R102, so our KwaDukuza dispatch reaches most Stanger Industrial sites inside a standard callout window. Emergency process chiller maintenance runs 24/7 because condensation on bins causes rot spread through the stack.
Do you stock OEM components for Bitzer systems?
Yes — Genuine Bitzer valve plates, gasket sets, oil pumps and OLC-D1 protection modules. Bitzer (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 process chiller maintenance 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 process chiller maintenance performed against −20 °C to +15 °C process supply. Condensation on bins causes rot spread through the stack
