120Liters per day mixed-refrigerant liquid nitrogen plant
Product Profile
Scala produces a wide range of LNS series liquid nitrogen plant from 80 to 2400 liters per day , or larger custom sizes. Our nitrogen liquifier uses advanced mixed refrigerants (MR) cryocooler combined with Joule-thompson (JT) refrigeration system to liquify nitrogen at cost effective way.
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 liquid nitrogen plant 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.
Application areas
Food frozen
Blood and stem cell sample storage
Metal treatment (rapid cooling)
Bottled water production
