Dometic Smartstart

Eliminate Boat Air Conditioning Start-Up Spikes

Dometic Smartstart
The Dometic SmartStart is a unique device that smooths out startup power demand of the boat air conditioner's compressor, reducing amp requirements by up to 65%. The technology uses dynamic feedback control to reduce the inrush of current by starting the compressor motor slowly, thereby eliminating current surges that could affect the operation of an overstraing power source. No other soft starter in the industry provides better performance.

Air Conditioners for Marine Applications - What You Need to Know

Whether you are sailing for a day or a year, your boat needs to have a dependable air conditioner so you can stay cool and comfortable. The weather can be stifling when you are on the open sea. When combined with the humidity, your body may not be able to cool down right away. That is where our high-quality marine air conditioners come in. Our best-selling brand comes in a variety of models perfect for staying cool on your yacht

How to Find the Best Marine Air Conditioner

There are several important factors you will need to consider when choosing a marine AC unit. The air conditioner's capacity, energy consumption, noise level, and features will play a big role in your decision. Not every air conditioner is compatible with every boat. Here are our pro tips to remember when shopping for a Dometic marine air conditioner.

Capacity Is Important for Marine AC

Different air conditioners have different cooling capacities. You need to measure the size of the room where your AC is going and match it against the air conditioner's capacity. Our air conditioners deliver 4,000 to 72,000 BTU of cooling power per hour and are 27 percent more energy efficient than similar models from our competitors .

Innovative Features in Our Marine AC Units

We use state-of-the-art engineering in all of our marine air conditioners. From the environmentally friendly refrigerant R-410A to our innovative solution to reduce vibrations in your space, you can rely on our efficient units to maintain a comfortable indoor climate, while without taking too much space Some features include rust-free drain pans, hermetically sealed units, and vibration isolation mounts.

Why Choose Dometic?

Our marine AC systems are sold in over 100 markets. Many world-renowned yacht and sailing manufacturers choose our products for interior climate control. Our products require minimal maintenance and are engineered to withstand any harsh marine environment. The housing and components resist corrosion from saltwater and withstand temperatures of up to 140 degrees Fahrenheit.

How Much Power Do Marine Air Conditioners Need?

Our air conditioners come in different sizes to suit your for marine needs. They require anywhere from 115 volts at 60 Hz to 230 volts at 50 Hz. It is important to verify that your boat's battery can consistently deliver the level of power required to the air conditioner.

Do Marine AC Units Take Up Too Much Space?

We understand that interior space is at a premium on all types of boats. Our marine air conditioning systems are designed to be as compact as possible. They mount in line with the interior panels and conserve space. The tubing can be run inside of the interior walls or along the ceiling. The electrical box and compressor units take up to 25 percent less space compared to those made by our competitors.

What is Zoned Climate Control?

Zoned climate control allows you to set different temperatures for different parts of your boat. If one member of your party wants their cabin to be cool and another wants theirs to be several degrees warmer, zoned climate control makes this possible. We offer multiple zoned climate control air conditioners for marine applications. The condenser goes in the engine room and the smaller, quieter evaporator units are wall-mounted in the different zones. You can choose up to six zones during your setup.

Heating Functions on Dometic Marine Air Conditioners

Some of our marine AC units can also be used as mini heat pumps. They can heat or cool any space. This is helpful for chilly nights and hot days at sea. Our ECD and Turbo Series products offer both heating and cooling functions for marine applications.
