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) broadens the product range for small liquefaction capacities.
The control system can be fitted with online access for supervisors or Linde’s service department.
