All stainless steel exterior with nickel plated trim. A showpiece in any kitchen or office. High end look like professional espresso machines. * Self cleans several times a day using reactive oxygen technology. The unstable oxygen rips bacteria apart and keeps the cooler clean from biofilm, and murky off tastes. * Glacial Chill technology uses a ring of ice to keep water at a steady temperature just above freezing, making a refreshingly chilly glass of water. Produces 1.6 gallons of icy cold water per hour. * HotBoost technology injects preheated water into the hot tank, maintaining a very high average temperature. Produces 1.4 gallons of piping hot water per hour. * Professional Grade compressor technology turns on about 30 times less than the average commercial grade cooler; which often starts failing after a year or two of use.
