Publication number: 20260155707Abstract: The present invention is directed to a cooling tower comprising a cooling tower structure comprising fill material supported by the cooling tower structure and configured to receive heated process fluid and a motor mounted to the cooling tower structure. The motor comprises a casing and a rotatable shaft and is sealed to prevent fluids, moisture, foreign particles and contaminants from entering the casing. A fan is connected to the rotatable shaft of the motor. Rotation of the rotatable shaft rotates the fan thereby inducing an upward moving mass flow of cool air through the fill material. A basin is attached to the cooling tower structure for collecting cooled fluid. A fluid distribution system distributes the cooled fluid in the basin.Type: ApplicationFiled: January 25, 2026Publication date: June 4, 2026Applicant: Prime Datum Development Company, LLCInventors: Patrick M. Rollins, George Lucas
