What are the characteristics of liquid nitrogen filling machine?

1. low speed, no tank without interval filling mode, reduce liquid nitrogen loss, reduce operating costs. At high speed, the filling valve is always open, and the automatic detection is carried out at high and low speed. 2. vacuum insulation protection, reduce operating costs. 3. liquid gas separator ensures that liquid nitrogen is in an ultra cold state and improves the purity of liquid phase, making the filling more precise and stable. 4. liquid nitrogen buffer function, effectively control li
