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

Description

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.

Key Features of the CTM CX-12 Condenser (115V)

This 12000 btu split condenser 115v unit is built on CTM’s standard titanium-coil platform, sized for smaller-to-midsize vessels or as a secondary zone on a larger boat. The features below match CTM’s broader condenser lineup at this capacity.

• Direct drop-in replacement for Dometic DEG12 (115V) and DEU12 (220V) condensing units
• Titanium condenser coils resist corrosion significantly better than copper in seawater applications
• Universal control board compatible with SMXir, Passport I/O, Smart Touch, and Elite II controllers
• Compact 35 lb unit fits tighter engine room installations than larger CTM condensers
• Rugged electrical box with a fire-retardant cover for added safety

CTM CX-12 Technical Specifications (115V)

These figures come from CTM’s official spec sheet for the 115V configuration. Current draw runs roughly double the 230V CX-12H’s, which tracks with the voltage difference and is worth factoring into your electrical panel planning.

• Capacity: 12,000 BTU
• Voltage: 100-120V
• Cycle: 50-60 Hz
• Refrigerant: R410A
• Current Consumption (Cool/Heat): 6.5 A / 8.5 A
• Starting Amps: 22 A
• Locked Rotor Amps: 42 A
• Fuse Max/Min: 25 A / 16 A
• Seawater Inlet: 5/8″
• Suggested Water Flow: 250 GPH
• Dimensions (W x H x D): 8.67″ x 13.5″ x 13.5″
• Net Weight: 35 lbs

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
