Water coolers are essential for any establishment and even for the home. These appliances have refrigeration and heating methods that make them great for freeing up space in the fridge or eliminating the need for keeping a water kettle in the kitchen. Many designs use vapour compression refrigeration or thermoelectric cooling, while hot water may be dispensed by going through a heating element and stored in a hot tank.Self-Cleaning Water Coolers
Many commercial grade water coolers have self-cleaning functions that use UV light along the distribution lines to destroy bacteria. These types have larger upfront costs but help save maintenance costs due to their automatic cleaning functions.Bottleless Water Coolers
Connected directly to your building’s water line, this type of water cooler depends on your local water supply. Their refrigeration units cool the incoming water and dispose of unused water via a connection to waste disposal lines. Typical examples are drinking fountains. Since they are connected to the water line, these systems usually depend on water filters to keep the water clean and safe to drink.Bottled Water Coolers
Bottled water coolers are your typical freestanding coolers. The bottles are placed upside down on the dispenser to feed water into the cooling and heating tanks via gravity. Standard designs use a secondary capping system, which is pushed into the bottle when you tip it into the cooler, thereby preventing spillage when you replace the bottle. Many unbranded water coolers use this design and are also quite reliable.Bottom-Load Water Dispensers
These dispensers feature a clean, modern design that hides the bottle within a door at the base of the cooler. A pump system draws water up from the bottle and into the cooling and heating chambers. Bottom-load water dispensers are more expensive than your typical cooler but may come with useful features like water temperature indicators and make replacing the bottles nearly effortless compared to top-fed coolers.
