  • Publication number: 20250214032
    Abstract: An air drying unit for compressed air systems includes a precooler/reheater, a main cooler, and a moisture separator. Incoming air is cooled to cause moisture within the compressed air to condense, and the condensate separated to dry the compressed air. The air drying unit includes an integrated intake filtration and outtake filtration sections with horizontally oriented filter elements that filter particulates and oil from incoming and outgoing compressed air.

  • Publication number: 20250153082
    Abstract: A filter for compressed air systems is provided. The filter includes a filter housing with a filter therein between an air inlet and an air outlet. Compressed air flowing between the air inlet and the air outlet passes through the filter housing and the filter element. A base is removably fastened to the filter housing which may be separated from the filter housing to allow the filter element to be removed and replaced.

  • Patent number: 12290782
    Abstract: Compressed air dryer systems are described. In an aspect, a system includes, but is not limited to, a plurality of dryer modules and a controller operable to regulate a run-time of each of the plurality of dryer modules. Each dryer module is configured to direct a portion of cooling medium past a stream of compressed air. Each dryer module includes a temperature sensor in thermal communication with the portion of cooling medium, and a chiller configured to reduce a temperature of the portion of cooling medium based on the sensed temperature and a temperature set-point. The controller communicatively is coupled with the plurality of dryer modules and operable to monitor a plurality of run-times. Each run-time is associated with a corresponding dryer module. The controller is further operable to direct operation of each dryer module based on its run-time by modifying the temperature set-point of the dryer module.

Incoming air is cooled to cause moisture within the compressed air to condense, which is then separated to dry the compressed air. The precooler/reheater, main cooler and moisture separator are designed as an integral unit that does not require pipes to connect the components together. Instead, compressed air flows through the sealed unit through passages therein between the precooler/reheater, main cooler and moisture separator.

  • Publication number: 20210095883
    Abstract: A compressed air drying system is provided for removing moisture from compressed air. The drying system is a modular system with multiple drying units arranged parallel to each other. The drying units cool the compressed air and remove moisture from the compressed air. In order to limit the number of drying units used during low demand periods, a separate air valve is included for each drying unit to control the flow of compressed air through the respective drying units.
