Vacuum Insulation Technology

How Double-Wall Vacuum Works

Double-wall vacuum insulation uses a vacuum layer between two stainless steel walls to prevent heat transfer. This technology keeps beverages hot or cold for extended periods without external condensation.

Key Components:

Inner Wall: Food-grade 304 stainless steel
Vacuum Layer: 0.3-0.5mm gap with <0.001 Pa pressure
Outer Wall: 304 or 316 stainless steel
Copper Plating (Optional): Enhances heat reflection
