Description
For boats standardized on 230V power, the CTM CX-16HN condenser delivers 16,000 BTU of split-system cooling and heating, purpose-built as a drop-in replacement for the Dometic DEU16 and DEG16 units it was designed to match dimensionally and electrically.
Key Features of the CTM CX-16HN Condenser
- Direct drop-in replacement for Dometic DEU16 (230V and 220V) and DEG16 (230V) condensing units
- NMEA 2000 integration enables embedded HVAC control through compatible MFD systems
- Titanium condenser coils outperform copper for long-term corrosion resistance in seawater
- Universal control board works with existing SMXir, Passport I/O, Smart Touch, and Elite II controllers
- Compact 42 lb unit suited for tighter engine room installations on smaller-to-midsize vessels

Why Choose the CTM CX-16HN
If you’re replacing a Dometic DEU16 or DEG16, this unit is built to match those units’ dimensions and waterline connections closely enough that installation shouldn’t require significant modification — though double-checking your specific installation space against the CX-16HN’s specs before ordering is still worth the few minutes it takes.
Being a condenser-only unit, this pairs with a separately purchased evaporator in the cabin space; the CX and EV units share the same R410A refrigerant, so no evaporator swap is needed if you’re only replacing a failed condenser on an existing CTM split system.
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

CTM CX-16HN Split Condenser FAQ
What are the electrical requirements for CX-16HN?
CTM CX-16HN operates safely on a 208-230V power supply. This single-phase network installation draws minimal running current during standard cooling operations, enabling reliable climate management through your boat electrical distribution system without loading lower-voltage ship service lines unevenly or tripping main breakers.
What are the physical dimensions of CX-16HN?
CTM CX-16HN features a footprint of 20x12x13.25 inches. These tight dimensional limits facilitate easy drop-in mounting behind salon bulkheads or inside cockpit storage lockers, presenting an efficient installation alternative for vessel retrofits when older, bulkier mechanical climate hardware setups are being updated or replaced entirely.
When is the CTM CX-16HN best applied?
CTM CX-16HN is best applied as a primary climate controller for offshore sportfishers. The system handles main salons or large master staterooms on vessels from thirty-four to forty-two feet, utilizing its smart NMEA 2000 communication protocol to interface with modern glass bridge multi-function helm screens.
