Vertex Water Products of Montclair, Calif., introduces an expanded line of point-of-use pure water coolers. Available in 2-temperature (hot and cold) or 3-temperature (hot, room, and cold), the Vertex PureWaterCooler™ is rugged, handsomely designed and easy to clean. The reverse osmosis option makes clean water from city water, eliminating the need for storing and handling 5-gallon bottles. The units feature a tough ABS plastic and steel cabinet, no-drip faucets and easy access to filters through a removable front panel. Countertop models are also available and a UV option can be added to any cooler.
