BRUNO has designed the WHISPER Series paying attention especially to following features: low noise level, innovative VSi cooling system controlled by its special variable speed fans with electric radiator, high LAT (> 55° C) and low fuel consumption.


The WHISPER SERIES includes :

WHISPER CUBE Soundproofed generators in ULTRASILENT CANOPY


WHISPER BOX generating sets range from 800÷1650 kVA and they are soundproofed in an innovative type of 20’ container to make them also safe, easy to use and transport.

They are equipped with the technologically advanced VSi cooling technology which consists of electric radiators characterized by a large radiating mass and multiple VARIABLE SPEED fans with INVERTER.

In the generating sets with conventional cooling system ALMOST ALL of the air used for cooling goes from the engine/alternator area to the radiator area. The radiator fan, mechanically connected to the crankshaft, runs at FIXED SPEED. In this way the fan’s absorbed power is always at its MAX and CONSTANT levels, even when the conditions of use do not require it.

WHISPER BOX is characterized by its three sections fully isolated from each other: silencer , engine / alternator , and cooling 3 . The silencer room does not exchange heat with the engine / alternator compartment so that the LIMIT AMBIENT TEMPERATURE increases. Furthermore, the flow of air coming from the engine / alternator compartment does not go through the muffler room and therefore contributes to a partial cooling of the mufflers themselves. Quiet electric fans for best noise reduction (1) Indirect air flow (2). Smaller air flow openings.
