The climate module (1A, 1B) takes in ambient air (A) during the adsorption mode (M1), and the airflow generator (19) forces the intaken ambient air (A) through the adsorber unit (25) for dehumidifying the ambient air (A) and guides the dehumidified ambient air (A) via the outlet (6) and the inlet (7) of the battery housing (3) into the battery housing (3) during the adsorption mode (M1). The climate module (1A, 1B) is an external device attachable to the battery housing (3).

A rotary control valve and a sieve bed module assembly for use in pressure swing adsorption processes to make enriched oxygen product gas for therapy in patients is disclosed. The valve includes a stepping motor with a single shaft extending between ends. At ends of the valve, an air side valve function and oxygen side valve function are provided. Each end includes a stationary plate (stator) with ports, and a disc (rotor) that rotates with the shaft, opening and closing ports to achieve the desired valve function. The valve is integrated into the assembly between two sieve beds and a product storage tank is directly coupled to the oxygen side. Placement of the motor, shaft, and movable parts in the valve and mounting of the beds, valve, and tank in the assembly, result in more compact designs. The motor can be programmed to obtain multiple, different PSA processes and flexibility.
