Water coolers are devices that provide chilled and/or hot water for drinking purposes. They come in two main types: bottled water coolers, which use pre-filled water bottles, and point-of-use (POU) coolers, which connect directly to a water supply line. Chilled water is produced through refrigeration or thermoelectric cooling, while hot water is heated using a heating element or tank. Some models include filtration systems to improve water quality. Regular maintenance and cleaning are necessary for proper functioning and hygiene. When choosing a water cooler, consider capacity, performance, filtration, and compliance with health and safety standards.
