SU window wiper


SU window wiper shall be used on large sized windows (arm length up to 1200 mm) on boats for civil and military applications, for a particularly heavy duty.

The motor unit is characterized by a compact size, despite having a torque of 80 Nm, easy wiring and maintenance. It is equipped with an internal power relay, which allows it to be operated via a low current switch (Model SU), and it can be equipped with an electromagnetic brake that firmly fix the arm in park position (Model SFU), a suitable solution if the arms are particularly stressed by the air flow. It also ensures a variable wiping angle and self-parking position side.

SU wiper system is constructed out of non-corrosive and top-quality materials and extensive customization of finishes is available. It complies with the IEC 60945 standard.

Control system is traditional UC system control panel or standard switches.



  • Available rated voltage:  24 Vdc, 110 Vac, 220 Vac;
  • Superior components are used to ensure long lasting systems;
  • Adjustable wiping angle and self-parking position side.
