Abstract: An air compressor system useful for supplying a stream of compressed air for an end user is disclosed which includes a refrigerated dryer useful to remove moisture and harvest it from the compressed air. The refrigerated dryer includes an evaporator and a condenser, where the evaporator is useful to produce the moisture from the compressed air. The air compressor system includes an expansion tank which collects the harvested moisture from the evaporator and a supply line from a utility water supply, both of which can be used to provide liquid to a condenser of the dryer. A valve is used to bring together either or both of the condensate from the expansion tank and water from the utility water supply. The valve includes an outlet that provides liquid to a condenser of the dryer.

Abstract: A compressor system is disclosed having a refrigerated dryer useful to remove moisture from a wet compressed flow stream produced by a compressor. The refrigerated dryer can include a condenser having a refrigerant fluid conduit and a number of external cooling fins which assist in cooling the refrigerant fluid upon passage of a cooling flow stream past the external cooling fins. The compressor system can include an offtake passage to extract a portion of the wet compressed gas. The extracted portion of compressed gas can be blown in a direction transverse to (e.g. opposite) the direction of cooling air provided by the fan. In one form the fan can be deactivated when the extracted compressed air is flowed past the cooling fins. The compressor system can include a manual operation, operation dictated by a timer, or operations based upon sensed/estimated/etc pressures or temperatures of the compressor system.

Abstract: An air compressor system useful for supplying a stream of compressed air for an end user is disclosed which includes a refrigerated dryer useful to remove moisture and harvest it from the compressed air. The refrigerated dryer includes an evaporator and a condenser, where the evaporator is useful to produce the moisture from the compressed air. The air compressor system includes an expansion tank which collects the harvested moisture from the evaporator. The expansion tank can include a low liquid level sensor useful to determine a low liquid level of condensate in the expansion tank. The low liquid level sensor can produce a signal indicating a low level of condensate which can be used to shut off a pump that pulls water from the expansion tank and provides it to the condenser of the refrigerated dryer.

Abstract: An air compressor system having a refrigerated dryer and a form of a filter is used between a compressor of the air compressor system and the refrigerated dryer. The filter can include a conical shape such as frustoconical, and includes an outer retainer having a plurality of openings and an inner mesh filter. The retainer and mesh filter can be made out of metal. An end cap and a flange can close off both ends of the conical shape, and a handle can extend from a flange to aid in ease of handling. The components extending between the ends (i.e. between the end cap and flange) may only include the retainer and the mesh filter.

The refrigerated dryer includes an evaporator and a condenser, where the evaporator is useful to produce the moisture from the compressed air. The air compressor system includes an expansion tank which collects the harvested moisture from the evaporator. The expansion tank can provide liquid to a pump that conveys the liquid to a condenser of the dryer. The refrigerated dryer includes a temperature sensor that detects a temperature of refrigerated fluid associated with the condenser and regulates the pump to supply liquid to the condenser to assist in heat rejection.

The refrigerated dryer includes an evaporator and a condenser, where the evaporator is useful to produce the moisture from the compressed air. The air compressor system includes an expansion tank which collects the harvested moisture from the evaporator. The expansion tank can include a low liquid level sensor and a high liquid level sensor useful to determine level of condensate in the expansion tank. The low liquid level sensor can produce a useful to permit ingress of water from a utility water supply into the expansion tank, and the high liquid level sensor can produce a signal useful to venting excess liquid from the tank.
