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

The smallest condenser in CTM’s NMEA-free 230V split lineup, the CX-10H delivers 10,000 BTU of cooling and heating for boats that don’t need to step up to the 12,000 BTU class. One verified owner described it as “very powerful and quiet,” calling it a great product to replace an aging Cruisair system.

This dometic deu10 replacement condenser is sized specifically for smaller cabins or as a lightweight secondary zone, and at just 35 lbs it adds minimal weight and electrical load to an installation — a real advantage on boats where every pound of gear and every amp of reserve capacity has already been claimed elsewhere.

Why Choose the CTM CX-10H

A verified owner’s real-world review speaks to this unit’s quiet, powerful performance as a Cruisair replacement, and it’s backed by CTM’s standard 2-year warranty against material and workmanship defects. If you’re replacing a Dometic DEG10 or DEU10, dimensions and 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 due to the R22/R417A vs. R410A refrigerant difference
• Waterline connections use a standard 5/8″ fitting
