SCALA LNS Series Liquid Nitrogen Generators are innovative, plug-and-play solutions designed for laboratories, researching institutions and medical centers. These compact, oil-free air compressor, PSA nitrogen generator, cryo-cooler, and vacuum dewar tank systems provide automated on-site nitrogen production and storage. Controlled by PLC, they generate liquid nitrogen efficiently within hours, with minimal maintenance.
Liquid Nitrogen Components
Featuring with GM and pulse tube cryo-cooler, innovative PSA nitrogen generator, and built-in liquid level gauge, Scala liquid nitrogen generators ensure reliable, long-term performance with low operational costs and easy monitoring. One-click dispensing simplifies usage, with automatic start and standby.
1. Oil-free Air Compressor
Built-in high performance GAST or THOMAS oil-free air compressor, CE & UL certified, complies with global regulations and longer working time.
100% Contaminant-Free Air: Critical for food & beverage, pharmaceuticals, electronics, and medical applications.
Low Noise: Typically reduces noise by 10–30 dB(A), ideal for compliance with workplace noise regulations.
Lower Maintenance: Double cooling fans beside the compressor further extend the service life.
2. PSA Nitrogen Generator
Unlike other brands, Scala liquid nitrogen generators come with PSA nitrogen gas generation system, which means customer do not have to out source nitrogen gas to have independent liquid nitrogen supply.
With high-strength non-welde aluminum adsorption towers with maximum 16 bar-g working pressure, significantly eliminates nitrogen contamination and reducing leakage during liquefication.
3. Large Built-in Dewar
The built-in dewar performs very important role in liquid nitrogen producing. It provides a vacuum insulated room for cryocooler to make ultra-low temperature for nitrogen gas liquefication.
Most LN2 generator manufacturers only provide very small dewar tank to cast costs which cannot meet users' real needs.
Large dewar also means the generator can store more liquid nitrogen for customer applicants. If the dewar is too small it barely can provide enough liquid nitrogen to cool down applicants and perform.
4. Reliable Cryocooler for Nitrogen Liquefication
We apply the cutting-edge hybrid Stirling cyrocoolers and GM cryocoolers in scientific researching appliants to make on-site liquid nitrogen generators. With decades of using experience and EU, CE & American UL certification, GM cryocoolers have been proved reliable and safety throughout the world.
Pulse Tube Cryocoolers (PTCs) are advanced, reliable, and efficient systems with unique design, which eliminates moving parts in the cold section, provides significant benefits in terms of durability, low vibration, and noise, making them ideal for sensitive and critical applications.
Gifford-McMahon (GM) Cryocooler's high thermodynamic efficiency makes it quickly reaches to the 77K low temperature for nitrogen gas liquefication.
Key Features
When other brands' liquid nitrogen generators rely on manual oversight and guesswork, leading to wasted resources and operational inefficiencies, Scala team has developed cutting-edge products with innovative technologies to delivery unmatched operating experience.
1. Smart Liquid Nitrogen Level Control
We utilize high sensitive digital level gauge with decades using experience to measure the liquid nitrogen level in the dewar tank, which enables our liquid nirogen generators automatic start & standby according to liquid nitrogen volume pre set.
The settable liquid nitrogen ratio control means you always have enough liquid nitrogen for your applications.
10'' HMI control panel will also display the liquid nitrogen level so you do not have to guess how much liquid nitrogen you have inside the dewar.
2. High Purity Nitrogen 99.95%~99.997%
The high performance CMS (carbon molecular sieves) adsorbent inside the towers, with average diameter 0.9mm, crush strength ≥ 35N and water content 1±0.5%, featuring with high nitrogen production rate, low air-nitrogen ratio and low ash content, make our nitrogen purity easily reach to 99.95%~99.997%.
With built-in nitrogen purity analyzer, users can also read the purity on the HMI.
3. Ultra Clean Liquid Nitrogen
Scala brand liquid nitrogen generators are pre-installed with dust removal filters with removal precision ＜0.01 μm to make sure only clean nitrogen gas will be liquiefied.
High standard sterilization filters are optional to ensure sterile nitrogen gas before liquiefication for specific field or requirements. The DRYPOINT® M PLUS diffused drying membrane pack with built-in nanoscale filter cartridge provides innovative solution for high standard liquid nitrogen treatment.
4. Pilot Solenoid Valves
Solenoid valves play important role in controlling the nitrogen gas to be pressured into the dewar tank for liquefication and also in liquid nitrogen dispensing.
The independent four-way solenoid valves increase times efficency to ensure long-term trouble-free operation.
Pilot solenoid valve used for drainage has service life more than 1,000,000 times.
Qualified CE & UL certification, and a switch with a suppressor extends longer service life.
5. Easy Liquid Nitrogen Dispense
When most generators in the market adopts manually dispensing, the globe valve is easily frozen and you have to wait for at least 15 minutes for another dispense.
LNS series comes with cryo solenoid valve dispensing outlet which saves the process of turning off the machine or pressure building process. Press the touch screen and the liquid nitrogen will be dispensed easily and at controllable volume needed.
Dispensing duration is also settable and dispensing stops automatically when time is up (say 300 seconds).
6. Industrial-grade Electrical System
LNS series are powered by Siemens® PLC controller, solid state relays, and world-class electrical components from Schneider®, Weidmüller®, ABB® etc to make sure the reliability of the systems we build.
All models are additionally equipped with physical switches, emergency stops, and buzzer alarms to meet the needs of users in different industries and countries.
7. Weincloud Monitor for Reliability
Equipped with WeinView® WiFi module, CMT Viewer and EasyAccess 2.0 exclusive remote connection, eliminate firewall or router settings, the liquid nitrogen generators obtain the remote connection service in 5 minutes to do remote monitoring and trouble-shooting any time any where.
You can also choose the most suitable monitoring modeamong cMT Vierwer mobile device monitoring, WebView web monitoring, and VNC Viewer.

FAQ
Q: What is the lead time of production?
A: Lead time depends on what type you order and your special requirements. Normally we can deliver LNS liquid nitrogen generator in 6-8 weeks after we receive deposit.
Q: Do we need additional equipments to operate LNS series liquid nitrogen generator?
A: No additional equipment is required. LNS series are highly compact units. You just need connect the machine to required power supply and it will generate liquid nitrogen automatically.
Q: What should I do once the liquid nitrogen is produced?
A: LNS series have built-in liquid nitrogen tanks inside the cabinet. Once the liquid nitrogen is generated, it will be storaged in the tanks. Once the liquid nitrogen level reaches the pre-set level in side the tanks, the machine will standby automatically. And once the liquid level is below the pre-set level, the machine will start work and produce liquid nitrogen until it reaches the pre-set level.
Q: How to dispense the liquid nitrogen in the tank?
A: LNS series equiped with both solenoid valve and manually globe valve. When liquid nitrogen is needed, you can dispense the liquid nitrogen to cryopreservation container or self-pressuring tank by click of the HMI screen.
Q: Can we choose specific color of the cabinet door?
A: Absolutely! We understand that choosing the right color is an important decision. Besides, we can provide ODM and OEM and many more customized services.
Q: Do you offer any warranties on your LNS series?
A: Yes, we stand behind the quality of our liquid nitrogen generators and offer warranties on manufacturing defects. If you encounter any issues with your generators due to manufacturing defects, please contact us, and we'll work with you to resolve the issue promptly.
