Low Temperature Gas or Liquid Supply System (LTSS)

ltss-ornl97-1_1The Low Temperature Gas or/and Liquid Transfer or Supply System (LTSS) is designed to provide a controllable flow of single phase, constant low temperature gas or liquid cryogen. Optional Control Package allows a computer to measure pressure, liquid level and to control the flow of cryogen to the use point.

The typical LTSS System is composed of:

  • Low Temperature Supply System (LTSS)
  • Cryostat (Optional)
  • Superinsulated Transfer Line or Superinsulated Bi-Directional
  • Transfer Line (Optional)
  • Instrument Support Module (Optional) (See Abbess Instruments literature for additional information on optional equipment)


  • Magnetic Susceptibility
  • High Speed NMR Gyros
  • Temperature Dependent Process
  • Chemical Testing
  • Gamma Test Cells
