Liquid Nitrogen Auto-fill Pump for Low Pressure Cooling and Filling of 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
