80L per day mixed refrigerant liquid nitrogen generator

80Liters per day mixed-refrigerant liquid nitrogen generator

Product Profile

Scala produces a wide range of LNS series liquid nitrogen generators  from 80 to 2400 liters per day , or larger custom sizes. Our liquid nitrogen system uses advanced mixed refrigerants (MR) cryocooler combined with Joule-thompson (JT) refrigeration systems.

The LNS liquid nitrogen system has higher liquefaction efficiency and improved reliability compared with traditional GM cold head and Stirling refrigerator.  The use of standard refrigerant components are accessible.

Feature and Benefis

Advanced mixed-refrigerant cooling system with proprietary technology, compared with the traditional Stirling and GM cooler, the refrigerator does not need regular maintenance,it has high reliability and long service life.

Integrated modular type adsorption dryer and filtration system to ensure only clean and extremely dry compressed air flows into the nitrogen system and avoid freezing inside the cryo-cooler. With energy saving function,the dryer can be linked with air compressor.

World recognized nitrogen membrane from Parker, it has highest separation efficiency, no need electric heater,nitogen purity is 99%.  Parker membrane modules are the most robust in the world and when provided with correct pre-treatment,life expectancy can exceed 10 years. Additionally, Parker membrane modules allow compressors to operate at 5 to 13barg,which incresase flexibility for the whole liquid nitrogen system, no nitrogen booster is required . 

Pry-mounted structure, only need to connect the pipeline,the system can run automatically, on-site installation is greatly reduced, it has smaller size and  low noise.

All cryogenic fittings are vacuum type to reduce cooling loss.

Applications

Food frozen
Blood and stem cell sample storage
Metal treatment (rapid cooling)
Bottled water production
Aerospace
Liquid nitrogen fracturing
Rocket thrust
Infrared cooling
Superconductors

Technical Specifications

Note: 

1. Other voltages on request.

2. Higher ambient temperature on request.

3. High altitude on request.

Efficient use method of liquid nitrogen generator:
1. You must wear work clothes and labor protection articles as required by the job.
2. The experimenter must earnestly study nitrogen safety knowledge and safety operation rules training, and only after passing the qualification can they be put into operation. Those who fail the training shall not operate without permission.
3. Maintain ventilation in the laboratory. Outside temperature 10～30℃, relative humidity 50%～60%. Avoid vibration and direct sunlight. Do not place flammable materials near the instrument to reduce the concentration of flammable, explosive and other harmful gases to prevent The accident happened.
4. Before the liquid nitrogen plant is used, the equipment must be thoroughly inspected.
5. Before initial use or reconnecting the chromatograph, the instrument must be self-checked to check whether the plug, power cord, etc. are intact, and can only be used after passing the self-test.
6. Check the electrolyte level before turning on the instrument. When the electrolyte level is close to the lower limit, make up water in time, and do not exceed the upper limit water level when adding water.
