Specification




Features

Outer Material

The main body is made of aluminum alloy plate, which is light in weight, high in strength and corrosion resistant.

Heat insulator

The multi-layer heat insulator uses aluminum foil with excellent reflective performance as reflective screen and uses materials with small thermal conductivity and low outgassing rate as the hear insulating material.

Vacuum layer

The vacuum layer is in a high vacuum state, and an adsorbent with a large adsorption capacity is used to ensure the long-term stability and reliability of the container performance.

Composition

The aluminum alloy liquid nitrogen container is mainly composed of an out shell, and inner tank, a neck tube, a multi-layer insulation body, a bucket, etc.

Inner Material

The container shell and liner are made of aluminum alloy plate, which has the characteristics of light weight, high strength at low temperature and corrosion resistance.

The neck tube

The neck tube possesses characteristics of high mechanical strength and low thermal.

More Features

  • ・Low LN2 consumption
  • ・High strength, low weight aluminum construction
