L-Series

Standardized systems for small liquefaction capacities

Customers for small systems appreciate the L-Series as a safe, user-friendly system. Its’ reliability and high-quality equipment are particularly emphasized.

Linde provides standard helium liquefiers based on two different technologies:

  • turbine expander: highly reliable, low operation and maintenance cost
  • piston expander: cost efficient, easy installation

Performance variations are realized by different coldbox sizes, varying compressor sizes and using liquid nitrogen pre-cooling. All L-Series helium liquefiers include an internal freeze-out purifier to remove dry air contaminants from recovered helium.

 

Turbine Expander:

Linde Kryotechnik developed the L-Series equipped with turbine expanders (L70, L140, L280) especially to meet the needs of universities and research institutes with a liquid helium requirement of 20 to 290 Litre per hour.

 

Piston Expander:

The piston expanders (L1410, L1610 und L1620) of our sister company Linde Cryogenics broadens the product range for small liquefaction capacities.

The control system can be fitted with online access for supervisors or Linde’s service department.
