CTM AH-6H Air Handler / Fan Coil – 6,000 BTU – 230V

Description

For boats without an NMEA 2000 backbone, or simply not needing network integration, the standard CTM AH-6H delivers the same 6,000 BTU cooling capacity as its NMEA sibling at a notably lower price point — $1,489 versus $2,209 for the AH-6HN, a difference that reflects the network hardware and Easycool display bundled into the networked version.

This is the entry point into CTM’s whole air handler range, and checking this listing’s own official spec PDF against the NMEA version confirms something useful: the “Refrigerant Type” and “Seawater Connection” terminology found across CTM’s AH-series isn’t something introduced for the NMEA product line specifically — it’s present on this standard, long-standing version too, suggesting it’s simply how CTM structures its air handler documentation across the board.

Key Features of the CTM AH-6H Air Handler

• Direct drop-in replacement for Dometic AU-HV air handlers, with waterline adapter included
• Reusable air filter — remove, rinse, and reinstall without replacement parts
• Vibration isolation base reduces noise transfer into the cabin
• Universal control board compatible with SMXir, Passport I/O, Smart Touch, and Elite II

CTM AH-6H Technical Specifications

These figures come from CTM’s official spec sheet (downloadable as a PDF directly from this listing). As noted above, several field labels here follow CTM’s standard air handler template rather than chilled-water-specific terminology — a pattern confirmed consistent across CTM’s whole AH-series rather than unique to this listing, though confirming the exact water connection type with CTM remains worthwhile for installation planning.

• Net Weight: 16.5 lbs

Why Choose the CTM AH-6H

At roughly $700 less than the NMEA-equipped AH-6HN, this is the practical choice for boats that don’t need MFD network integration for HVAC — same cooling capacity, same 2-year CTM warranty, without paying for connectivity hardware that would sit unused.

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
• A downloadable CTM AH spec sheet PDF is available directly from this product listing for further reference
