LTHMFL - Helium Liquefier

 

For more than 20 years CTN hosts the unique general helium liquefier support facility in Portugal for materials science.
Since its installation in 1991, it has been continuously supplying different cryogenic equipments at this Campus and in other outside research institutions, especially in the Lisbon area.
The original system based on a Sulzer TCF20, turbine liquefier with a 1000 l reservoir and a nominal capacity of 10 l/hr without pre-cooling or 20 l/hr with liquid nitrogen pre-cooling, was in 2010 replaced by a new Linde L70 liquefier with a 2300 l reservoir and a nominal capacity of 27 l/hr without pre-cooling or 47 l/hr with liquid nitrogen pre-cooling.
