Cooler combo units are Elkay’s most famous products. Those are indoor bottle filling stations mounted directly on the wall and that feature a bottle filler and either a single fountain or a double, bi-level drinking fountain. 

Bi-level cooler combos have fountains of different heights (a lower and a higher one) to help Schools and other facilities meet ADA compliance requirements. 

This product type boasts several different product lines covering different needs. Among the different features available, energy-efficient chillers, full sensor-activation and vandal-resistance are among the most popular ones. These models are also usually available filtered and filterless as well as chilled and non-chilled to better suit specific needs.
