Abstract: According to one aspect of the present disclosure, a control system and method of controlling a refrigerated dryer of a gas compressor system are disclosed. The control system, including a controller and a flow sensor, selectively operates in a power saving mode in which the controller shuts down a refrigerant compressor included in the dryer system when the flow sensor indicates that no compressed gas is flowing through the dryer. In a further aspect of the present disclosure, the control system uses input from a temperature sensor to determine whether to activate the compressor regardless of the flow of compressed gas through the dryer. Consequently, the control system enables the dryer to perform with aspects of both non-cyclic and cyclic dryers without the added cost and complexity of a conventional cyclic dryer.

Abstract: A drying system for compressed gas includes a fluid conduit, a cooler, and a precooler. The fluid conduit receives a flow of compressed gas to be cooled by the cooler and precooled by the precooler. The precooler has a gas-to-gas heat exchange section and a gas-to-liquid heat exchange section. A liquid-gas separator is coupled with the fluid conduit, and with a gas line and a liquid line. The gas line conveys gas to the gas-to-gas heat exchange section and the liquid line conveys liquid condensate to the gas-to-liquid heat exchange section.
