The Kolumba BTB is an island for impulse sales with a low, straight front glass, so shoppers serve themselves and the whole assortment stays in view. This is the remote version: no condensing unit is supplied, the island is connected to an external condensing unit or remote system, and the refrigerant is chosen to suit that system.
Fan-assisted cooling runs on energy-efficient fans, and the evaporator is fitted with a heater. The display surface, the mould and the evaporator cover are stainless steel, finished with a PVC bumper. The manufacturer credits the cabinet design with lower power consumption, the display area is large enough for a full range, and with a connecting kit islands can be joined in a line.
Two modules are listed: 1.875 at 3000 mm with 768 litres of useful capacity, and 2.5 at 2500 mm with 927 litres, both with 24 mm side panels. The working range is 0…+4 °C in climate class 3 (+25 °C, 60% RH), on a 230 V / 50 Hz electrical connection.
