The unit is equipped with a membrane contactor for nitrogenation. The internal fibres of the membrane contactor form a large contact area between the gas and beverage, ensuring instant and efficient dissolution. The applied N² pressure enables control of the final N² concentration in the beverage. 

Optionally an additional membrane contactor can be used to remove CO². This is useful for a beverage with higher CO² concentration or a beverage where a specific CO²/N² concentration is required. The removal of CO² is set by the level of vacuum applied to the decarbonation membrane contactor. 

The unit is typically installed between two BBTs. The centrifugal pump transfers beverage from the first tank into the unit at constant pressure, temperature and flow. The outlet valve is used control the required beverage pressure and flow. The treated beverage is then pushed to the next tank.
