Lab Scale Helium Recovery & Liquefaction

Features

1. Liquefaction rate: Over 22 L/day
2. Liquid storage capacity: 100–250 L (customizable)
3. Automated liquefaction process to reduce operator workload,
 enabled by:
 ・Optimized gas flow rate and pressure control
 ・High-precision helium purity monitor for impurity detection
 ・Integrated helium purifier
 ・Automatic liquid nitrogen supply
 ・Automatic purifier cleaning function
4. Designed for low-pressure applications up to +200 kPa (gauge)

How It Works: Smart Helium Handling

 ■ Helium gas is ingested from the user's recovery line into the system.
 ■ Impurities are removed by a liquid nitrogen trap (purifier).
 ■ Helium gas purity is monitored at ppm levels downstream of the purifier.
 ■ Upon detecting purifier contamination, the system automatically supplies helium to the liquefier from a clean second purifier.
 ■ The contaminated first purifier is heated and cleaned.
