Function If installed in areas where noise emissions are critical, the CHP module can be equipped with a ventilated

silencer hood, consisting of the silencer hood for the engine generator unit and the casing of the heat

exchanger unit.

Version • Sound insulation elements made of sheet steel, lined with combination elements made from bitumen

board and highly absorbent exible foam with additional surface coating; area in contact with hot parts

lined with compound foam (300 kg/m

) with additional aluminium lining.

• The 25 μm thin coating is largely resistant to petrol and motor oil splashes and easy to clean.

• The surface coating protects against mechanical damage and has outstanding ageing resistance.

• Fire characteristics in accordance with FMVSS 302 and DIN 75200.

• In the hot area, the insulation is made of mineral wool/glass bre and a perforated plate cover.

• The silencer hood elements can be removed for maintenance.

• The support structure can be removed for modication work, in order to be able to work with lifting

gear without hindrance.

• Fresh air inlet through louvres integrated into the side silencer hood casing. Combustion air inlet

through separate air inlet on the roof casing.

• 1 runtime-controlled extract fan.

• In addition, 1 temperature-dependent extract fan to supply the CHP module with sufcient combustion

air and cooling air at max. 500 Pa pressure for extract air duct.

• Average sound insulation of the hood approx. 20 dB.

• Flexible canvas ange to connect the downstream duct.

Delivery As loose accessories or mounted on the CHP module
