FAQ

Isocab freezer room construction in Silverton

How fast can a technician service Isocab equipment at a seafood processing & fisheries 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 freezer room construction runs 24/7 because slow freezing forms large ice crystals and ruins texture.

Do you stock OEM components for Isocab systems?

Yes — Isocab panel joints, door sets and hygienic coving. Isocab (Belgium) equipment on R404A/R717/R744 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 freezer room construction 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 freezer room construction performed against −18 °C to −25 °C room design. Slow freezing forms large ice crystals and ruins texture
