The BUNN BXWD Velocity Brew High Altitude Classic 10-Cup Home Brewer in White is specifically designed for use in high altitude areas, which includes a specially engineered thermostat for use above 4,000 feet and above. 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 the optimal brewing temperature required to extract the maximum flavor from coffee. The brewer uses 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 three minutes, less than half the time of most regular coffee makers.
