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.
• Sound insulation elements made of sheet steel, lined with combination elements made from bitumen
board and highly absorbent flexible foam with additional surface coating; area in contact with hot parts
lined with compound foam (300 kg/m
• 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 fibre and a perforated plate cover.
• The silencer hood elements can be removed for maintenance.
• The support structure can be removed for modification 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 sufficient 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 flange to connect the downstream duct.
