Liquid Nitrogen Auto-fill Pump for Efficient Cooling and Filling of Low Pressure Temperature Controlled Applications

Norhof manufactures LN₂ auto-fill systems. When LN₂ is required, a small overpressure (100 mBar) is generated by a small heater element in the LN₂ inside the Dewar. Liquid flows smoothly out of the system similar to water from a tap, without spilling, noise and vibrations, ensuring efficient and safe filling and level control in your LN₂ cooling application.

Norhof’s flagship system is the #900 series, which is fully programmable with several control options, based on one or two sensors in level or temperature.

Applications for the Norhof #900 series LN₂ auto-fill include: automatic LN2 filling system for FTIR; automatic filling system for DSC; automatic LN₂ filling system for TMA; LN₂ Cold Trap filling; LN₂ heat exchangers PID temperature control; Computer Controlled Freezing; Gas Chromatography; Temperature stages in microscopes.
