Specifically designed for use in high-altitude areas, this special version of the BUNN BX-B offers BUNN brewing perfection with the Classic, stainless steel accented design that customers have loved for years. Patterned after BUNN's commercial & restaurant brewing systems, this home brewer puts high quality materials and classic brewing technology into one great package. The stainless-steel tank holds the brew water at approximately 200?F, the temperature required to extract the maximum flavor from coffee. The patented BUNN brewing system showers the water over the ground coffee using a specially designed sprayhead to create optimum turbulence in the funnel for just the right amount of time. As a result, BUNN home brewers produce 10 cups of perfect coffee in about 3 minutes --- less than half the time of most regular coffee makers. This combination of "time, temperature & turbulence" is the hallmark of BUNN's home brewing system --- and something unavailable in any other home brewer.
