It relies on membrane-separation technology to remove moisture from an air stream. This gives complete control over humidity removal by regulating the flow of air. Gas dryers are economical to operate and maintain as it consumes no energy and no moving parts are required. The only expense is the energy required to provide a stream of compressed feed air.
Removing moisture from compressed air is essential for virtually all applications. Air quality requirements and ambient conditions will help determine the type of dryer required. Few of the gas dryers are air dryers, compressed air dryers, refrigerated dryers, adsorption air dryer and dessicant air dryer.
