Description
Mermaid Marine Air M9 (230V Cool Only Variant) Self-Contained Marine Air Handler
Featuring a dedicated 9,000 BTU/h cooling capacity, the Mermaid Marine Air M9 (230V Cool Only Variant) engineering configuration optimizes tropical climates inside warm stateroom environments up to 350 cu.ft. Utilizing compact 11.5×16.0x12.0-inch physical dimensions, this heavy-duty self-contained system drives a steady 300 CFM evaporator airflow through a standard 5-inch duct connection. This cool-only commercial-grade design guarantees absolute thermal regulation without unnecessary internal heating loops, functioning as an exceptional alternative to an automated low amp marine air handler layout.
Technology built into the electrical control board ensures seamless management over a single-phase 230V power supply grid operating at 50/60Hz. The internal architecture monitors a continuous 3.6A full load cooling amperage and accounts for a 15A locked rotor startup spike, demanding a 15A circuit breaker during standard load conditions. Safe operations under marine environments are secured by a 5/8-inch seawater plumbing pipe connection requiring an optimal water pump delivery rate of 3.33 GPM through a robust cupronickel condenser loop and a stainless steel frame.
Core Engineering and Performance Elements of Mermaid Marine Air M9 (230V Cool Only Variant):
- High efficiency 9,000 BTU dedicated cool only capacity architecture
- Compact 11.5-inch physical height profile fits restricted storage lockers
- Premium grade cupronickel condenser loop prevents seawater corrosion
- Marine grade stainless steel base pan eliminates bilge rust damage
- Efficient 3.6A full load cooling current draw profile
- Hermetic rotary compressor engineering dampens localized vibration sound effectively
- Standard 5/8-inch seawater inlet and outlet plumbing connections size
- High output internal blower drives 300 CFM ventilation air
- Lightweight 49 lbs chassis simplifies self contained installation layout
- Pre charged eco friendly R-410A system refrigerant tracking loop
Advanced Thermal Exchange Performance
Cupronickel condenser loops provide maximum thermal transfer across small-craft saltwater loops by countering scaling build-up. The specialized mechanical engineering balances automated refrigerant pressures across an optimized cooling surface, sustaining peak operating performance. This durable combination eliminates unexpected climate drop-offs under punishing high-salinity oceanic operational cycles, acting as a premium corrosion resistant boat AC platform.
Two Year Factory Warranty Protection
A comprehensive 5-year factory warranty protects your entire marine air conditioner investment against unexpected mechanical component failures. Factory certified technicians authorize immediate structural coverage for verified electrical and mechanical parts defects from the initial retail transaction date. Onboard operators receive absolute long term security, minimizing operational downtime while maintaining constant vessel comfort.
Vessel Layout and Application Fit
Vessels measuring 20-28ft achieve ideal climate stability using this compact self-contained climate control configuration. The physical layout is custom-tailored for international power distribution profiles requiring a minimal 2.0 kW generator footprint. Proper installation ensures optimized structural airflow, maximizing onboard living space while reducing internal equipment strain.

Mermaid M9 Cool Only 230V FAQ
How much does Mermaid M9 weigh?
Mermaid M9 weighs exactly 51 lbs total net weight. This streamlined cool-only variation removes heavy internal reversing valves, reducing structural weights on small luxury watercraft while delivering a full 9,000 BTU of heat-reversing air conditioning capacity to combat brutal tropical climates over long open water summer cruises.
What duct size does this unit need?
Mermaid M9 requires a 4 inch duct ring size. This unified diameter metric allows the high-velocity centrifugal blower to exhaust immense cold air volume continuously, bypassing static friction traps inside tight bulkhead voids and providing efficient, uniform interior climate reduction throughout your small boat interior cabins.
Where should you install Mermaid M9?
Mermaid M9 is perfect for small guest staterooms and mid-cabins. Marine electronics experts typically mount this standalone 230 Volt system inside cockpit storage benches or beneath lower salon berths on performance boats up to thirty feet, keeping vital walking companionways clear of machinery obstructions during offshore voyages.
