Name: Small integrated liquid nitrogen machine (cold head type)
Product name: Weidejie
Model: WDJ-195-10L-A
Daily output: 8L-15L
1. Manufacturing principle of liquid nitrogen machine
This product adopts a cold head refrigerator, and the low temperature cold head generated by the refrigerator is installed in the liquid nitrogen insulation tank, which can
Freeze dry nitrogen, and the minimum output gas temperature can reach -196°, which is safe and reliable.
The equipment has various alarm protection functions, high pressure, low pressure, compressor overheating, overcurrent, so that the equipment can be produced and run.
more secure and reliable.
2. Store the low-temperature condensed liquid nitrogen produced by the refrigerator in an insulating container, and the liquid nitrogen insulating tank is equipped with a pressure indicator,
Liquid nitrogen export pipe, liquid nitrogen output solenoid valve, pressure relief valve, temperature indication and other functions;
