Local context
Working in Silverton
We service Silverton Industrial, Waltloo and the surrounding blocks of Silverton, Pretoria, with access off the N4 and R104. Highveld summers push afternoon ambients past 32 °C with heavy thunderstorm humidity, so condensers here are sized with a generous approach and cleaned before every summer.

FAQ
Bitzer co₂ transcritical service in Silverton
How fast can a technician service Bitzer equipment at a dairy processing plants site in Silverton?
Silverton sits on the N4 and R104, so our Pretoria dispatch reaches most Silverton Industrial sites inside a standard callout window. Emergency co₂ transcritical service runs 24/7 because chilled-water temperature rise stalls the pasteurising line.
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/R744/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 co₂ transcritical service 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?
Dairy Processing Plants run at +2 °C to +4 °C at 80–85% RH, with co₂ transcritical service performed against −35 °C evaporating, 90–120 bar high side. Chilled-water temperature rise stalls the pasteurising line
