Product informations
Particularity and preciousness of the AZN EC series can be summed up in the following characteristics:
- External casing, with simple and robust structure, in pre-painted galvanized steel.
- Diffuser with individually adjustable fins, for optimal distribution of hot air.
- 3-row heat exchange coil, with fittings for water connection and manual vent valves.
- Axial fan driven by EC motor (electronic commutation motor) with integrated electronic converter, for a fine modulation of the rotation speed, based on the actual need for heating.
- Significant electrical savings (up to 70%), thanks to the low consumption of the EC motor.
- High acoustic well-being, consequent to the modulation of the fan speed.
- Easy to use control panel, with integrated temperature probe.
