All HTE units are equipped with multi-blade fans with high energy efficiency in accordance with the Ecodesign Directive (EU Regulation No. 327/2011).
The electric motors are thermally protected and have protection class IP54, IP55 according to IEC / EN 60529 / DIN 40050.
Axial fans with external rotor are maintenance-free, sealed bearings DIN 6252 are lubricated for life, statically and dynamically balanced to ISO 1940/1.
The windings have insulation class F, which varies by up to a class H for the most severe conditions of use.
The conditions of permissible operating range from -30 ° C to 60 ° C for the configurations in standard engine. Motors for high temperatures are available upon request.
Three-phase motors are ready for double connection with two speeds of rotation (Y, Δ, or with switching device).
All fans are designed to be combined to control systems of voltage or frequency for the modulation of the rotation speed and the control of the sound level.
The fans are available in 5 power sizes to ensure excellent performance by combining installed capacity, noise level and respect on consumption.
AXIAL FANS ADVANTAGES:
AC and brushless EC electronic modulating versions.
Frequency 50 or 60Hz
Pressing operation in hot or reversible function of air flows to increase the effectiveness of defrost
Available for high temperatures or according to ATEX regulations
Special versions for high external pressure centrifugal fans or ducts are available too.
