Subbase Fuel Tank Features

• The fuel tank has a black powder-coat finish texture. D The above-ground rectangular secondary containment tank mounts directly to the generator set, below the generator set skid (sub base).
• Provides walking surface within enclosure for generator set access.
• Both the inner and outer tanks have UL-listed emergency relief vents.
• Flexible fuel lines are provided.
• The containment tank’s construction protects against fuel leaks or ruptures. The inner (primary) tank is sealed inside the outer (secondary) tank. The outer tank contains the fuel if the inner tank leaks or ruptures.
• The above ground secondary containment subbase fuel tank meets UL 142 requirements.
• Oil fogged tank interior for rust prevention.

Aluminum Sound Enclosures

• Rimless enclosure roof to reduce the buildup of moisture and debris.
• Internal exhaust silencers offering maximum component life and operator safety.
• Service access. Multiple personnel doors on both sides for easy access to generator set control and servicing of the fuel fill, fuel gauge, oil fill, and battery.
• Cooling/combustion air intake. Fixed air intake louvers.
• Sound-attenuating design using internal silencer and added acoustic insulation, UL 94 HF1 listed for flame resistance.
• Vertical air discharge. Sound level 2 (SL2) models use a vertical air discharge design that redirects exhaust and cooling air up and above the enclosure to reduce noise.
• Enclosure is capable of being split into three sections with one section independently removed in the field if major generator set component replacement is required – significantly reducing service costs and downtime.
