LNG Cylinder Machinery Production Line LNG process constant low temperature
1:LNG Gas Cylinder Machinery Production Line Liquefied Natural Gas, Constant Temperature
The LNG cylinder production line of EN source company is used to store liquefied natural gas.
As we all know, liquefied natural gas is the most environmentally friendly and clean energy in the world,
but the transportation and storage of natural gas is relatively difficult,
and it needs to maintain a constant temperature or cryogenic(low temperature) environment.
The LNG projects provided by our company perfectly solve this problem.

LNG cylinder vacuum system:
The internal heating and vacuuming system is mainly used for heating and vacuuming the interlayer of LNG cylinders for automobiles. The internal heating system is used to heat the inner bladder of the LNG cylinder to a certain temperature, and the heat is achieved through hot air exchange. The gas cylinder uses an external electric heater to generate heat, and the hot air is heated by a fan into the inner liner of the gas cylinder. In the vacuum heating and degassing process of the system, a multi-stage vacuum system composed of molecular pumps and Rhodes pumps is used to vacuum heating and degassing low-temperature containers to ensure the degassing during the vacuum heating and degassing of LNG cylinders for automobiles.
