1.2 GENERATING SETS FOR VEHICLES
1.2.1 Marine and mobile generators
Whisper Generators originate from the marine sector. But
there are also specially designed Whispers available for
mobile applications, suitable for supplying power on board
of vehicles to use professional apparatus and equipment,
strong lightning and air conditioning etc. The cooling
system and exhaust system on vehicles is completely
different from standard marine systems. Standard marine
generators are cooled by seawater that nowhere exceeds
30° Celsius and is seldom warmer than 20° Celsius in the
northern territories. Cold seawater is pumped through the
alternator, through the heat exchanger and is injected in
the exhaust. The exhaust gasses are therefore cooled and
rubber exhaust hose can be used.
On vehicles the engine and alternator are individually
cooled by radiator with an electric (12V/24V or 230V)
driven fan. The radiators can be fitted below, on top or in
the side of the vehicle.
The exhaust is of the dry type and includes a stainless
flexible bellow and high quality mufflers.
Never use rubber exhaust hose, neither
fibreglass nor plastic exhaust parts in a dry
exhaust system as applied on vehicles.
