Uncover secrets: PIR cold storage panel V.S. PUR handmade panel


 

In the world of cold storage, choosing the right insulation is crucial. PIR and PUR show major differences in how they're made, how well they work, and how efficient they are. Let's explore why LION CROWN is at the forefront of this transformation.

Pioneering Innovation in Cold Storage Panels

LION CROWN, a leader in PU sandwich panels, is reshaping the industry with cutting-edge solutions. LION CROWN focuses on making PU panels for cold storage, walls, and roofs. They make sure their products save energy, are kind to the environment, and last a long time. This reflects their belief: "Lion Crown makes the best panels and comes out on top."

The company is situated in Zhaoqing City, Guangdong Province, and it has two completely automatic production lines for making polyurethane sandwich panels. These lines include a 42-meter-long double-belt hot pressing machine, which is one of the longest of its kind in China.This advanced setup guarantees superior foam density, adhesive strength, and insulation performance.

Machine-Made vs. Hand-Made Panels

Traditional hand-made panels rely on outdated manual methods, leading to inconsistent quality, poor adhesion, and reduced insulation. By contrast, LION CROWN’s automated production line delivers:

·Uniform Foam Density: Ensures enhanced insulation and structural integrity.

·Efficient Production: A single line produces up to 12,000 square meters daily.

·Superior Performance: Achieves a thermal conductivity as low as 0.019W/mK.

Safety First: Flame Resistance That Saves Lives

LION CROWN uses PIR foam, engineered at the molecular level for flame retardancy. The material has been certified as B1-grade, meaning it can put itself out when the flame is taken away. This is different from regular PU foam, which has a hard time reaching the same level of fire safety. Sad events, like the fires at "Hangzhou Ice and Snow World" and in Shanghai, really show how important it is to use materials that don't catch fire easily.

Insulation Matters: Energy Efficiency and Cost Savings

Poor insulation can lead to temperature instability, higher energy costs, and compromised product safety. LION CROWN’s panels feature a 97% closed-cell rate, minimizing heat exchange and ensuring optimal energy efficiency.

Traditional Methods Fall Short

Manual foaming techniques in traditional panels often lead to uneven density, hollow spaces, and weaker performance. Thermal conductivity ranges from 0.022 to 0.026W/mK, compared to LION CROWN’s superior 0.019W/mK.

Meeting the Demands of Large-Scale Projects

With intelligent, computer-controlled production, LION CROWN ensures error-free, high-quality panels at scale. Unlike manual methods, which are slow and labor-intensive, LION CROWN’s technology delivers rapid turnaround for medium to large projects.

Choose the Best for Your Cold Storage Needs

No matter if you value saving energy, staying safe, or being efficient, LION CROWN's PIR cold storage panels are the top pick in the industry.
