Scals is a leading manufacturer of all-in-one liquid nitrogen generators in China adopting advanced GM & Pulse Tube Cryo-cooler technologies.

Since the first sale of the an imported LN2 generator in 2017, Scala has always been guided by user needs and has carried out in-depth improvements and reshaping of the "liquid nitrogen generator". SCALA's LN2 generators come with self-developed PSA N2 production technique and integrate cryogenic technology with LN2 output ranging from 10 to 300 liters/day, purity as high as 99.5% ~ 99.999%, serving a wide range of industries and applications.

LN2 doser is the most effective process for inerting food & beverage containers to achieve desired oxygen exclusion. Delicate products filled into bottles/cans/jars should have very little contact with oxygen.

At Scala we provide Cryovbs-200 and Cryovbs-300 multi-purpose liquid nitrogen (LN2) dosing systems utilizing advanced cryogenic technology and PLC programming. The ultra-efficient systems are revolutionize packaging machine, ideal for many applications from inductory to high-speed requirements, significantly enhance packaging quality and cost saving.

Scala brand vacuum insulated hoses are designed to minimize thermal losses and prevent condensation during cryo fluids transfer, ideal for applications requiring the transfer of liquid nitrogen or other cryogens, ensuring that the liquid remains at low temperatures during transfer.

The static vacuum insulated hose is manufactured from 304 stainless steel, evacuated to a high vacuum of 10-6 mbar (10-4 Pa) with a vacuum pump. The hoses are available in 3 standard inner diameter sizes: 0.394" (Model DN10), 0.625" (Model DN15) and 1.25" (Model DN25).

SYDZ self-pressuring liquid nitrogen tanks under Scala brand are multi-layer insulated high vacuum tanks for liquid nitrogen storage & dispensing. Adpot advanced technologies, the tanks are manufactured under standards of IS9001: 2015 and strictly tested by quality assurance system.

SYDZ are widely used for storage and transportation of liquid nitrogen in aerospace, experimental and electronic instruments, food processing, mechanical manufacturing devices in various industries.
