China Heat Preservation PU Sandwich Panel for Freezer Cold Room

Heat preservation PU sandwich panel for freezer cold room
Product introduction
PU sandwich panels is a kind of board used for enclosing structures, which has good heat insulation and higher intensity.it can reduce the heat transmission caused by difference in the internal and external temperature, and get to maximum efficiency of freezing and refrigeration systems. Designed scientifically and easy to use It is a new type of heat insulation material for lower construction cost. Panels are in multiple varieties and specifications to meet the need of various sites and projects. After tested by national authoritative testing organization, all technical indicators comply with national standards.

Application

PU foam panels are widely applicable to various low-temperature refrigeration storages, air conditioning storages, high-temperature storages and large logistics storages

structure introduction
1.substrate of the board: color steel, stainless steel, or rust-proof aluminum alloy plate(Customers can choose by their own needs). The metal panel and heat insulation core material are foamed, bonded and shaped at one time by Pu pressure injection machine, bringing higher storage board intensity and rigidly.

2. PU sandwich panel jointing

Generally, refrigeration storage boards are in protruding and grooving form. Our panels is jointed by the cam-lock, with the space between two boards sealed with sealing material.


The uppermost feature of PU refrigeration storage board is their connection ways, with a mazy-like-hard combined sealing to ensure high-level impermeability in refrigeration storages and low-temperature structures. They are also applicable to clean and super clean room.
