A dehumidifying system uses a membrane cartridge to filter water vapor from air or other gas introduced into the membrane cartridge via a main pump or compressor. Dehumidified gas from the membrane cartridge is then delivered into a system which requires dry gas. The dehumidifying system further includes valve arrangements or additional compressors which provide gas flow through the membrane cartridge when the main compressor is inactive. Therefore, the membrane cartridge receives a substantially continuous flow of gas which maintains the optimal efficiency of the membrane cartridge. In addition to the arrangements which provide this continuous gas flow, a heating coil wrapped around the membrane cartridge raises the temperature of the fiber membranes within the cartridge. The heated fiber membranes are less susceptible to retain moisture which decreases the efficiency of the membrane cartridge.

A method of dehumidifying gas comprising the steps of routing gas through a membrane cartridge for a first time period, said membrane cartridge having membranes which filter water vapor contained in said gas through said membranes, said membrane cartridge having a first outlet for ejecting dehumidified gas from said cartridge and a second outlet for ejecting water vapor from said cartridge; directing said dehumidified gas from said first outlet of said membrane cartridge into a dry gas system; and passing gas back into said membrane cartridge through said first outlet for a second time period after said first time period. A gas supply system for furnishing pressurized and dehumidified gas to a selected space, said system comprising a primary gas source for supplying pressurized gas, a membrane cartridge having an inlet for receiving said pressurized gas from said primary gas source and an outlet for supplying dehumidified, pressurized gas to said selected space, said cartridge having membranes which filter water vapor contained in said gas through said membranes, and a second outlet for ejecting water vapor from said cartridge, control means for repetitively energizing and de-energizing said primary gas source so that said pressurized gas is supplied intermittently to said selected space, and a secondary gas source for supplying gas to said membrane cartridge when said primary gas source is de-energized so as to maintain the effectiveness of said membranes during the periods of de-energization of said primary gas source.
