Modular Cold Room Polyurethane Insulation Panel (PU Panel)

General info about our cold room polyurethane panel

We are a professional supplier & exporter of  prefab polyurethane insulation modular cold room panel of walk-in cooler panel and walk-in freezer panel in China. Various sizes of best quality cold room panels for walk-in cooler and walk-in freezer are available for the installation of walk-in coolers & walk-in freezers. The joint design of the modular coldroom panel is made with tongue and groove edges and are locked together with cam lock design fasteners built in the sandwich panel.  Cold room designer and manufacturer can easily assemble and install the cold rooms by themselves. Or when users want to move the walk-in cooler or walk-in freezer to another place, the cold room panels of polyurethane foaming panel (PUF panel) can be easily disassembled with a hex wrench and re-installed.  The prefab modular fabrication cold room panel is made of different dimensions which makes it quite flexible for constructing different sizes of walk-in cold store plant and refrigerated machinery warehouse.  All cold store plant & equipment sandwich panels are injected with 100% high density polyurethane foaming material with an average density of 40kg/m3 firmly glued to the metal surfaces (optional precoated cold rolled steel sheet, embossed aluminum sheet, stainless steel sheet) for perfect sealing of refrigerated warehouse & walk-in cold rooms. We have two options of insulation panel material which can be full polyurethane panel (100% PUF panel) or XPS + PU panel(composite panel). The XPS + PU panel is our factory's unique foaming technology to make the excellent insulation efficiency and make much more cost saving on price. 

Cam Lock Design for Coldroom Panel

Cold Room Panel Joint & Sealing

Walk-in Cooler & Freezer Cam Lock Walk-in Freezer & Cooler Gasket

1. Walk-in freezer & cooler Modular polyurethane panel construction

Panels are joined together by means of tongue and groove and locked together by camlock on each side of the panel to ensure air tight joints.
  * High density thermo insulated panel up to 40kg/m3 or above for perfect cold-room heat insulation efficiency
  * Low flammable PU foaming material is used in the coldroom panel
  * Cam-lock design fastener to install cold room tightly and strongly for most convenient cold room installation
  * Magnetic gaskets are used on the panel edge of the joint parts of each sandwich panel to ensure perfect sealing to avoid the cooling air leakage from the cool room or moisture inside the PU insulated panel for the best refrigeration and frozen storage result
  * Multiple types of optional thermo insulated panel cold room doors (Convex hinged door/Hinged door/Sliding door) with customized door size
