This 36-cup, 3-warmer pour-over coffee brewer is a workhorse. It offers easy operation and set-up with no installation required. And it's fast; brews in 3 1/2 minutes. Then the warmers keep 12-cup carafes at the proper serving temperature. Plus, this brewer is energy efficient and half the cost of traditional tank brewers to operate. The pour-over system eliminates the need for a water reservoir, so fresh water is used to brew each pot, and in case of a main water line break or shut-off, the pour-over option still lets everyone have their cup of coffee. With an easy-to-clean stainless steel cabinet and auto water heater shut-off after brew cycle. The unit includes a master power cut-off switch and brew alert light and has a three-prong grounded plug and separate lighted on/off switches. UL Listed and CSA Commercial Code Approved. Carafes are sold separately.
