Product Description
The Friga-Bohn 3C-E 4466 R Cubic Unit Cooler is an ultra heavy-duty industrial evaporator designed for very large commercial refrigeration systems and cold storage facilities. It is equipped with 4 × 450 mm axial fans operating at 1370 rpm, delivering approximately 16,230 m³/h airflow with an air throw of up to 39 meters, ensuring maximum air coverage across very large spaces.
The unit features a high-efficiency heat exchanger constructed with internally grooved copper tubes and aluminium fins (4 mm spacing), providing superior heat transfer performance. With an extremely large heat exchange surface of 110.6 m², it delivers the highest cooling capacity in the 3C-E series.
Designed with large industrial dimensions (2811 × 593 × 635 mm) and a net weight of 113 kg, the unit is ideal for heavy-duty industrial refrigeration installations.
Operating on 230–400V / 3Ph / 50Hz, the unit delivers a cooling capacity of approximately 31.17 kW under standard conditions (R22, 0°C room temperature) .
