Silent Plus

Silent and Quieter Generator Sets, with even more running time for the rental sector

HIMOINSA's engineering team has envisaged important enhancements for applications within the rental sector in the form of silent generators. The range includes generator sets that use engines from Yanmar, FPT and Scania. They cover a power range between 20 and 550 kVA.

GENSETS DESIGNED TO WORKING LOCATIONS WITH GREATER ACOUSTIC RESTRICTIONS, specially in urban areas. Silent Plus generators, in addition to complying with the Stage IIIA emission regulations, guarantee a noise level of around 60 dB(A)@7m. Mainly focused on the events sector, the Silent Plus range guarantees low levels of sound emissions thanks to a more optimized design of the air intakes and outputs, the addition of a dual core exhaust system, and top-quality insulating materials.

DUAL CORES exhaust system: reduces sound emissions by optimizing the space available in the canopy.

High soundproofing levels

Canopy soundproofed with high-density,100mm thick rock wool.

Control panel insulation

It remains insulated from the rest of the compartment to avoid noise emissions when the door is opened to manipulate the panel.

Power outles

Powerlock outlets (optional) with 100% of the genset's rated kW capacity, for quick, simple and safe connection.

Simplify the maintenances

Steps and hand-grips that facilitate access for maintenance purposes in largest models

Rain  protections

All the canopy's attachment points have a special seal to prevent water from getting in.

Coolant sensors 

Generator sets with FPT and Scania engines include low level coolant sensors for an even more accurate control. (Optional in Yanmar series.)


HIMOINSA Silent Generators can last for more than four working days without refueling, thanks to high-capacity tanks and engines with electronic injection control.
