Name: Nitrogen liquefaction machine (refrigerator)
Product name: Sheng Dejie
Model: WDJ-YH-40L
Daily output: 40L
1. Technical scheme:
The nitrogen liquefaction machine adopts the principle of throttling refrigeration of mixed working medium, and cools nitrogen from ambient temperature to the saturation condensation temperature of nitrogen liquefaction step by step. The liquid nitrogen is stored in the liquid nitrogen tank, and 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 refrigeration compressor adopts German semi-hermetic 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;

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 liquefied gas industry.
