At Webasto we have an Air Conditioning system to suit every boat. Our BlueCool Classic range of Self Contained Air Conditioning units are the ideal solution for single cabin cooling, with all of the components neatly mounted on a compact frame.

Our BlueCool Premium range of Chilled Water Systems offers a multi cabin cooling solution from the smallest boat to the largest Super Yacht. A centrally located chiller cools water before it is circulated around the boat to air handlers, which cool the air and blow it into the cabins. The temperature in each cabin can be controlled via independent controllers making the system very versatile.

As a general rule we would use Self Contained units to cool three or less cabins, with a unit installed in each cabin and a single raw water-cooling pump supplying the units via a pump relay. This type of system is easy to install and less expensive than a Chilled Water System.
When four or more cabins require cooling, it becomes more economical to consider a Chilled Water System. This type of system will generally take up less space in the cabins and is far more suitable for a multi cabin installation.

The outlet grilles on any Air Conditioning System should be installed at the highest possible point in the cabin, to allow the best possible cooling effect. This principle is the same on a climate control system. Whilst warm air rises, the blower capacity on an Air Conditioning System is up to three times higher than on a heating system and providing the return air grilles are low down the air flow is sufficient to provide a good heating output, despite having high outlets.

There are a number of ways of reducing air noise in the individual cabins, firstly it is important to fit the minimum required size of air grille in the cabins as they are correctly specified to provide maximum air flow with minimum noise. We also recommend the use of a transition box to spread the air evenly over the grille. Via the digital controls it is also possible to reduce the blower speed in individual cabins, however lower blower speeds do cause a reduction in BTU output.

If the unit is installed directly underneath a bed it will require plenty of sound insulation to lower noise levels. It is also inadvisable to put a grille directly in front of the unit, as this will allow the noise of the unit to escape directly into the cabin. To solve this problem the grille should be offset from the unit preventing the sound from entering the cabin.

Webasto offer a full two-year guarantee with all of our Air Conditioning products. We are active in over 56 countries worldwide, with an extensive dealer network widening our coverage further still.

It is possible to provide heat through an Air Conditioning system using a reverse cycle valve. However this method is only efficient when the ambient temperature of the cooling water is above 10°C and stops working completely when the ambient temperature of the cooling water falls to 4°C.
Webasto are able to offer a Total Climate Control System, our BlueComfort solution, which utilises a specially engineered diesel heater within the Air Conditioning System. Using this method we are able to provide the selected temperature regardless of the ambient temperature of the cooling-water. The heater is fully integrated and is controlled via the Air Conditioning controller.

It is possible to do this but it would require two separate, parallel water circuits, one for heating and one for cooling and on smaller boats this is impractical. However we can get around this problem by installing a/c heating elements inside the individual air handlers, allowing heat to be provided individually in each cabin.
