Publication number: 20230321594Abstract: A compressed air drying system is provided for removing moisture from compressed air. The dryer operates in two modes in response to the demand for compressed air. In a first mode of operation, a refrigeration compressor runs continuously and the speed of a condenser fan is varied to maintain a constant cooling temperature. In a second mode of operation, the refrigeration compressor runs intermittently between on and off periods. As result, the cooling temperature fluctuates during the second mode of operation.Type: ApplicationFiled: May 30, 2023Publication date: October 12, 2023Inventors: Stefano Vezil, Paolo Depiero, Giovanni Battista Capellari

Publication number: 20230264144Abstract: An air drying unit for compressed air systems is provided. The air drying unit has a precooler/reheater, a main cooler and a moisture separator. 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.Type: ApplicationFiled: May 1, 2023Publication date: August 24, 2023Inventors: Henry Y. Mark, Scott A. Johnson, Stefano Vezil

Publication number: 20210095883Abstract: 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.Type: ApplicationFiled: September 30, 2019Publication date: April 1, 2021Inventors: Henry Y.

Patent number: 10724750Abstract: Dryer for compressed air including at least one cooling unit (28), able to cool a refrigerant fluid circulating in at least one drying unit (22), provided with an air inlet (11) and an air outlet (13) and also comprising at least one circuit (18) inside which air to be treated circulates from said air inlet (11) to said air outlet (13). The dryer for compressed air comprises, along the circuit (18), at least one cooling apparatus (12), configured to cool the compressed air to positive temperatures, a few degrees above zero and near to freezing temperature, and at least one freezing apparatus (14), disposed downstream of the cooling apparatus (12) and configured to cool the compressed air to abundantly negative values.Type: GrantFiled: November 28, 2016Date of Patent: July 28, 2020Assignee: Officine Meccaniche Industriali S.R.L.

Patent number: 10179307Abstract: An air compressor system is disclosed that includes a housing sized to enclose an air compressor pump as well as a dryer structured to remove moisture from air that is compressed by the compressor pump. The air compressor pump may be intermittently placed into operation, but the dryer itself is structured in one form to continuously maintain a heat exchanger in a desired temperature range in anticipation of operation of the air compressor pump. The heat exchanger of the dryer can include sufficient thermal mass such that a refrigerant pump of the dryer need not be operated continuously in anticipation of operation of the air compressor pump. While a cooling air flow can be created by operation of the air compressor pump, when the air compressor pump is not operated a cooling fan can be used provide cooling to the heat generating components of the dryer.Type: GrantFiled: April 28, 2017Date of Patent: January 15, 2019Assignee: Ingersoll-Rand CompanyInventors: Paolo De Piero, Stefano Vezil, Charles John Bergh
