CTM Marine CX-12 12000 BTU Split A/C Condenser 115V

Standard 115V shore power gets the same 12,000 BTU capacity with the CTM CX-12 condenser — a direct drop-in replacement for the Dometic DEG12 and 220V DEU12 condensing units, without the added cost of soft start technology most boats on a properly sized 115V circuit don’t need. This compact marine ac condenser 115v unit fits the same footprint as its 230V counterpart, making it a straightforward fit for boats already laid out around CTM’s standard dimensions.

Choosing the standard 115V version over a soft-start unit is a simple cost decision for boats with adequate breaker capacity — you get identical cooling and heating output and identical titanium coil construction, just without paying for a feature your electrical panel doesn’t require. That makes it the more economical path for most standard-voltage installs in this capacity range.

Why Choose the CTM CX-12 (115V)

This is the standard-voltage entry point into CTM’s 12,000 BTU split lineup, backed by CTM’s standard 2-year warranty against material and workmanship defects. If you’re replacing a Dometic DEG12 or 220V DEU12, dimensions and waterline connections match closely enough for a straightforward swap.

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
