1. Manufacturing principle: 

Liquid nitrogen generator (liquid nitrogen machine) equipment consists of nitrogen generator (built-in or external), refrigeration equipment (gas liquefaction equipment) and Dewar tank. The whole machine has a one-key start-up automatic refilling function. When the liquid nitrogen in the liquid nitrogen tank is lower than the set liquid level, the device automatically starts. The manufacture of liquid nitrogen machine adopts the principle of throttling refrigeration of mixed working medium, which cools nitrogen from ambient temperature to the saturation condensation temperature of nitrogen liquefaction step by step. To store in the liquid nitrogen tank to obtain liquid nitrogen, the equipment automatically detects the liquid nitrogen level in the Dewar tank, and automatically controls the operation of the equipment.

Second, the main configuration:

1. The compressor adopts German fully enclosed refrigeration compressor;

2. Liquid nitrogen level sensor: Mike automation instrument;

3. Dewar: Weidejie.

4. Electric control part: PLC

5. Independently design and develop human-machine interface control system

6. Refrigeration accessories are all world-renowned brands: Japan Saginata solenoid valve, Danfoss throttle valve,

Danvers filter, etc.;

7. PT100 platinum resistance and T-type thermocouple are used for temperature detection, both of which have high reliability and long-term stability.

life characteristics;

3. Technical parameters:

Main technical performance parameters of WDJ-LN-15L small liquid nitrogen machine equipment

Fourth, equipment advantages:

1. Our liquefaction system uses advanced mixed refrigerant (MR) refrigerant.

2. Compared with the traditional GM machine cold head, the mixed refrigerant compression refrigeration system has the characteristics of high reliability and long service life without regular maintenance.

3. All cryogenic pipe fittings are all vacuum insulated pipes to reduce the loss of cooling capacity.

4. Touch-type color Chinese and English operation interface.

5. The equipment has the function of automatic rehydration.

Five, industry application:

         Suitable for laboratory, food addition and stem cells, fertilized eggs and embryos in animal husbandry
