Abstract: A water chiller includes a cooling tank and a cooling device positioned at an upper portion of the cooling tank. The cooling device includes a cooling probe positioned within the cooling tank at an upper region thereof and being operable to cool the water at the upper region of the cooling tank. The cooled water increases in density and descends toward the bottom or lower region of the cooling tank, while warmer water positioned in the lower region rises upwards toward the cooling probe, where it is cooled by the cooling probe. The water cooler thus continually cools and mixes the water within the cooling tank to maintain the water at a cool temperature. The cool water at the lower region of the tank is discharged from the cooling tank at an outlet positioned at or near the bottom of the cooling tank.

Abstract: A method of manufacturing and remanufacturing a water treatment device having a media bed includes assembling a housing from a length of open pipe and a pair of end caps. One end cap is secured to each open end of the pipe. At lease two openings are formed at opposite ends of the housing. The housing is charged with media by passing the media through the openings in the housing. A pair of screens are provided in the housing outwardly of the media, and a pair of fittings are provided in the openings outwardly of the screens. The end caps may be permanently secured to the pipe, such as by an adhesive or other known techniques, prior to charging the housing with media. The water treatment device may be charged with media by forming a slurry, made up of the media and a liquid, and passing the slurry through the opening in the pipe. Liquid may then be drawn out of the housing through one of the fittings. At least one of the end caps may include a wall portion which overlaps a portion of the pipe.
