    Producing Oxygen from Compressed Air

    Mentis MS-PSA-Series Oxygen Generators produce from 10 to 100 Nm3/h of oxygen per hour at up to 99% oxygen concentration.

    When electricity and a source of compressed air is supplied, these dependable machines can provide oxygen for any application.

    • Produces oxygen from an independent compressed air source
    • Microprocessor controlled
    • Low operating cost
    • Automatic and unattended operation
    • Easy to install and maintain
    • Touchscreen control panel with integrated oxygen concentration monitor

    How PSA Works? 

    • Air contains 21% Oxygen, 78% Nitrogen, 0.9% Argon and 0.1% other trace gases. Mentis S-PSA Oxygen Generation Systems separate this oxygen from Compressed Air through a unique process called Pressure Swing Adsorption. (PSA).
    • The Pressure Swing Adsorption process for the generation of enriched oxygen gas from ambient air utilises the ability of a synthetic Zeolite Molecular Sieve to absorb mainly nitrogen. While nitrogen concentrates in the pore system of the Zeolite, Oxygen Gas is produced as a product.

    Mentis S-PSA "Management of Athmospheric Contamination Movement"

    • This is the most distinctive feature that distinguishes our technology from other PSA oxygen and nitrogen generating technologies.
    • Compressed air is a source of many contaminations while compressing. We are sure that; Pressurized air coming from compressors is not suitable for separation process yet. That’s why, pressurized air must be cleaned, separated until free from contaminants completely.
    • S-PSA technology is composed of a two stage PSA cycles.  First stage cycle is purifier the compressed air from all contaminations and unwanted gaseous. Second stage cycle is just separating to product gas from other gaseous.
    • These process developed by Mentis for long life and high purity air separation technique.

    Typical Installation

    Siemens SIMATIC HMI KTP600 

    Basic color 6 inch Basic Panel with TFT display and combined key and touch operation

    The KTP600 Basic color offers a 5.7 inch Touch Display and additionally 6 tactile keys. It is available in two versions: KTP600 Basic color DP for MPI/PROFIBUS DP connections and KTP600 Basic color PN with an Ethernet interface. 

    Area of application

    Panel for HMI tasks of limited complexity yet enhanced requirements in visualization for the use in PROFIBUS or PROFINET networks according to the chosen variant; especially in combination with SIMATIC S7-1200 controllers but also with other controllers.


    • HMI- Basic functionality for PROFIBUS or PROFINET environment
    • Low price alternative to panels of series 170
    • Can be used worldwide with 32 configurable languages (of which 5 are online-switchable)


    Optionally Product Design

    Oxygen / Nitrogen
    • In Mobile Container

    Any nitrogen or oxygen generators can be installed in a special container with independent power supply (diesel or gas generator) and are mounted on the chassis for any motor vehicle or trailer.

    The container is designed for mounting on a chassis.  There is the following systems in the container:

    • Diesel power generator
    • Air conditioning system
    • Heating and ventilation system
    • Fire alarm system
    • Power cabinet
    • Lighting
    • Security alarm
    • In Container

    Our oxygen and nitrogen generators can be placed into the 20-foot sea container designed for  any climatic zone, as for a tropical climate and as well as for the far north.

    There is the following systems in a container,

    • Air conditioning system
    • Heating and ventilation system
    • Fire alarm system
    • Power cabinet
    • Light
    • Security alarm
    • Filling Station

    You can add a high pressure system filling station to your oxygen generator solution. This makes it possible to fill your own cylinders with a pressure of up to 200 bar.

    Please note that you also need a high pressure compressor to fill cylinders or bottles.

    It is possible to make a system for filling bottles and for feeding a central oxygen / nitrogen system at the same time.
