Energy Efficiency A (SCOP)
Superior energy savings with A-rated performance. Optimizes heat output across seasons to lower electricity bills and reduce your carbon footprint.
R32 Refrigerant
Eco-friendly coolant with a lower Global Warming Potential. Delivers superior heat transfer for powerful performance while protecting the planet.
3D Inverter Technology
Ultimate comfort, zero fluctuations. Rapidly reaches desired temperatures with quiet, precise control for faster cooling, heating, and lasting durability.
ULTRA ENERGY SAVING
Driven by Nancent's advanced 3D full inverter technology, the OCEAN CONCH SERIES optimists the operation of the compressor, fan, and EEV to achieve faster heating. Compressor insulation and corrosion-resistant titanium heat exchanger ensure long-lasting efficiency and steady water temperature.

INTELLIGENT CONTROL
3 Temperature Control Modes
Heating Mode
When the inlet water temperature is lower than the heating target temperature, the unit will activate the heating mode.
Cooling Mode
When the inlet water temperature exceeds the cooling target temperature, the unit will activate the cooling mode.
Auto Mode
If the inlet water temperature is lower than the auto target temperature, the unit will operate in heating mode. If the inlet water temperature is higher than the auto target temperature, the unit will operate in cooling mode.
3 Running Modes
Smart Mode
Energy saving is achieved by operating at a comfortable frequency in Smart Mode.
Powerful Mode
Rapid heating is achieved by operating at a high frequency in Powerful Mode.
Silent Mode
A quiet environment is provided by operating at a low frequency in Silent Mode.

ULTRA-SILENT EXPERIENCE
Single-Layer Compressor Insulation
A high-density acoustic foam layer envelops the compressor, efficiently absorbing operational vibrations and blocking mechanical noise transmission from the source.
Anti-Vibration System
The suspended mounting structure isolates mechanical vibrations from the chassis, ensuring exceptionally smooth, quiet, and stable performance.
Streamlined Fan Blade Design
Aerodynamically optimized serrated-edge blades improve airflow efficiency while minimizing turbulence and air movement noise.
Sturdy 1.2mm Frame
The reinforced 1.2mm-thick chassis and motor support bracket provide superior rigidity, minimizing resonance and vibration for long-term silent stability.
Silent Mode
The intelligent silent mode automatically adjusts fan speed and compressor frequency to maintain desired comfort levels while creating a calm and peaceful environment anytime.
SG & HEMS CONNECTIVITY
SG Ready
The OCEAN CONCH SERIES provides a connection to the smart grid to enable automated operation based on dynamic electricity prices. This ensures the unit works most efficiently when power is cheapest, delivering optimal 24/7 cost savings.
HEMS Ready
Achieve full energy synergy by connecting the OCEAN CONCH SERIES heat pump to the PV and battery systems with a Home Energy Manager/Smart Meter.
Nancent's self-developed HEMS platform empowers you to maximize green energy usage, taking control of your home's energy efficiency and sustainability.
