How To Choose the Right Superyacht Chiller 

MTD Series 

A reliable and ample air conditioning system is essential in any 

superyacht design. No matter how elegant the surroundings, 

they won’t feel luxurious if the temperature of the living area is 

less than comfortable. Not only will the right air conditioning 

system provide a pleasant voyage for passengers and crew, 

but it will also maintain the required temperature range for the 

operation of critical electronic equipment. 

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 vessel itself. 

Assessing real-world air conditioning requirements takes 

experience and specialized knowledge, so look to Dometic 

Marine 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. 

The Three Biggest Challenges When Choosing the Right 

Manufacturer 

Challenge #1: Engineering Support 

Trust Dometic’s expert engineering team to review your 

drawings and specifications to ensure all measurements 

and load calculations are correct. Or, we can layout your 

entire system, size all the appropriate capacities, and design 

the most suitable system for your vessel. Dometic can also 

supervise the installation of your air conditioning system and 

provide on-site training and complete documentation to your 

crew. 

Challenge #2: Broadest Selection 

Dometic provides the world’s broadest range of chilled water 

systems, including air handlers and controls. Our chillers 

provide up to 2.88 million BTUs of cooling or heating and come 

in a variety of configurations, with custom designs available.

Superyacht Chilled Water System 

Internet 

Home/Office 

Monitoring and control of the chiller and 

individual air handlers (with optional CAN 

bus adapter) over the internet is possible 

with the ethernet capability of the on-board 

Chiller Gateway Network Interface (pg. 13). 

A seawater-cooled chiller, installed in the engine room, cools or heats the ship's interior via a loop of chilled or heated fresh water. Along 

the fresh-water loop are the air handlers, which blow cold or hot air, and also dehumidify the environment. 

The air-cooled Radome ECU (pg. 17) 

keeps critical navigation equipment 

inside the radar dome running at 

optimal temperatures. 

Air handlers are designed to be installed in tight spaces such as walls, storage areas, and overhead spaces, 

then ducted to the various cabins, corridors, and living areas. Fresh Air Makeup Units can be installed and 

ducted to the return stream of air handlers to help improve air quality throughout the vessel's interior. 

Cabin temperature, fan speed, and humidity levels are controlled and monitored by 

sophisticated digital cabin controls. Chiller operation, water temperatures, faults, and 

other information are monitored by the Tempered Water Logic Control (TWLC). 

The optional Chiller Gateway Network 

Interface (pg. 13) provides local or remote 

control and monitoring of the chilled water 

system. The Gateway is available with 

graphical color touchscreen.

Control Unit (ECU) is specifically designed 

to work within the radar dome enclosure, 

ensuring optimum temperatures for the 

critical equipment inside. The cool-only 

capacity of the ECU is 16,000 BTU/hr. 

n Corrosion-resistant coating. 

n Solid-state digital control. 

n Lightweight and easy to install. 

n Raised lance fin and rifled tubing 

for maximum capacity. 

n High-efficiency rotary compressor. 

In-Duct Breathe Easy Air Purifier 

Key Benefits 

Although small and lightweight, the 

easy-to-maintain Radome ECU features 

rugged construction with corrosionresistant 

materials able to withstand the 

most extreme conditions at sea. 

n 3 configurations: Self-contained 

interior dome, self-contained 

remoted ducted, and split gas. 

Stops Odors & Reduces Unhealthy Contaminants 

The in-duct Breathe Easy Air Purifier uses innovative 

Photocatalytic Nano-Mesh technology with ultraviolet (UV) 

light to improve air quality. The intense UV light produces 

no harmful ozone. 

Customer Testimonial 

"After cleaning up a diesel fuel leak from the generator, we still had 

a persistent petroleum odor. I installed the portable Breathe Easy Air 

Purifier in the galley. A week later all odors were completely eliminated." 

— John H. Thommen, Guilford, CT

With Individual Ducts for Each Pane of Glass 

Dometic's Pilot-House Defroster incorporates individual 

ducts to treat each individual pane of glass. 

The defroster has two modes of operation: fan-only mode 

which supplies ambient cabin air when only ventilation 

is needed; and fan-with-heat mode which incorporates 

thermostatically controlled electric heat. Custom designs 

are available.

Auxiliary Heat Module 

Key Benefits 

VOCs, bacteria, fungi, 

mold, pollen, and fumes 

Non-ozone-producing UV light 

reduces biological contaminants like 

mold spores, bacteria, and viruses 

that pass through the air purifier 

system. 

Photocatalytic Nano- 

Mesh structure 

UV light energy activates the titaniumdioxide 

catalyst on the surface of the 

nano-mesh structure. The molecules 

of pollutants and odors that come in 

contact with the catalytic nano-mesh 

Harmless water vapor 

and/or carbon dioxide 

structure are reconfigured into nontoxic 

elements. 

Significantly cleaner, healthier air 

exits the system. 

Provides Heat In Extremely Cold Waters 

Dometic's auxiliary electric heat modules work with 

chilled water systems to provide additional heating when 

the vessel is in extremely cold seawater. They also provide 

heating when the chilled water system is in cooling mode.

Toilets for VacuFlush ® & MasterFlush ® Systems 

Powerful, Odor-Free Operation in Modern, Luxurious Styles 

SeaLand's residential-style toilets for VacuFlush ® and MasterFlush ® systems offer modern 

elegance, attractive features and a variety of flushing options (see comparison chart below). 

4600/8600 and 4800/8900 series toilets feature a streamlined design in a small footprint. 

Flat (4600/8600) or sloped (4800/8900) bulkhead-mating profiles are available, as well as 

standard-height and low-profile models. A “soft-close” seat is standard. 

For deluxe comfort and style, 4700/8700 series premium toilets feature an elongated seat 

and bowl, making them ideal for larger boats. They are available in standard-height, flatback 

bulkhead-mating profile only. 

Key Benefits 

n All-ceramic, easy to clean. 

n Minimum flush function prevents 

sloshing. 

n Variety of electronic flush options. 

n Residential-size seat and bowl. 

n Low-profile models available. 

n Through-floor or through-wall 

discharge. 

n Colors: White or bone. 

Two Types of SeaLand ® Flushing Technologies 

VacuFlush ® System 

VacuFlush ® toilet systems are one of the most popular systems 

preferred by boat manufacturers and owners around the world. 

VacuFlush technology uses stored vacuum energy to clear the bowl 

instantly and propel waste to the holding tank. This results in no 

odors, no clogs, and exceptionally low power draw and water usage. 

VacuFlush systems feature a selection of components and options 

that offer home-like comfort, style, and performance. Multiple-head 

VacuFlush systems can be specially engineered to accommodate 

individual yacht requirements, including centralized sanitation 

system monitoring and control.

MasterFlush ® System 

Dometic’s industry-leading MasterFlush ® system pulverizes waste 

with less power than competing toilet systems. 

The stainless-steel 18-blade macerator turbine grinds waste into a 

fine effluent with no clogging. The macerator pump propels effluent 

to the holding tank, which can be installed up to 98 ft. (30 m.) away.

SeaLand's integrated toilet/bidet and free-standing bidet are designed to 

match VacuFlush 4800/MasterFlush 8900 series toilets. 

The integrated model produces a gentle, aerated water flow even if water 

pressure fluctuates. The freestanding model accepts standard faucet 

hardware, supplied by the boat builder or owner. 

VacuFlush 4700/MasterFlush 8700 Series premium toilets with 

elongated seat and bowl in bone and white 

Superior technology means 64% less power consumption and 33% 

lower amps per flush than competing models. In addition, the homestyle 

water trap in many MasterFlush models keeps drainline odors 

away from living spaces.
