Description
At the top of CTM’s NMEA fan coil range, the AH-24HN delivers 24,000 BTU with 776 CFM of airflow — over twice the capacity of the AH-12HN and enough to serve the largest single cabin or open-plan area most vessels have. This is the capacity tier where a central chiller system genuinely starts outperforming a collection of individual split units for whole-boat comfort.
Owners running multiple air handlers across different zones benefit most from NMEA integration at this scale: with a 24,000 BTU unit likely paired with several smaller handlers elsewhere on the boat, having all of them report status and accept commands through one MFD interface turns what could be a fragmented multi-zone HVAC setup into something that actually feels unified.
Key Features of the CTM AH-24HN 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)
- Real-time monitoring of inlet temperature and humidity
- Universal control board compatible with SMXir, Passport I/O, Smart Touch, and Elite II
CTM AH-24HN Technical Specifications
These figures come from CTM’s official spec sheet for this listing. Worth flagging separately here: the “Features” section on this specific page is still labeled for the AH-16H model rather than the AH-24H, a template artifact that’s easy to spot but doesn’t affect the specification numbers below, which are unique to this 24,000 BTU capacity.
- Capacity: 24,000 BTU
- Voltage: 208-240V
- Cycle: 50-60 Hz
- Blower Airflow: 776 CFM
- Blower Speed: 1,300 RPM
- Input Rotor Amps: 1.7 A
- Fuse Max: 5 A
- Blower Duct Size: 7″
- Dimensions (W x D x H): 20.8″ x 13.7″ x 17.5″
- Net Weight: 39 lbs
Why Choose the CTM AH-24HN
As the largest air handler in CTM’s NMEA lineup, this unit carries the same standard 2-year warranty as the rest of the range, with the NMEA Starter Kit and sensor included at purchase rather than sold separately.
What to Know Before Installing
- Do not assume the “Features” heading label on this listing reflects the correct model — the specifications table itself is accurate for the AH-24HN
- Confirm the exact water connection specifications with CTM, following the same pattern noted across CTM’s AH-series listings
- Requires a matching CTM CW-series chiller sized for this capacity as the central cooling source
- At 39 lbs and a 7″ duct, plan for a larger installation footprint than CTM’s smaller air handlers

CTM AH-24HN Air Handler FAQ
How much does CTM AH-24HN weigh?
CTM AH-24HN weighs exactly 34 lbs net weight. This high-capacity marine chiller fan coil unit provides 24,000 BTU of centralized cooling performance, optimizing climate parameters inside spacious boat interiors without adding structural weight. It features an embedded NMEA 2000 control board for seamless glass bridge integration.
What duct size does this unit need?
CTM AH-24HN requires a 7 inch duct ring size. This unified diameter specification allows the high-velocity centrifugal blower assembly to circulate large volumes of air smoothly, eliminating static backpressure stress within complex multi-outlet ventilation runs and ensuring rapid thermal reduction across your primary vessel living quarters.
Where should you install CTM AH-24HN?
CTM AH-24HN is perfect for expansive main salons and wide mid-ship master suites. Marine rigging yards typically secure this standalone 230 Volt system inside central utility lockers or beneath large booth dinettes on motor yachts up to fifty-five feet, regulating climate zones through integrated water flow control valves.
