FAQ
Bitzer energy retrofit & optimisation in Hamilton
How fast can a technician service Bitzer equipment at a macadamia processing site in Hamilton?
Hamilton sits on the N1 and N8, so our Bloemfontein dispatch reaches most Hamilton Industrial sites inside a standard callout window. Emergency energy retrofit & optimisation runs 24/7 because moisture pickup drives rancidity and kernel downgrade.
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/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 energy retrofit & optimisation 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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Macadamia Processing run at +8 °C to +15 °C at 55–65% RH, with energy retrofit & optimisation performed against Plant-wide kWh reduction of 15–35%. Moisture pickup drives rancidity and kernel downgrade
