Damen ASD 3213
The Damen ASD Tugs Hull 3213 is designed to be highly manoeuvrable, sail in choppy seas with no loss of stability and operate in a very environmentally friendly way.
For the wheelhouse and accomodation, an air conditioning system was selected with one air handling unit with an optional heating section and one seawatercooled condensing unit built together on a common frame. The wheelhouse has its own temperature control system (Variable Air Volume system) and temperature controlling is independent of the rest of the system. Thanks to the VAV system in the wheelhouse, the ventilator of the air-handling unit is speed controlled by a frequency drive. In addition, there is a separate air-conditioning system serving the main engine control room, consisting of a seawater-cooled condensing unit and direct expansion air handler.
