All cooling capacities shown below are based upon a standard installation. Maximum outside temperature is 95 degrees Fahrenheit (35 degrees Celsius) with a minimum interior cabin temperature of 72 degrees Fahrenheit (22 degrees Celsius). If you desire any other temperatures than these use the Aqua-Air Quick-Calc program. You can download this free program by clicking here.
To determine the correct Self Contained Unit for your boat complete the following steps:
Determining the Correct
Self Contained Unit Size for
On the chart below find the appropriate Area Type listed and then scan to the right until you find the Volume of Area range that would include the volume of your area. Click on the correct Volume of Area and the information for the correct self contained unit will appear.
Example: A Mid Deck ( B ) area that has a volume of 520 ft3. The correct unit capacity for this area is the 10,000 BTU/H unit. Clicking on the range 471 - 670 in the "Mid Deck" row will now display all of the information for the 10,000 BTU/H Self Contained Unit.
Example: A Pilothouse area that has a volume of 13.7 m3. The correct unit capacity for this area is the 12,000 BTU/H unit. Clicking on the range 12.0 - 14.2 in the "Pilothouse" row will now display all of the information for the 12,000 BTU/H Self Contained Unit.
Determine the overall Volume of Area that you want to cool. To calculate the volume of the area, multiply the length of the room by the width and then by the height.
Example: If the room is 15 feet long, 10 feet wide and 7 feet high, the volume of the room is 1050 ft3 (15 x 10 x 7 = 1050 ft3 ). If a room is narrower at one end than the other, take the average of the room.
Example: A stateroom is 16 feet wide at one end and 12 feet wide at the other end. The average width is 14 feet ( [16 + 12] / 2 ).
Pick the Area Type that most closely matches one of the five areas shown in the charts below. The Pilothouse and Galley areas are listed separately because these are usually areas with unusually high heat loads. Shown below are examples on some common boat types.
Volume of Area to be Cooled
To order a complete Self Contained Unit System order one item from each section:
Self Contained Unit
Thermostat (match voltage and type, manual or digital, to the self contained unit voltage and type)
Seawater Pump (match voltage to the self contained unit)
Grille and Duct Kit
