Overview

The LN20-AC is a convenient, cost-effective, ready-to-operate cryogenic solution for on-site applications. Its small form factor, minimal power requirements, and independence from cooling water or water chillers position it as the superior choice in the market.

The system’s integrated cooling mechanism ensures operational capability in ambient temperatures up to 32°C, rendering it adaptable to many climatic conditions. For conditions up to 52°C, we recommend our LN20 water-cooled version.

Operation is as simple as connecting the generator and pressing start. The intelligent level sensors facilitate the automatic production of LN2 as and when required. The produced LN2 is securely stored within an appropriately sized vacuum-insulated tank. Dispensing is facilitated through a provided 1.5-meter vacuum-insulated hose, with alternative dispensing methods available upon request.
