The invention provides a method and system for suppressing the dew point of a compressed gas to a minimum level below ambient temperature by controlling pressure, cooling and removing liquid water condensate from the compressed gas prior to storage in a receiver vessel and/or delivery to point of use. In one embodiment, the method has an air intake for accepting ambient air having any level of water vapour content, a compressor for compressing the air, a heat exchanger which cools the compressed air and sets the water vapour content of the air to a value determined by the pressure and the exit temperature of air in the heat exchanger, a liquid water separation device which removes condensed liquid water, a pressure control valve which ensures the maintenance of a minimum set pressure in the upstream system, an air receiver to act as a reservoir for the delivery of unsaturated compressed air and a main system regulation valve used to limit the maximum pressure of the compressed air delivered to the downstream system. In a preferred embodiment, the equipment and methodology forms a complete system that can be used for general compressed air applications as well as in specific compressed gas processes that have a dry gas requirement.
