SUMMIT offers a versatile line of full-sized built-in beer dispensers designed for low maintenance storage in the style of your choice. This beer dispenser comes with everything you need except the kegs. It's a great option for refrigerating and serving kombucha or soda in addition to beer with a few easy upgrades. You will need to get the CO2 tank filled locally. A quick search for gas or welding suppliers in your local yellow pages will help you find a place to get the tank filled. A full CO2 tank should last about 5 to 6 full size kegs. The SBC635MBIFRTWIN is a full-sized beer dispenser that can store a half barrel keg or two 1/6 barrels to best accommodate all tastes. It is designed for both freestanding and built-in installation. The door includes a two-piece stainless steel frame designed to accept a slide-in custom panel, allowing you to create a seamless look with your surrounding decor (panel dimensions: 23-1/2" wide x 30-5/8" tall x 1/4" thick). A stainless steel handle completes the look. The surface includes a removable drip tray to collect spills and a chrome guard rail to help keep glasses and mugs in place. This unit is height adjustable from 33 1/2" to 34" to best fit your undercounter space. Please note that the door does not open in its own radius. When planning your cutout, if the unit is mounted against a wall or flush under cabinetry, you will need between 25 and 25 1/4" width for proper ventilation. Automatic defrost operation ensures minimum user maintenance inside the 5.7 cu.ft. interior. A digital thermostat makes it easy to manage the temperature at the touch of a button. The external digital display shows the temperature in Celsius or Fahrenheit to ensure your beer is stored exactly how you like it. The floor is reinforced with a steel cover for added durability when loading kegs. All SBC635MBI beer dispensers can fit one half barrel keg, two 1/6 barrel kegs, or a pony keg.
