The Billi Quadra is the ultimate drinking water appliance providing the convenience of an instant supply of refreshing filtered water, both boiling and chilled. These are the most compact commercial units available, and require absolutely no cupboard ventilation. Their unique ability to internally recycle waste heat ensures that the Billi Quadra remains the class leader in eco-friendliness, as well as resulting in lower running costs to the end user. This legendary efficiency has resulted in Billi Quadras being chosen for the CH2 building in Melbourne, the Worlds Greenest Multi-Storey Office Building, as well as winning Gold in the prestigious International EID Awards.
