CTM Marine AH-16H 16000 BTU Chiller Air Handler

At 458 CFM, the AH-16H is where CTM’s single-blower air handlers start moving noticeably more air than the mid-range models — a meaningful step up designed for larger salons or combined living spaces on bigger vessels. Blower speed also climbs to 1,420 RPM, the highest in the standard (non-24,000 BTU) range.

Boats retrofitting an aging Dometic or Cruisair air handler at this capacity should note the physical size increase that comes with it: at nearly 17 inches wide and just under 14 inches tall, this unit needs a real equipment bay, not the tight closet space that works for CTM’s 6,000 or 8,000 BTU models.

Why Choose the CTM AH-16H

This is the largest single-blower option in CTM’s standard (non-NMEA) range before stepping up to the dual-consideration AH-24H, backed by CTM’s standard 2-year warranty.

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
• Plan for a genuine equipment bay — this unit’s footprint is noticeably larger than CTM’s 6,000-12,000 BTU models
• If replacing a Dometic AU-HV air handler, waterline connections need adapting from 1/2″ to 3/4″ — adapter included
