The Critical Role of Yacht Air Conditioning The Three Biggest Challenges When Choosing the Right Company

In any yacht design, especially in the design of
a super yacht, air conditioning plays a critical
role. No matter how elegant the surroundings,
they won’t feel luxurious if the temperature
of the living area is less than comfortable. It is
wise, therefore, to engineer the air conditioning
system for the unique characteristics of
each yacht, and address climate control
with as much attention and expertise as
you give to the design of the yacht itself.

Capacity From 16,000 to 2.52 Million BTUs

For Yacht Lengths of 20m to over 90m

Dometic’s chillers range in capacity
from 16,000 to 2.52 million BTUs. To
meet many unique needs, systems
are available in a variety of styles, such
as compact units, modular staged
units, and mammoth tube-and­shell systems for very large yachts.
Custom chillers can also be designed
to meet special needs.

Occasionally, naval architects, builders, and
owners do not have the experience and
specialized knowledge it takes to assess real­world air conditioning requirements. Look to

Dometic for the resources and

expertise you need. Our

senior engineers can

design your yacht’s air

conditioning system

or review your design
and specifications to
make sure everything

is correct.

Dometic’s Environmental Policy

We are committed to minimizing the environmental
impact of our products through regular assessment
of energy and material demands, emissions, waste
generation, and recyclable resources.

For many years we have proudly displayed our

Dometic leads the industry in the development of globally
compliant marine air conditioning systems.

Chilled Water Air Handlers

Featuring WhisperCool Technology

WhisperCool Technology eliminates the annoying

“motor hum” from traditional air conditioning blowers that

occurs at very low speeds. Incoming alternating current is

converted to drive a high-efficiency, brushless DC fan motor.

The result is a much quieter fan operating across a broad

range of variable speeds, permitting the user to select the

desired comfort level. Additional improvements eliminate

condensate drain problems. Better dehumidification,

better cooling, less noise…just the kind of performance

one expects aboard a luxury yacht.

AT-DC Air Handler:

■

Advanced, super-quiet variable speed DC fan motor.

■

Engineering improvements eliminate condensate drain

challenges—a positive-flow drain pan, larger drain

connections, offset coil from drain-pan edge, and a

redesigned bypass valve.

■

Improved coil design for better dehumidification and

cooling.

■ 

More accessible maintenance points.

ATL and ABL Air Handlers:

■

Height-saving design is ideal for over-head

applications.

■

Suspend from above or support from beneath.

■

Vibration isolation included.

■

Heater elements accessible from underneath.

■ 

Bypass valve has removable power head for simple

servicing.

■ 

Valve body is soldered to unit to prevent leaks.

ATV Air Handler:

■
