The straight line wiper PG-Ext is a system with external installed motor, contained in a watertight casing IP67. The motor is equipped with an electronic speed regulator able to communicate with other devices via the CAN bus. The wiper PG-Ext is designed to ensure:
- two operation modes: continuous and intermitent running with the arm movement synchronized and maximum speed running for each wiper. The operating conditions are stabilized by the speed regulator in a wide range of voltages;
- low maintenance need and high strength for extreme marine conditions;
- rational wiring thanks to the control unit used both to contain electronic speed regulator and as a distribution box. The control unit can also be used to feed auxiliaries like water/air electrovalves and wiper frame heating elements. In case of maintenance it is possible to remove the electronic speed regulator without interrupting the CAN bus communication between wipers;
The wiper PG-Ext is also available with double arm (type PGD-Ext). On request these systems can be equipped with spray nozzles (option PG.ZZ) and with heated frame (option PG.HOT).
