COMMAND PANEL

Made in metal box, IP54 degree, with lock. The control panel is equipped with the
control ComAp AMF25, equipped with the possibility of starting and stopping the generating set, both in automatic mode and in
electric module. The control module monitors the power grid and can command and control the AAR panel
(automatic reserve release).

Housing

Made of galvanized steel, painted in electrostatic field, soundproofed. It is modularly designed with
access doors inside on all sides of the generator. The exhaust pipe is a residential type, mounted in
inside the housing.
The housings are designed to optimise cooling of the engine and alternator assembly and can be fitted in
outdoor, providing protection against the weather, and low noise. Painting is carried out
with polyurethane paint with UV protection.
