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
Alfa Laval forced-air pre-cooling systems in Silverton
How fast can a technician service Alfa Laval 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 forced-air pre-cooling systems runs 24/7 because chilled-water temperature rise stalls the pasteurising line.
Do you stock OEM components for Alfa Laval systems?
Yes — Alfa Laval plate packs, gaskets and cleaning-in-place chemistry. Alfa Laval (Sweden) equipment on R717/R744/R404A 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 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 forced-air pre-cooling systems performed against −1 °C to +4 °C air-off at high airflow. Chilled-water temperature rise stalls the pasteurising line
