Description
The CTM AH-16HN steps up to 16,000 BTU for boats running NMEA 2000 networks and needing to cool a genuinely large cabin or open salon area from the central chiller. Blower airflow jumps to 458 CFM here — a meaningful step up from the 12,000 BTU model’s 347 CFM, reflecting the larger room volumes this size is built to serve.
Boats retrofitting from an older Dometic AU-HV system while also upgrading their electronics find a natural pairing point here: swapping in NMEA-networked air handlers during a chiller refresh means the HVAC data starts flowing to the same MFDs already handling navigation, without a second retrofit project down the line.
Key Features of the CTM AH-16HN Air Handler
- NMEA 2000 connectivity for control through Garmin Empirbus, OneHelm, and Raymarine YachtSense
- Includes Easycool 3.5″ NMEA 2000 touchscreen display (or Easycool Mini 2.4″ with Vimar bezel)
- Bluetooth and Wi-Fi connectivity for remote monitoring via companion Apple or Android apps
- Universal control board compatible with SMXir, Passport I/O, Smart Touch, and Elite II
CTM AH-16HN Technical Specifications
These figures come from CTM’s official spec sheet for this listing. As with the rest of CTM’s AH-series, some field labels here (refrigerant type, seawater connection) follow CTM’s standard air handler template rather than chilled-water-specific terminology — worth confirming the exact connection type directly with CTM if you’re matching this to a specific chiller installation.

- Voltage: 208-240V
- Cycle: 50-60 Hz
- Blower Airflow: 458 CFM
- Blower Speed: 1,420 RPM
- Input Rotor Amps: 0.9 A
- Fuse Max: 5 A
- Blower Duct Size: 6″
- Dimensions (W x D x H): 16.9″ x 11.6″ x 13.8″
- Net Weight: 28 lbs
Why Choose the CTM AH-16HN
This unit ships with the NMEA Starter Kit and Easycool display already bundled in, and carries CTM’s standard 2-year warranty — coverage that matters more at this price point than on the smaller capacity models in the range.
What to Know Before Installing
- Confirm the exact water connection specifications with CTM given the terminology noted above
- Requires a matching CTM CW-series chiller as the central cooling source
- If replacing a Dometic AU-HV air handler, waterline connections need adapting from 1/2″ to 3/4″ — adapter included
- The larger 6″ blower duct on this model may require reworking ductwork sized for a smaller previous unit

CTM AH-16HN Air Handler FAQ
How much does CTM AH-16HN weigh?
CTM AH-16HN weighs exactly 28 lbs net weight. This high-capacity split system air handler supplies 16,000 BTU of cooling power, allowing vessel refitters to execute multi-outlet ducting runs without loading excessive structural weight down onto cabin bulkheads or beneath bunk layout boundaries on modern luxury powerboats.
What duct size does this unit need?
CTM AH-16HN requires a 6 inch duct ring size. This factory specification authorizes the integrated high-velocity centrifugal blower assembly to discharge air freely, neutralizing static backpressure limitations inside narrow companionway compartments and establishing rapid, balanced environmental temperature drops across boat living facilities.
Where should you install CTM AH-16HN?
CTM AH-16HN is perfect for large multi-stateroom layouts and spacious motor yacht bridge salons. Marine rigging specialists typically bolt down this standalone 230 Volt system inside central companionway spaces or beneath major galley benches on hulls up to forty-eight feet, optimizing overall cabin air distribution pathways through the ship backbone.
