To all who have responded to my questions, thank you for your inputs. They are highly appreciated. I'm thinking of just going with either Isocab or DC-system for the panels at 13.5m length (vertical installation) and 175mm thick for outside and 150mm for inside. Probably Frick compressors. I'm also looking at revising the layout from double deep to VNA. I'm looking at Linde K-series VNA trucks. Going with either SAP or Oracle for ERP and WMS. Hybrid RFID and barcode labelling.
