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

Jun 05 2019 Read 346 Times

Norhof releases a new way of cooling down to -186ºC with liquid Argon auto-fill systems. Liquid Argon (LAr) as a cooling medium is 10ºC warmer than LN2 but can take out about 2,3 times more heat per unit of mass than LN2. When LAr is required, a small overpressure (150 mBar) is generated by a small heater element in the LAr inside the Dewar. In a very elegant way liquid flows out of the system like water from a tap, without spilling, noise and vibrations, ensuring efficient and safe filling and level control in your cooling application.

The Norhof LAR #915 series, which is fully programmable with several control options, is based on one or two sensors in level or temperature.

Applications for the Norhof LAR #915 series Liquid Argon auto-fill include: automatic LAr filling system for FTIR; automatic LAr filling system for DSC; automatic LAr filling system for TMA; Liquid Argon Cold Trap filling; Liquid Argon heat exchangers PID temperature control; Computer Controlled Freezing; Gas Chromatography; temperature stages in microscopes.
