  • Adsorption-type air drying system with blower non-purge operation using compressed heat
    Patent number: 9511321
    Abstract: The present invention relates to an adsorption-type air drying system, of which the object is to simplify the flow paths of the system, reduce the number of the components such as a valve intricately controlled according to the state of operation, and decrease the cost for constructing the system. Furthermore, the object of the present invention is to provide an adsorption-type air drying system which may be used under various pressure conditions, and smoothly operated regardless of the pressure change of the system by way of a structure compensating for the pressure loss generated during non-purge operation.
