CTM CX-10HN – 10,000 BTU Condenser – Marine Split A/C Unit – 230V – 50/60HZ – R410A – NMEA 2000

The smallest condenser in CTM’s NMEA 2000 lineup, the CX-10HN delivers 10,000 BTU of split-system cooling and heating on 230V power — a direct drop-in replacement for the Dometic DEG10 and DEU10 condensing units, sized for smaller cabins or as a secondary zone on a larger vessel.

Why Choose the CTM CX-10HN

This is CTM’s entry point into split-system cooling, useful for smaller cabins that don’t need 12,000+ BTU of capacity, or as an additional zone paired with a larger primary system on bigger boats. At 3.2A cooling draw, it’s also the lightest electrical load in CTM’s split condenser lineup.

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 when 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 due to the R22/R417A vs. R410A refrigerant difference
• Waterline connections use a standard 5/8″ fitting
