Aarhus University, Dept. of Chemistry and iNANO Center, intends to procure a helium liquifier system as an upgrade for an LOT-QuantumDesign PPMS. While its main function will be with said PPMS, the liquifier is further intended to support helijet applications (sample cooling) on the X-ray diffractometers commanded by the department. It is therefore a mobile unit. The liquefaction rate should be ca. 22 L/day. The system generally includes:
— Cryocooler and compressor.
— Production and storage dewar (160 L).
— Control computer and harness.
— Touch screen panel.
— Wheel set, access ports to helium.
