A standard cold storage setup comprises two primary subsystems: the thermal enclosure and the refrigeration system. 1. Thermal Insulation Enclosure PU Panels: Polyurethane (PU) sandwich panels featuring cam-lock mechanisms or tongue-and-groove joints for tight sealing. Typical densities range between 40-42kgs/m³ Panel Thickness Guidelines: Chiller Room(0 to 5℃): 75mm to 100mm panels; Freezer Room(-18 to -25℃): 120mm to 150mm panels Blast Freezer Room(-35 to -40℃): 200mm
