01 LNG Gas cylinder machinery produaction line

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.
