    INDUSTRY APPLIACTION

    Advantages

    1. Uses liquid pumps to pressurize liquid oxygen, then converse LOX into GOX in the main heat exchanger.
    2. Has a higher outlet pressure at the booster end of the expander so it saves more energy.
    3. Has a secondary operating condition so the client has option of more fraction of LOX product.
