The Turbo-Air M3F47-4-N M3 freezer is a top-mount reach-in freezer designed for commercial kitchens. It has a total capacity of 42.1 cu. ft. and dimensions of 51 3/4" wide x 30 3/4" deep x 78" tall. The freezer features six heavy-duty wire shelves, with the option to add more, and energy-efficient LED interior lighting. The exterior of the freezer is constructed with stainless steel front, sides, doors, and interior floor, while the interior is made of aluminum. The four half-hinged doors have recessed handles, locks, and magnetic door gaskets that can be easily removed. The doors use pressure release for easy opening and emit a beep each time they are opened. If a door remains open for an extended period, an alarm will sound. The temperature of the freezer can be set from -10°F to 0°F using the temperature control and monitoring system accessible through the LED display. The system is self-diagnostic and notifies users of any potential issues. The freezer also has a smart fuzzy defrost feature that defrosts only when necessary and a Turbo Freeze option to quickly cool down the interior when new items are added. The Turbo-Air M3F47-4-N has a self-cleaning condenser system with a rotating brush that cleans the condenser two to three times per day. It uses Turbo-Air's energy-saving hot gas condensate system and foamed-in-place polyurethane insulation for increased energy efficiency. The freezer uses the environmentally-friendly refrigerant R290, which has a low ozone depletion potential and global warming potential. It is equipped with 4" swivel casters with locks on the front set, and optional stainless steel legs are available. Additional half-door bun tray racks can also be added for an extra charge.
