Helium recondenser - HeRL

Liquefaction rates from 10 to 60 liters per day
Zero boil-off solution (no evaporation loss)

Helium recondensers (HeRL) offer the possibility of transforming your open-cycle system into a closed-cycle, zero-loss (zero boil-off) system. HeRLs recondense helium vapors from the evaporation of liquid helium from cryostats.

purification

produits_ligne_20

Up to 99.9995% purification
Automatic & Cryogen-free (Pulse-Tube)

Contrairement aux épurateurs refroidis à l’azote liquide qui nécessitent un remplissage hebdomadaire et une régénération mensuelle du piège, l’épurateur automatique fonctionne et se régénère automatiquement sans aucune intervention de l’utilisateur. 

Le système comprend un analyseur de gaz qui mesure la pureté de l’hélium en sortie de l’épurateur et déclenche un cycle de régénération avant que les contaminants ne puissent en sortir.

Absolut System offers systems based on robust, reliable two-stage scroll (or spiro-orbital) compression technology. They offer compression up to 27 bar for a flow rate of 212 SLPM (12.7 m3/h).

Helium recovery and management systems designed to fit your space and your needs. Absolut System can help you define your needs and design your complete helium recovery and liquefaction system.

Automatique & Sans cryogène (Pulse-Tube)

Unlike liquid nitrogen-cooled scrubbers, which require weekly refilling and monthly regeneration of the trap, the automatic scrubber operates and regenerates automatically without any user intervention.

The system includes a gas analyzer that measures the purity of the helium leaving the scrubber and triggers a regeneration cycle before contaminants can leave.
