The Self-pressurized Series is designed to store and supply liquid nitrogen by using the pressure generated from the vapourisation of a small amount of LN2. This allows the liquid to be discharged into other containers through a dedicated hose without an external pressurization source.

All models use welded stainless steel construction, labelled valves for easy identification, and a 5-year vacuum warranty. The official page states that all models include a safety valve, while 200 L models and above also include an additional rupture disc.

The technical sheet adds that all models feature four casters for mobility, and each unit includes a pressure valve, drain valve, relief valve, and pressure gauge. K-series models add the DLZ-300 digital level gauge, remote data transmission capability, and a pressure-stabilizing valve for compatible auto-filling configurations
