1. Double Chopping System (First Chopping)
The first chopping system consists of two chrome steel blades  fixed on the body inlet, acting in contrast to a spiral conveyor made from high grade cast iron and fitted to the motor shaft. Both materials undergo specific hardening treatments. With a speed of 1750 rpm, this is the first and only chopping system that operates at over 170 cuts per second!
2. Double Chopping System (Second Chopping)
The second chopping system consists of a shear cutting plate in special high grade cast iron that acts in contrast to the sharp profile impeller blades  also in high grade cast iron. Both materials undergo specific hardening treatments.
3. Double mechanical seal
Mechanical seals in silicon carbide and graphite-ceramic. 
4. Thermal probe sensors
Double thermal probes, immersed in the stator, prevent overheating of the electric motor and preserve its operating life.
6. High efficiency hydraulics

Hydraulics are designed to correlate high efficiency (up to 77%) with high chopping and anti-clogging performance. Data according to UNI EN ISO 9906 Standard.
