Product Description
The Friga-Bohn 3C-E 4366 E 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 12,170 m³/h airflow with an air throw of up to 36 meters, ensuring powerful air distribution across large industrial 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 extra-large heat exchange surface of 82.9 m², it delivers significantly higher efficiency and cooling capacity compared to C models.
Designed with industrial dimensions (2211 × 593 × 635 mm) and a net weight of 87 kg, the unit is ideal for heavy-duty cold storage and industrial refrigeration systems.
Operating on 230–400V / 3Ph / 50Hz, the unit delivers a cooling capacity of approximately 19.15 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.
