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

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.

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
