Next-Generation Liquid Nitrogen Generator Powered by GM Cryo-cooler
In the global market for on site liquid nitrogen generators, the GM (Gifford-McMahon) cryo-cooler is the dominant technology, accounting for over 95% of sales. Prized for its stable refrigeration performance based on the principle of gas adiabatic expansion, GM cryo-coolers are essential in critical fields like NMR, quantum communication, medical care and semiconductors.
Based on this advanced technology, Scala developed LNS20A liquid nitrogen generator with a daily output of 20 to 50 liters, offering a versatile solution adaptable to various user scenarios.
Details
Design Philosophy
Modern Industrial Appearance: Simple and clean white color scheme built with sturdy composite material, providing protection and durability.
Interface and Controls: 10'' colored Siemens® HMI with power indicator and emergency stop designed for easy access and operation.
Mobility: Mounted on FOOT MASTER® castors allows easy movement, facilitating its relocation as per requirements.
Ergonomic Reference: Human-centric design considerations for interfaces or access points with 1750mm height.
Lifting Holes: Provide secure anchor points to prevent slippage or imbalance during tranporation and installation.
Gifford-McMahon (GM) Cryocooler
High Efficiency Refrigeration: High thermodynamic efficiency makes it quickly reaches to the 77K low temperature for nitrogen gas liquefication.
Compact and Portable: The cold head is designed compact, occupying small space, which allows Scala liquid nitrogen generator overall in small footprint.
Reliable Operation: With mature technology for decades, it has high reliability and can be used in industrial and scientific research scenarios while keep stable performance.
Convenient Maintenance: Phase - adjusting device in the cryocooler reduces refrigeration performance caused sealing ring which greatly extends the maintenance cycle and service life.
CE & UL Certified: GM cryocoolers have been proved reliable and safety throughout the world
100-Liter Vacuum Insulated Dewar
Mounted Struture: The vertical dewar mounted by cryocooler at the top significantly improves the liquefication performance.
Lower LN2 Vaporization: The cold head at the top keeps the liquid nitrogen at liquefication temperature, reducing the waste caused by evaporation.
Maintenance Free: Lifespan more than 10 years, which means no need for replacement throughout its entire life cycle.
Super Large Volume: Built-in 100 liters volume dewar that can meet most using senarios without external LN2 tanks.
Helium Compressor
Designed for Cryogenic Systems: Engineered to work with closed-loop GM (Gifford-McMahon) cryocooler with to provide cryogenic temperature for nitrogen gas liquefaction.
High Helium Purity: Over 99.999% high purity helium is critical to avoid contamination of the cold head and ensure efficient heat transfer for faster and more nitrogen liquefaction.
Reasonable Maintenance Intervals: 3-Year maintenance interval significantly lower cost of ownership and reduced downtime compared with compressors requiring frequent servicing.
Broad Operating Range: Designed for wide cryogenic ambient temperature ranges (5–35 °C) and storage environments (down to −20 °C), useful in diverse laboratory and industrial environments.
