Never worry about replacing water bottles

As the best plumbed-in water cooler on the market, it never needs to be connected to an external water bottle. That way, you can enjoy a refreshing glass of warm or cool water without replacing any bottles.

Thanks to its built-in water filter (an optional extra), the dispenser allows your whole building to access healthy, refreshing water from your main supply. It minimises the risk of bacteria and germs spreading within the building.

Save time that would otherwise be spent replacing water bottles, as well as save money.


How do filtered water coolers work?

Filtered water coolers use a refrigerant to cool the water. This refrigerant is compressed and becomes hot before it is passed through a condenser, which cools it back down. The refrigerant's temperature drops further once it’s passed through an expansion valve.

How often should I change the water filter in a commercial water cooler?

Water filters used in commercial water coolers must be replaced every four to six months. Frequently replacing the water bubbler’s filter prevents any build-up of debris, bacteria and pesticides and keeps the water fresh and sanitised.

How often should commercial water coolers be cleaned?

It’s a good idea to clean and disinfect your commercial water cooler each time you replace the water bottle to prevent any germs or bacteria from entering the water. However, using a bleach solution, a deep and sanitising clean is recommended every three to six months.

Can mould grow in commercial water coolers?

Yes, if not properly maintained and regularly cleaned, the moist environment can cause mould and mildew in a filtered water cooler. If you notice a mould or mildew build-up in your water cooler or the water has developed an odd taste, you will need to deeply clean the cooler or replace the system altogether.
