The invention discloses a condenser for a bioreactor exhaust, comprising: an inlet (1) adapted to be fluidically connected to a bioreactor exhaust port (2), a cooling chamber (3; 103) fluidically connected to the inlet and via a filter device (4) to an outlet (5), a cooling conduit (6; 106) in contact with the cooling chamber, a heating conduit (7) in contact with the filter device and a vortex tube (8) arranged to convey a cold gas stream through the cooling conduit and to convey a hot gas stream through the heating conduit.

Embodiments are provided for a cooling fan that has a vortex tube, an air turbine, and one or more fan blades. The vortex tube is capable of being supplied with compressed air and splitting the compressed air into a cold stream and a hot stream. The cold stream can spins said air turbine with attached fan blades, causing said fan blades to spin and blow cold air.

Vortex Tubes and related methods of separating an airflow into a hot airflow and a cold airflow employ a secondary airflow inlet. A Vortex Tube includes a secondary airflow inlet that injects a swirling airflow aligned with a central region of the lumen of a circulating tube. The secondary airflow inlet includes a swirl generator that generates the vorticity of the swirling airflow. The injected swirling airflow increase the inner vortex strength thereby increasing the temperature difference between the hot airflow and the cold airflow.
