CLIMATE BOAT / MARINE AIR CONDITIONERS
Dometic DCU Self-contained High-capacity Compact A/C
Engineered to harness and maximize the impressive performance of environmentally safe R410A refrigerant. These units offer direct expansion operation in a compact, low-profile unit with a seawater-cooled condenser and choice of controls. Compact design • High-velocity fully insulated blowers are rotatable • Patented design increases cooling capacity and dehumidification • Condenser coil’s cupronickel-encased copper coil provides maximum heat transfer and high resistance to corrosion • Evaporator coil employs an enhanced fin design and rifled copper tubing to provide maximum capacity

1. To complete the model numbers for a specific voltage/cycle/phase, add a ‘-1161’ for 115V/60Hz/1-Phase, or ‘-2361’ for 230V/60Hz/1-Phase, followed by ‘-410A’ (e.g. ‘DCU27-2361-410A’). 2. TU and electrical data are based on a 45°F/7.2°C evaporator and 100°F/37.8°C condenser in cool mode, and a 45°F/7.2°C evaporator and 130°F/54.4°C condenser in heat mode. 3. 60Hz units must not operate at 50 Hz and 50 Hz units must not operate at 60Hz unless data plate states otherwise 4. All dimensions ± 0.30 in/8 mm. 5. All weights ± 10%.
