he Keurig K-3550 is a commercial-grade single-serve brewer designed for high-traffic break rooms, large offices, hospitality settings, and other business environments. It features direct-water-line plumbing for continuous back-to-back brewing, selectable cup sizes (4, 6, 8, 10, 12 oz), a “STRONG” brew option for a bolder cup, and a dedicated “Brew Over Ice” button that allows you to brew hot coffee over ice for iced beverages. The intuitive high-resolution touchscreen lets users select drinks, access technician/manager menus, and manage settings like energy-saving mode and sleep mode. The brewer also automatically ejects used K-Cup® pods into a built-in bin, helping with neatness and speed. Its internal design supports a drainable tank for easy relocation, and two hot-water tanks for unlimited sequential brewing. It’s built for continuous heavy use and features commercial certifications (NSF, UL).
