Local context
Working in Cornubia
We service Cornubia Industrial and Business Estate and the surrounding blocks of Cornubia, Durban, with access off the N2 and M41. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.
Rapid 4-hour pull-down windows after field heat arrival Slow pull-down causes SO₂ pad burn and berry shatter

FAQ
Isocab blast freezer installation in Cornubia
How fast can a technician service Isocab equipment at a table grape packhouses site in Cornubia?
Cornubia sits on the N2 and M41, so our Durban dispatch reaches most Cornubia Industrial and Business Estate sites inside a standard callout window. Emergency blast freezer installation runs 24/7 because slow pull-down causes so₂ pad burn and berry shatter.
Do you stock OEM components for Isocab systems?
Yes — Isocab panel joints, door sets and hygienic coving. Isocab (Belgium) equipment on R404A/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 blast freezer installation 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 PPECB documentation your auditors expect.
What operating envelope do you commission this equipment to?
Table Grape Packhouses run at −0.5 °C to +1 °C at 90–95% RH, with blast freezer installation performed against −35 °C to −40 °C air-off. Slow pull-down causes SO₂ pad burn and berry shatter
