MVE Auto LN2 Tank Switcher
The MVE automated supply tank switch is a dual inlet manifold enabling automatic switch to back-up supply for cryogenic storage tanks. Two liquid cylinders connect via the switching manifold directly to the nitrogen freezer. When the primary tank is empty, the supply line is automatically switched to the secondary or back-up cylinder.
This unattended switching ensures that supply integrity is maintained to the storage system. A visual alarm shows when the primary tank has been switched. Audible and visual alarms indicate to laboratory personnel when both tanks are empty.
The tank switch operates by monitoring pressure in the transfer line, indicating both the demand for and supply of liquid nitrogen. This method eliminates the necessity for hardwired electrical connections to the cryogenic freezer control system, avoiding the potential for electrical interference and simplifying installation. Although designed primarily for cryogenic freezers, the tank switch can be utilized to supply any device using liquid nitrogen to supply any device using liquid nitrogen at low pressure and at a rate similar to liquid nitrogen freezers.
