Product Description
The Friga-Bohn MHE 770 E Ceiling Unit Cooler is a high-capacity evaporator designed for low-temperature refrigeration applications (-18°C) such as large freezer rooms and cold storage facilities. Its ceiling-mounted, low-profile design ensures efficient space utilization while delivering powerful cooling performance.
The unit is equipped with 4 × 300 mm axial fans operating at 1500 rpm, delivering approximately 4160 m³/h airflow with an air throw of up to 16 meters, ensuring uniform air distribution across medium to large cold rooms.
It features a high-efficiency heat exchanger constructed with internally grooved copper tubes and aluminium fins (4.23 mm spacing), ensuring reliable heat transfer. With a large heat exchange surface of 26.15 m², it provides significantly higher performance compared to smaller ceiling models.
Designed with extended dimensions (2499 × 607 × 260 mm) and a net weight of 57 kg, the unit is suitable for larger installations while maintaining a compact ceiling format.
Operating on 230V / 1Ph / 50Hz, the unit delivers a cooling capacity of approximately 5.22 kW under standard conditions (R404A, -18°C room temperature) .
