Product overview

Phu Son supplies the complete modular cold store: insulated wall and ceiling panels, cold store doors and the BK Cool industrial refrigeration unit — one point of contact for all three.

The 2026 catalogue lists 6 standard store sizes for two product groups: WCB uses R134 refrigerant for produce (vegetables, roots and fruit) at -5°C, and WFB uses R404 for fresh food (fish, meat and seafood) at -29°C. Beyond the standard sizes, stores are designed to the project’s actual dimensions.
