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

Description

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.

Key Features of the CTM AH-6HN Air Handler

This ctm nmea 2000 fan coil unit brings full MFD network integration to CTM’s smallest air handler capacity, letting HVAC status and control live on the same displays as the rest of the boat’s electronics.

• NMEA 2000 connectivity for control through Garmin Empirbus, OneHelm, and Raymarine YachtSense
• Includes Easycool 3.5″ NMEA 2000 touchscreen display (or Easycool Mini 2.4″ with Vimar bezel)
• Bluetooth and Wi-Fi connectivity for remote monitoring via companion Apple or Android apps
• Real-time monitoring of inlet temperature and humidity
• Universal control board compatible with SMXir, Passport I/O, Smart Touch, and Elite II

CTM AH-6HN Technical Specifications

These figures come from CTM’s official spec sheet for this listing — but a significant transparency note is required here: the specification table and body copy on this page appear to describe a self-contained or condensing unit rather than a chilled-water air handler, referencing “Refrigerant Type,” “Locked Rotor Amps,” and “Seawater Inlet/Outlet Connection” rather than the chilled water connection specs an air handler of this type would normally carry. The page’s own body text even states CTM “created a split marine condensing unit,” which doesn’t match this product category. These figures should be confirmed directly with CTM before relying on them for installation planning.

• Net Weight: 16.5 lbs
• Note: additional fields on this listing (refrigerant type, locked rotor amps, seawater connections) appear to be copied from a different product category and are not included here — confirm actual chilled water connection specs with CTM directly

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
