Gas liquefaction

Liquefaction made accessible for your process

Liquefiers partially or fully condense a given volume of gas.

Reducing the specific volume facilitates the storage and transportation of the product.

Our technology

We offer a unique technology enabling gas liquefaction through volumetric expansion.

Under equal conditions, the temperature drop and liquefaction rate surpass those of an equivalent expansion valve.

What we are offering you

Liquefaction on methanizer

At the outlet of the membranes, after purification, our technology allows for the liquefaction of biomethane without the need for an external supply of liquid nitrogen, without an auxiliary loop, and with an equipment reduction.


Our piston expander recovered a portion of the energy consumed during liquefaction.

The specific consumption depends on the pressure at the membranes and the required liquefaction pressure.
