Product Description
The Friga-Bohn 3C-E 4366 C Cubic Unit Cooler is an ultra high-capacity industrial evaporator designed for large cold rooms and low-temperature refrigeration applications. It is equipped with 3 × 450 mm axial fans operating at 1370 rpm, delivering approximately 13,000 m³/h airflow with an air throw of up to 37 meters, ensuring powerful air distribution across very large spaces.
The unit features a high-efficiency heat exchanger constructed with internally grooved copper tubes and aluminium fins (6 mm spacing), making it ideal for low-temperature applications by minimizing frost buildup. With a large heat exchange surface of 57.4 m², it delivers excellent cooling performance for demanding environments.
Designed with large industrial dimensions (2211 × 593 × 635 mm) and a net weight of 82 kg, the unit is suitable for heavy-duty cold storage and industrial refrigeration systems.
Operating on 230–400V / 3Ph / 50Hz, the unit delivers a cooling capacity of approximately 17.45 kW under standard conditions (R404A, -18°C room temperature) .
It includes a high-capacity electric defrost system (9720 W) for efficient frost removal in low-temperature environments.
