00% Fresh Water-Cooled (Ignition Protected for gas vehicle applications) The most significant advantage of the Fischer Panda vehicle generators is the very low sound level. There are many combined factors that produce this result. The most important fact is that the engine and alternator are completely freshwater-cooled,. No cooling air flow inside of the capsule is required. Because there is no requirement for air, with the exception of a small air intake for combustion, your Fischer Panda will be the quietest generator you’ll never hear. This small quiet and efficient system is perfect for your medical, broadcast or specialty vehicle needs. Horizontal or vertical radiator options can be mounted on the roof or side of the vehicle.
