SELECTION OF COLD STORAGE PANEL

Empty white storage unit with a sliding door inside a warehouse with metal walls and a concrete floor.

Polyurethane panel with the variety of available external plating (SII, PVC-coated steel,Stainless steel) guarantees the heat insulation performance of cold storage.This helps maintain the desired storage temperature despite the huge difference between the internal and external environment,ensuring equipment working efficiency,making it energy-saving in the long run.

Panels made of polyurethane (PU) are strong but lightweight. Depending on their thickness, PU panels can sustain extremely cold temperatures.

ADVANTAGES OF POLYURETHANE INSULATED PANELS

Polyurethane offers great structural strenght per length

Offers a great R value to expanded polysterene per thickness.

  • Excellent insulating efficiency over a wide temperature range.

  • When heated or melted, polyurethane does not melt.

  • Polyurethane does not cause flames to spread within a fire or increase the intensity of an existing fire.

  • Moisture resistance and water repellent.

CUSTOMIZED COLD STORAGE PANEL

Specification for Customized PU Panel

PU panel standard width is 1.00m , with height ranging from 1.50mH to 11.50mH. PU panels can be tailored according to client’s requirement.

Features a designated camlock system attachment to ensure panels are attached securely.

Sandwich panels are composed of two exterior layers of pre-painted, 0.5mm steel with a polyurethane core that insulates the panel from heat and sound.

  Polyurethane panel thickness offered are the following:

AUTOMATIC POLYURETHANE (PU) PANELS

Automatic, continuous production lines that integrate multiple pieces of technology enable the efficient and large-scale manufacturing of sandwich PU panels. These lines automate the process of forming, uncoiling, and precisely dispensing and foaming a polyurethane (PU) core. The completed panel is then heated, pressed, and cut to size. Thermal insulation, structural longevity, and constant product quality are guaranteed by this high level of automation.

Thermal Insulati on Efficiency

Dimensional Stability

Mechanical Strength

PIR

  • Excellent

  • Hard to ignite(B1)

  • Forms a dense,protective char layer upon fire exposure,effectively resisting flame spread and high-temperature penetration

  • Superior

  • Lower long-term thermal conductivity(typically≤0.022 W/m.k).

  • Provides more durable and stable insulation,leading to better energy savings over time

  • Advanced

  • More stable molecular structure,wider temperature tolerance range.

  • Less prone to shrinkage or deformation due to temperature fluctuations,maintaining panel integrity long-term and preventing thermal bridges.

  • Maximum Strenght

  • At the same density, PIR foam generally has higher compressive and bending strength than PUR.

  • Results in a more rigid and durable panel.

PUR

  • GOOD

  • Hard to ignite(B2)

  • Has good flame retardancy,but its charring ability and fire resistance are inferior to PIR

  •  Exceptional

  • Excellent insulation properties(thermal conductivity typically ≤0.023-0.026W/m.k).

  • A traditionally high-performance insulating material

  • Quality

  • Offers good dimensional stability.

  • However,long-term stability under extreme cyclic temperatures is slightly lower than PIR

  • Up to satisfactory

  • Mechanical strength is sufficient for the vast majority of cold storage applications.
