PG-EXT window wiper

MAIN DESCRIPTION

The straight line wiper PG-EXT should be used on windows of any size, usually with wide base length, for heavy duty applications. These wipers consist of a motor unit, mounted externally, in order to safe space inside the bridge, contained in a watertight casing IP68. Each component is custom made for each window and application.

This system is constructed out of non-corrosive and top quality materials and extensive customization of finishes is available. It complies with the ISO 17899 compliance.

PG-EXT Model is equipped with an electronic speed regulator able to communicate with other devices via the CAN bus. It is possible wipers and auxiliary operation as single unit or a groups and from different points of the deck of the ship. PG-EXT window wiper is designed to ensure two operation modes: continuous and intermittent running with the arm movement synchronized and maximum speed running for each wiper. Optimal visibility is guaranteed even in the worst conditions and a cleaning area greater than 85%.

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).

Control Panel Features

Operation ModesOperation with panel: CAN bus commands is generated from a control panel, with a standard keypad proposed by us

Operation with gateway: CAN bus commands is generated from a gateway connected with switches installed by the customer on the consolle
Direct operation: CAN bus commands is generated directly from the integrated bridge system
Number of WipersAdvanced control allows to operate up to 12 groups from 1 up to 8 wipers.

It allows a perfect synchronization of the wipers in all operating conditions, both in continuous and intermittent operation mode. Synchronization occurs even if the wipers are different in dimensions and wiping angles.
Number of AuxiliariesThe DCS system provides the possibility to drive auxiliary devices that normally equips ship bridge, like elvalves of window rinse system, glass heater and wiper heater contactors and other devices. Each motor/control unit can manage 1/2 auxiliaries. For centralized management of auxiliaries, we offer an auxiliary devices control unit, DCS.AUX4, a relay unit controlled by CANbus messages, which provides 4 power outputs to drive such auxiliaries.
