Unlike many marine air conditioners, the CTM CT-6HS focuses on performance without compromise. Here’s why it’s a top choice:
Soft Start Advantage
The soft start system ramps up the compressor in four phases, significantly reducing initial power draw. This allows you to:
Operate on smaller generators
Run multiple appliances simultaneously
Sleep comfortably without generator noise
Corrosion-Resistant Design
Titanium circulating coils outperform copper by 40% in corrosion resistance, making them perfect for saltwater environments. The stainless steel frame and ABS pan further enhance durability, preventing rust and structural degradation over time.
Universal Compatibility
The CTM CT-6HS works seamlessly with most marine controllers and thermostats, including:
Dometic
Cruisair
Marine Air
Micro Air
This universal control board ensures easy replacement and retrofitting without complicated rewiring.
Compact and Lightweight
At just 41 lbs (19 kg), this unit fits into small spaces without sacrificing power. Its rotatable high-velocity blower (up to 250°) ensures rapid and even cooling throughout the cabin.
Installing or replacing a marine air conditioner can be challenging, but the CTM CT-6HS simplifies the process:
Drop-In Replacement: Compatible with part numbers from Dometic DTG6, DTU6, Cruisair STQ6, STX6, Marine Air VTD6K, and more.
Ducting Considerations: Minimum duct diameter 4 in / 102 mm; cinch down with standard clamps for tight fit.
Seawater Pump: Recommended CTM PM500LH 500 GPH, 230V for optimal water flow.
Control Compatibility: Works with Elite II, Smart Touch, Passport I/O, and SMXir controllers.
Pro Tip: Always verify waterline connections and ducting sizes before replacing older models to prevent installation delays.

Expert Insight: The CTM CT-6HS delivers superior efficiency and longevity thanks to its corrosion-resistant materials and soft-start technology—features often lacking in older Dometic or Cruisair units.
Maximize Efficiency: Run the soft start feature during peak power usage to reduce strain on your generator or shore power.
Regular Maintenance: Inspect titanium coils and clean seawater intake regularly to prevent scaling and maintain airflow.
Reverse Cycle Heating: In colder climates or night use, switch to heating to maintain cabin comfort without auxiliary heaters.
Noise Reduction: Ensure the blower rotation is unobstructed; small adjustments can improve quiet operation significantly.
Boaters consistently report that the CTM CT-6HS is the ideal choice for both sailboats and powerboats requiring compact, reliable, and quiet climate control. Its combination of soft start technology, universal compatibility, and anti-corrosion design makes it a superior long-term investment.
Example: A 40-foot sailboat replacing its Dometic DTG6 with a CTM CT-6HS reduced electrical load by 30% while maintaining consistent cooling—even during peak summer temperatures.
