Patent number: 11131507Abstract: A hybrid heat exchanger apparatus having a heat exchanger device with a hot fluid flowing therethrough includes a cooling water distribution system and an air flow mechanism for causing ambient air to flow across the heat exchanger device. The cooling water distribution system distributes evaporative cooling water onto the heat exchanger device to wet only a portion of the heat exchanger device while allowing a remaining portion of the heat exchanger device to be dry. The air flow mechanism causes ambient air to flow across the heat exchanger device to generate hot humid air from the ambient air flowing across the wet portion of the heat exchanger device and hot dry air from the ambient air flowing across the remaining dry portion of the heat exchanger device. Methods are also described.Type: GrantFiled: February 24, 2015Date of Patent: September 28, 2021Assignee: Evapco, Inc.Inventors: Thomas W. Bugler, III, Davey J. Vadder

Publication number: 20180231264Abstract: A once-through dry adiabatic cooler having a water distribution system, a waste water sensor, and a controller, where the amount of waste water, if any, is detected, and the amount of water distributed to an air flow path adjacent to the coils of said cooler is adjusted so that the amount of water detected is as close to zero as possible, or, in the case of the use of adiabatic pads that require flushing, only the amount of water necessary to flush salt and other minerals from said pads.Type: ApplicationFiled: February 8, 2018Publication date: August 16, 2018Inventors: Davey J.

Patent number: 10030663Abstract: A method and apparatus for removing and replacing an integral-motor fan from below. A support assembly has support struts fixed to a mounting ring. Mounting ring is configured to be fixed to the fan head, holding the fan in place, and support struts are configured to rest on mounting bolts fixed to a fan shroud. To mount a fan in place from below, the fan is fixed to the mounting ring of the support assembly, and the support assembly and attached fan are lifted into the fan shroud. The support assembly is rotated until the struts align with the support bolts in the fan shroud. The support assembly is then lowered until the struts come to rest on the support bolts. A power cable with a length sufficient to lower the fan support assembly out of the fan shroud prior to disconnecting the power cable from the fan body.Type: GrantFiled: September 12, 2014Date of Patent: July 24, 2018Assignee: Evapco, Inc.Inventors: Davey J. Vadder, Jacob P. Myers

Patent number: 9091485Abstract: A hybrid heat exchanger apparatus includes a direct heat exchanger device and an indirect heat exchanger device and a method of operating the same encompasses conveying a hot fluid to be cooled from a hot fluid source through the indirect heat exchanger device to a cooling fluid distribution system. The hot fluid to be cooled is distributed from the cooling fluid distribution system onto the direct heat exchanger device. In a hybrid wet/dry mode, ambient air flows across both the indirect heat exchanger device and the direct heat exchanger device to generate hot humid air from the ambient air flowing across the direct heat exchanger device and hot dry air from the ambient air flowing across the indirect heat exchanger device.Type: GrantFiled: October 18, 2010Date of Patent: July 28, 2015Assignee: EVAPCO, INC.Inventors: Thomas W.

Publication number: 20100052703Abstract: An ice thickness probe includes a longitudinally-extending probe rod, an insulator casing and a sleeve. The probe rod is fabricated from an electrically-conductive material. The insulator casing is fabricated from an electrically-insulative material and is wrapped around, is in contact with and extends along the probe rod. The sleeve is fabricated from a stiff yet resilient material and is wrapped around, is in contact with and extends along the insulator casing. The insulator casing and the sleeve are concentrically disposed about the probe rod as viewed in cross-section. An ice thickness probe assembly includes a frame structure, a reference bar and at least one ice thickness probe. An ice thickness monitoring apparatus is used in a thermal storage coil having a tank containing water and a tube disposed in the water so that, when the thermal ice storage coil is energized, ice is produced and accumulates on the tube.Type: ApplicationFiled: August 26, 2008Publication date: March 4, 2010Applicant: EVAPCO, INC.Inventors: Davey J.
