What Our Customers Say

Lisa
Medical Assistant
"As a medical service center, we need stable and reliable LN2 supply to support application of our equipment. LNS generator has been one of our most trusted products. It never fails our liquid nitrogen demand. Big thumb up!!"

Tin
Professor
"We have a set of observation apparatus at a remote place which is abusolutely no liquid gas station. Thanks to Scala's on site liquid nitrogen generator we can keep our equipment work at very good conditions."

Michael
Cattleman
"Cryopreservation is crucial to keep our selective breeding of good varieties samples. Before we have co-operation with Scala, we never know there could be such a convevient and reliable liquid nitrogen supply unit. Highly recommend!"
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.
