CTM AH-16HN Air Handler / Fan Coil – 16,000 BTU – 230V – NMEA 2000

The CTM AH-16HN steps up to 16,000 BTU for boats running NMEA 2000 networks and needing to cool a genuinely large cabin or open salon area from the central chiller. Blower airflow jumps to 458 CFM here — a meaningful step up from the 12,000 BTU model’s 347 CFM, reflecting the larger room volumes this size is built to serve.

Boats retrofitting from an older Dometic AU-HV system while also upgrading their electronics find a natural pairing point here: swapping in NMEA-networked air handlers during a chiller refresh means the HVAC data starts flowing to the same MFDs already handling navigation, without a second retrofit project down the line.

Why Choose the CTM AH-16HN

This unit ships with the NMEA Starter Kit and Easycool display already bundled in, and carries CTM’s standard 2-year warranty — coverage that matters more at this price point than on the smaller capacity models in the range.

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
• The larger 6″ blower duct on this model may require reworking ductwork sized for a smaller previous unit
