ECO Commercial Evaporators
DFE Dual Discharge Unit Coolers with Dual Speed Motors
The dual discharge DFE range has been specifically designed for applications in cold rooms with limited height for the
preservation of fresh or frozen products.
The models are equipped with dual velocity fan motors allowing to use the same unit for either normal ventilation or
reduced ventilation (for low noise level).
The entire range is equipped with high efficiency coils made from special profile aluminium fins and copper tube,
suitable for the new generation refrigerants.
For applications in rooms with higher temperatures (> +2 °C) 3,5 mm fin spacing, for medium and lower
temperatures (> -25 °C) we recommend 7,0 mm fin spacing with electric defrost.
The dual velocity fan motors employed have the following features:
diameter 315 mm external rotor single phase 230V/1/50-60 Hz with built-in electric capacitor and fibreglass charged
polyamide fan guards;
IP 44 protection grade;
class F insulation;
internal thermal contact protection;
operating temp. -35 °C - +40 °C.
The versions with standard electric defrost (ED) are equipped with stainless steel heaters with vulcanised terminals
preset for 400V/3/50-60 Hz connection.
The electric parts and casework are connected to a grounding terminal, the wiring of the motors and heaters is
carried out in separate IP 54 protection grade junction boxes.
For special applications and further information consult our Technical Dept.
