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

Patent number: 9956521Abstract: A multi-tower blower purge dryer system for use with a compressed air stream provided from a compressor is disclosed. In one form the system includes two dryers that can be alternated to dry the compressed air stream. The tower used to dry the compressed air stream can be referred to as the drying tower, and the tower being regenerated can be referred to as the regenerated tower. A number of valves and passages are used to connect the towers to one another and/or to an intake passage from the compressor. A blower purge heater is provided to regenerate the dryers. After a regeneration step in which a tower may be relatively warm, the valves can be actuated to place the warm regenerated tower in fluid communication with the intake passage from the compressor, which can then provide air to the drying tower. In this manner the regenerated tower is cooled.Type: GrantFiled: March 30, 2016Date of Patent: May 1, 2018Assignee: Ingersoll-Rand CompanyInventors: Henry Y. Mark, Janez Jakop

Patent number: 9259682Abstract: A gas compressing system includes a compressor that provides a flow of compressed gas, a first desiccant tower, and a second desiccant tower separate from the first tower. The system also includes a first separator, a second separator separate from the first separator, an outlet, a first set and second set of no more than three valves each movable between an open position and a closed position. The flow flows along a flow path from the compressor to the first tower, to the first separator, to the second tower and out the outlet when the first set of valves is open and the second set of valves is closed. The flow of compressed gas flows from the compressor to the second tower, to the second separator, to the first tower and out the outlet when the first set of valves is closed and the second set of valves is opened.Type: GrantFiled: June 4, 2014Date of Patent: February 16, 2016Assignee: Ingersoll-Rand CompanyInventors: Charles John Bergh, Henry Y Mark

Patent number: 5595238Abstract: Rotatably supported, regenerative fluid treatment wheel assemblies include a wheel with circumferential rim and track, a housing in which the wheel is disposed and a plurality of rollers disposed within the housing in rolling engagement with the track to locate a wheel axially and radially within the housing. Seal flanges are provided projecting radially outwardly from the rim and are opposed by flexible seals which are clip mounted to walls of the housing surrounding openings through those walls which are aligned with the wheel. At least one wheel is preferably spring loaded so to compensate for any eccentricity in the wheel. The wheel is belt driven. A subassembly, including a mounting plate, flange-mounted motor, drive pulley and spring loaded idler pulley is provided for easy installation and removal. Wear strips appropriate for contact with either the seal flanges or face of the wheel core are applied to the flexible seals by pressure sensitive adhesive.Type: GrantFiled: September 16, 1994Date of Patent: January 21, 1997Assignee: Engelhard/ICCInventors: Henry Y.
