Description
CTM AH-24HN NMEA 2000 Ready Chilled Water Marine Air Handler
Modern glass-bridge automation relies on specialized NMEA 2000 marine HVAC hardware like the CTM Marine AH-24HN, which provides 24,000 BTU/h of digital climate monitoring. Engineered specifically for zoned multi-cabin installations on 50ft+ cruising hulls, this network-ready fan coil delivers 650 CFM of conditioned air through an 8-inch outlet. The compact 285x600x285mm chassis layout and 14.6kg dry weight ensure a fast mechanical fit behind tight stateroom bulkheads while guaranteeing optimal gravity drainage for internal condensate pans.
Running safely off restricted onboard energy reserves, this high-efficiency system limits its active electrical footprint to a lean 0.9A and 140W load. Marine grade longevity is handled by a Blue-Fin aluminum evaporator coil that blocks galvanic pitting, while an integrated water control valve accommodates 5.5-6.5 GPM plumbing loops via 3/4″ MPT threads. Functioning smoothly across a 15-30°C climate range, this IP20-rated, CE-approved marine component protects your investment.
Key Features of CTM Marine AH-24HN:
- Certified smart digital data bus network integration
- Powerful 24,000 BTU/h climate regulation loop
- High-capacity 650 CFM constant air volume output
- Sustainable single phase 230V electrical machinery block
- Low draw 140W active power consumption rate
- Protective Blue-Fin anti-corrosive coil coating frame
- Built-in automatic water flow control valve setup
- Robust 14.6kg net housing frame layout configuration
- Isolates acoustic rumble below 54 dB(A) parameters
- Full CE marine safety certification structural design
Digital Network Climate Tracking
Smart NMEA 2000 automated bus data channels integrate this premium handler directly into your onboard environment. It communicates natively with modern marine electronics, allowing crew members to tweak zone temperatures using multi-function helm controllers. This advanced connectivity eliminates old analog control layout challenges, streamlining systemic diagnostic checks during standard maintenance windows.
Comprehensive System Protection Plan
Solid technical factory warranty backing protects this advanced network-ready air handler for a full two year window. This factory warranty guarantees that both the heavy-duty hydronic mechanical core and the NMEA 2000 data transceivers operate smoothly without failure. It minimizes financial risk for yacht owners executing complete marine HVAC system modernization overhauls.
Hull Matching Guidelines
Cruisers tracking 50 feet and above deliver an exact application use fitment for this 24,000 BTU/h network air handler. The 650 CFM constant air volume is dynamically balanced to satisfy the ventilation demands of large main cabin areas or combined pilot houses. It ensures consistent temperature management while fitting neatly into standard sub-cabinet yacht spaces.

CTM AH-24HN Air Handler FAQ
How much does CTM AH-24HN weigh?
CTM AH-24HN weighs exactly 34 lbs net weight. This high-capacity marine chiller fan coil unit provides 24,000 BTU of centralized cooling performance, optimizing climate parameters inside spacious boat interiors without adding structural weight. It features an embedded NMEA 2000 control board for seamless glass bridge integration.
What duct size does this unit need?
CTM AH-24HN requires a 7 inch duct ring size. This unified diameter specification allows the high-velocity centrifugal blower assembly to circulate large volumes of air smoothly, eliminating static backpressure stress within complex multi-outlet ventilation runs and ensuring rapid thermal reduction across your primary vessel living quarters.
Where should you install CTM AH-24HN?
CTM AH-24HN is perfect for expansive main salons and wide mid-ship master suites. Marine rigging yards typically secure this standalone 230 Volt system inside central utility lockers or beneath large booth dinettes on motor yachts up to fifty-five feet, regulating climate zones through integrated water flow control valves.
