CTM AH-8H – Air Handler / Fan Coil 8,000 BTU Flow Control Valve – 230V – 50/60HZ

Description

CTM’s entry into serious chiller-fed cooling starts meaningfully at the AH-8H, an 8,000 BTU fan coil built as a direct swap for the Dometic AU-HV air handler. Unlike the smaller 6,000 BTU model, this size handles a proper single-cabin cooling load without needing to run at full blower speed constantly to keep pace.

One detail worth knowing before ordering: CTM groups its blower assemblies in capacity pairs rather than one-per-model — the AH-8H shares its blower hardware with the 6,000 BTU AH-6H, both drawing from the same 6K-8K BTU parts catalog listing. That’s useful to know if you’re ever sourcing a replacement blower down the line, since the part will be labeled for the pair, not just this specific model.

Key Features of the CTM AH-8H Air Handler

• Reusable air filter — remove, rinse, and reinstall without replacement parts
• Vibration isolation base under the blower reduces cabin noise
• Stainless steel structural pan resists corrosion in marine environments
• Universal control board compatible with SMXir, Passport I/O, Smart Touch, and Elite II

CTM AH-8H Technical Specifications

These figures come from CTM’s published spec sheet for this listing. As with CTM’s broader air handler range, some field terminology (refrigerant type, seawater connection) follows CTM’s standard documentation template rather than chilled-water-specific language — worth confirming the actual water connection type with CTM before finalizing an installation plan.

• Voltage: 208-240V
• Cycle: 50-60 Hz
• Blower Airflow: 350 CFM
• Blower Speed: 1,200 RPM
• Input Rotor Amps: 0.7 A
• Fuse Max: 5 A
• Blower Duct Size: 5″
• Dimensions (W x D x H): 16.1″ x 10.7″ x 12.1″
• Net Weight: 22 lbs

Why Choose the CTM AH-8H

Backed by CTM’s standard 2-year warranty, this is a straightforward, no-frills option for boats that don’t need NMEA network integration — same cooling performance as the AH-8HN at a lower price point, without the bundled display hardware.

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
• Shares its blower assembly part number with the 6,000 BTU AH-6H for future service parts
