Publication number: 20230142828Abstract: Device for adsorbing a gas from a gas mixture to be treated, having an inlet for gas to be treated and an outlet for treated gas, including at least two vessels filled with a regenerable adsorbent and an adjustable valve system connecting the inlet and outlet to the vessels, whereby the adjustable valve system is such that at least one vessel will treat compressed gas while the other vessel is regenerated, whereby by adjusting the valve system the vessels each in turn treat compressed gas sequentially, and the adjustable valve system is assembled in a single valve block.Type: ApplicationFiled: March 29, 2021Publication date: May 11, 2023Applicant: ATLAS COPCO AIRPOWER, NAAMLOZE VENNOOTSCHAPInventor: Wouter Denis Ann VAN DIJCK

Patent number: 9574828Abstract: Heat exchanger for exchanging heat between at least two fluids which are guided through chambers of the heat exchanger (1), wherein at least one guiding profile (11) is provided in the chambers (19,20), and the guiding profile (11) is an extruded tubular profile (12) which includes two parallel walls (13) which are connected to one another by means of two sidewalls (14). One or several dividing walls (15) extend in the extrusion direction of the tubular profile (12). One or several passages (17) are provided in the dividing walls (15) and/or in the sidewalls (14) for guiding a fluid.Type: GrantFiled: March 26, 2010Date of Patent: February 21, 2017Assignee: ATLAS COPCO AIRPOWER NAAMLOZE VENNOOTSCHAPInventors: Wouter Denis Ann Van Dijck, Patrick Piet A Dresen, Tom André J Potters

Patent number: 9283517Abstract: Method for cool drying gas containing water vapor, where a gas is led through a secondary part of a heat exchanger, whose primary part is an evaporator of a cooling circuit. The temperature or the dew point is measured in the environment of the place where, when cool drying, the temperature of the gas to be dried is the lowest. The above-mentioned method also has the step of switching off the cooling circuit when the decrease of the lowest measured gas temperature (LAT) or the dew point during a predetermined period of time amounts to less than a preset value (y).Type: GrantFiled: October 25, 2007Date of Patent: March 15, 2016Assignee: ATLAS COPCO AIRPOWER, NAAMLOZE VENNOOTSCHAPInventors: Wouter Denis Ann Van Dijck, Frederic Daniël Rita Van Nederkassel

Patent number: 9216378Abstract: Method for cool drying gas, in particular air, whereby this gas is guided through the secondary part of a heat exchanger (2) whose primary part is the vaporizer (3) of a cooling circuit (4), which consists in measuring the ambient temperature (Tamb), as well as the lowest gas temperature (LAT) or the dew point, and to switch the cooling circuit (4) on and off on the basis of these measurements in order to always maintain the lowest gas temperature (LAT) or the dew point between a pre-determined minimum and maximum threshold value, and whereby pre-determined threshold values are calculated on the basis of an algorithm which is a function of the measured ambient temperature (Tamb).Type: GrantFiled: April 28, 2006Date of Patent: December 22, 2015Assignee: ATLAS COPCO AIRPOWER, NAAMLOZE VENNOOTSCHAPInventors: Monica Dalla Valle, Wouter Denis Ann Van Dijck

Patent number: 9021818Abstract: Device for cool drying comprising a heat exchanger (2) whose primary part is the vaporizer (3) of a cooling circuit (4) which also includes a compressor (6) driven by a motor (5), a control device (16) for this motor (5) and measuring device (17) for the lowest air temperature (LAT), measuring device (18) for the ambient temperature (Tamb) and a flow meter (19), whereby this control device (16) can be at least switched in a first user mode in which the cooling circuit (4) is only activated when the gas flow exceeds a preset value and a second user mode in which the lowest air temperature (LAT) is maintained within a certain range by controlling the cooling circuit (4).Type: GrantFiled: June 1, 2006Date of Patent: May 5, 2015Assignee: Atlas Copco Airpower, Naamloze VennootschapInventors: Monica Dalla Valle, Wouter Denis Ann Van Dijck
