FAQ
Alfa Laval packhouse chiller maintenance in Hamilton
How fast can a technician service Alfa Laval equipment at a seafood processing & fisheries 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 packhouse chiller maintenance runs 24/7 because slow freezing forms large ice crystals and ruins texture.
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 packhouse 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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Seafood Processing & Fisheries run at −40 °C blast to −25 °C hold at 85–95% RH, with packhouse chiller maintenance performed against −1 °C to +8 °C room design. Slow freezing forms large ice crystals and ruins texture
