Description
The AH-24H tops out CTM’s standard air handler lineup at 24,000 BTU and 776 CFM — more than double the airflow of the AH-12H, sized for the largest single zones a boat is likely to need cooled from one unit. This is genuinely different equipment from the smaller models, not just a scaled-up version.
At 39 lbs and requiring a 7-inch duct, installation planning matters more here than on CTM’s smaller handlers — this isn’t a unit that tucks into a spare locker easily, and the ductwork run needs to be sized for real airflow volume from day one rather than retrofitted later.
Key Features of the CTM AH-24H Air Handler
- Largest single unit in CTM’s standard air handler range at 24,000 BTU
- Universal control board compatible with SMXir, Passport I/O, Smart Touch, and Elite II
- Reusable air filter for ongoing maintenance without replacement parts
CTM AH-24H Technical Specifications
These figures come from CTM’s published spec sheet for this listing, matching the AH-24HN’s data exactly. One thing worth flagging separately from the recurring terminology pattern across CTM’s range: this specific listing’s “Features” section heading is still labeled for the AH-16H rather than the AH-24H — a template artifact that doesn’t affect the specification numbers below.
- 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-24H
As the largest handler in CTM’s standard range, this unit carries the same 2-year warranty as the rest of the lineup, at a lower price than the NMEA-equipped AH-24HN for boats that don’t need MFD network integration.
What to Know Before Installing
- Do not assume the “Features” heading on this listing reflects the correct model — the specifications table itself is accurate for the AH-24H
- Confirm the exact water connection specifications with CTM given the terminology pattern noted across CTM’s AH-series
- Requires a matching CTM CW-series chiller sized appropriately as the central cooling source
- Budget real installation space — this is CTM’s largest and heaviest standard air handler

CTM AH-24H Air Handler FAQ
What are the electrical requirements for AH-24H?
CTM AH-24H operates safely on a 230V power connection. This localized single-phase air handler installation draws minimal running current, enabling vessel owners to run targeted cabin ventilation smoothly off standard dock shore lines or small marine generator panels without creating unbalanced electrical loads across the ship distribution system.
What airflow volume does this system deliver?
CTM AH-24H generates an airflow volume of 550 CFM. The integrated high-velocity centrifugal blower fan moves conditioned air efficiently across your accommodation layout, accelerating interior dehumidification while maintaining a whisper-quiet acoustic profile that prevents sleep disruption during overnight anchorages in remote coastal coves.
Which vessels fit the CTM AH-24H?
CTM AH-24H is designed for expansive yacht main bridge salons and multi-deck lounging areas. It serves as an ideal high-capacity companion for recreational watercraft and sailing vessels from forty-five to fifty-five feet, utilizing its factory-installed electronic water flow control valve for multi-stateroom temperature regulation precision.
