CTM AH-6HN Air Handler / Fan Coil – 6,000 BTU – 230V – NMEA 2000

Boats running NMEA 2000 networks and wanting 6,000 BTU of central chiller cooling with full MFD integration have an option in the CTM AH-6HN Air Handler, which adds NMEA 2000 connectivity to CTM’s fan coil lineup for control through Garmin Empirbus, OneHelm, and Raymarine YachtSense-compatible displays.

The real advantage of NMEA integration here is consolidation: instead of a dedicated HVAC display taking up panel space, this unit’s status and controls become another data source on the boat’s existing chartplotter or MFD network, alongside the included Easycool 3.5″ touchscreen for standalone control when needed.

Why Choose the CTM AH-6HN

This unit carries CTM’s standard 2-year warranty against material and workmanship defects. Given the significant specification discrepancies identified above, confirming the actual chilled water connection size, minimum flow rate, and other installation-critical specs directly with CTM before ordering is strongly recommended — not just a formality.

What to Know Before Installing

• Confirm actual chilled water connection specifications directly with CTM given the discrepancies 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
• NMEA 2000 Starter Kit and temperature/humidity sensor are included with this unit
