Halsey Taylor's line of freeze-resistant drinking fountains has recently been expanded to include a variety of models with an ultra sanitary freeze-resistant valve system. Like their standard freeze-resistant models, these systems are designed for ground installation 18 inches below the frost line. In addition, the new sanitary system features a fully sealed assembly. Halsey Taylor's sanitary freeze-resistant offering includes pedestal models from the Endura II™ Tubular, Endura™ Steel and Sierra™ Stone families. Most models meet the requirements of ADA.
