Product Description
The Friga-Bohn 3C-E 3343 C Cubic Unit Cooler is a high-capacity evaporator designed for commercial cold rooms and low-temperature refrigeration applications. It is equipped with 3 × 300 mm axial fans operating at 1350 rpm, delivering approximately 3770 m³/h airflow with an air throw of up to 21 meters, ensuring powerful and uniform air distribution for larger cold rooms.
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 environments by reducing frost accumulation. With a heat exchange surface of 12.7 m², it provides reliable and consistent cooling performance.
Designed with extended dimensions (1567 × 480 × 428 mm) and a net weight of 31 kg, the unit is suitable for medium to large cold room installations requiring higher airflow.
Operating on 230V / 1Ph / 50–60Hz, the unit delivers a cooling capacity of approximately 3.85 kW under standard conditions (R404A, -18°C room temperature). It includes a built-in electric defrost system (3440 W) for efficient frost removal and reliable operation.
