The BA21S is a Tefcold two-door back-bar fridge with sliding glass doors for restaurants and cafés. The self-closing sliding doors are aluminium-framed and double-glazed with toughened glass, which saves energy and keeps the drinks on view. Behind each door are adjustable shelves, four chrome wire shelves in total, and more can be added.
A variable-speed compressor and ventilated cooling give a short pull-down time. Defrost and defrost-water evaporation are automatic; the thermostat is electronic, the thermometer digital and the lighting LED. The doors lock.
