Description
For a 230V boat, a 12,000 BTU system can provide both cooling and heating for a salon or main cabin without moving into larger-yacht equipment requirements. The CTM CT-12H provides 12,000 BTU/h in both modes, 400 CFM airflow, and a six-inch duct connection. The supplied application guidance identifies salon and main-cabin installations on 30 to 40-foot vessels.
Key Features of CTM CT-12H
This self-contained 230V system combines reverse heating capacity, 400 CFM airflow, a digital touchpad, and a specified 5.5 GPM seawater-pump requirement for mid-size boats.
- Provides 12,000 BTU/h cooling for salons and main cabins.
- Adds 12,000 BTU/h heating for cooler seasonal boat use.
- Operates on compatible 230V, 50/60 Hz, single-phase power.
- Delivers 400 CFM through six-inch ducting for cabin airflow.
- Uses a 5.5 GPM pump for seawater heat exchange.
- Provides digital touchpad control for straightforward temperature adjustment.

CTM CT-12H Marine AC FAQ
What are the electrical requirements for CT-12H?
CTM CT-12H operates safely on a 230V power supply. This single-phase network installation draws minimal running current during standard cooling operations, enabling reliable climate management through your boat electrical distribution system without loading lower-voltage ship service lines unevenly or tripping main breakers.
What airflow volume does this system deliver?
CTM CT-12H generates an airflow volume of 347 CFM. The internal high-velocity centrifugal blower setup spins efficiently to ensure rapid, uniform cabin ventilation and temperature balancing while minimizing active component resonance over extended onboard journeys across open ocean cruise channels.
Which vessels fit the CTM CT-12H?
CTM CT-12H is designed for mid-sized cabins and crew quarters. It provides optimal cooling coverage for international sailboats and motor yachts ranging from thirty to thirty-eight feet, delivering efficient climate regulation underneath bunk spaces or within designated cockpit lockers without taking up crucial living space.
