Cold Room Panel Thickness Selection Guide for Different Storage Temperature

Cold Room Panel Thickness Selection Guide for Different Storage Temperature

Panel thickness is selected according to internal set temperature and local maximum ambient temperature; insufficient thickness leads to heavy power consumption and condensation. Medium temperature cold room (0~+8℃ fruit, vegetable, dairy preservation): standard 100mm PU panel, suitable for most temperate zones. Low temperature frozen storage (-18~-25℃): 120~150mm PU panel, widely used for meat, seafood frozen warehouse export projects. Blast freezer (-30~-40℃ rapid freezing): 150~200mm PU panel, large temperature difference requires thick insulation to control heat infiltration. High ambient tropical / Middle East project (max 45℃): upgrade one thickness level, e.g. medium temp uses 120mm instead of 100mm. Xiteliduo cold room PU panel HS 940600 provides thickness calculation sheet based on local ambient temperature and internal design temperature. Too thin panel will cause foam core inside joint to condensate, gradually foam rot, metal sheet bulge and insulation performance decline year by year. Too thick panel raises initial material cost; it is unnecessary for small temperature difference fresh keeping cold room and reduces usable space. Panel thickness cannot be increased after installation; thermal design must be confirmed before production and shipment. Cold room for ice storage needs special thick panel design, ice melting loss is extremely sensitive to heat infiltration. Refrigeration maintenance & repair company judges insufficient insulation if panel outer surface feels obviously cool in hot summer.
