CTM Marine CX-12HN 12000 BTU NMEA 2000 Condenser 230V

For boats standardized on 230V power, the CTM CX-12HN condenser delivers 12,000 BTU of split-system cooling and reverse cycle heating — purpose-built as a drop-in replacement for the Dometic DEU12 and DEG12 units, with the titanium coil construction and NMEA 2000 integration found across CTM’s condenser lineup.

Why Choose the CTM CX-12HN

If you’re replacing a Dometic DEU12 or DEG12, this unit is built to match those units’ dimensions and waterline connections closely enough that installation typically doesn’t require significant modification — though double-checking your specific installation space against the CX-12HN’s specs before ordering is still worth the few minutes it takes.

Being a condenser-only unit, this pairs with a separately purchased evaporator installed in the cabin space, connected via insulated refrigerant lines — standard for split systems, and the reason they run quieter in the living area than self-contained units.

What to Know Before Installing

• EPA certification must be provided before shipping
• Requires a separately purchased evaporator — this listing is the condenser only
• If replacing a Cruisair RX unit, the evaporator will also need replacing since RX systems use R22/R417A refrigerant, not R410A
• Waterline connections use a standard 5/8″ fitting
