CTM AH-24H – Air Handler / Fan Coil 24,000 BTU Flow Control Valve – 230V – 50/60HZ

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.

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
