Liquid Switch

Liq-Switch — Intelligent Liquid Nitrogen Switching for Cryogenic Continuity

Ensuring Uninterrupted LN₂ Supply for Critical Cryogenic and Biobank Applications

Liq-Switch is Ambra Sistemi’s advanced solution for the automatic management and switching of liquid nitrogen (LN₂) sources, designed to guarantee continuous and stable supply in cryogenic installations where temperature integrity and operational continuity are essential.

Engineered for biobanks, laboratories, research facilities and cryogenic storage applications, Liq-Switch automatically manages the transition between primary and reserve dewars, ensuring uninterrupted LN₂ flow without pressure instability or manual intervention.

The system continuously monitors pressure, supply status and consumption, generating immediate alarms and notifications in case of anomalies, depletion or abnormal operating conditions, protecting sensitive biological and research materials from temperature excursions.

Smart switching. Continuous supply. Secure cryogenic environments.

Complete In-House Design and Production

Liq-Switch is conceived, engineered, assembled, and tested entirely within Ambra Sistemi facilities. This guarantees exceptional reliability, rapid technical support, and long-term availability of components and spare parts for critical cryogenic applications.

Safe and Uninterrupted LN2 Supply

Liq-Switch automatically manages the switching between primary and reserve liquid nitrogen dewars, ensuring a safe and continuous LN2 supply without pressure fluctuations or manual intervention, protecting temperature-sensitive materials.

Seamless Integration with Monitoring Infrastructure

Liq-Switch can be easily installed within existing gas distribution infrastructures and connected to external supervision systems through alarm signals, monitoring interfaces and control networks.

Reduced Costs and Increased Operational Efficiency

Automated source switching, continuous monitoring and centralized system control reduce manual operations, optimize liquid nitrogen usage and minimize downtime in cryogenic installations.
