21,000 BTU Three-Zone Multi-Split Outdoor Unit (A+++ Energy Class, R32 Inverter Heat Pump)

Key Features & Comprehensive Product Overview

Supreme Energy Efficiency Tailored for European Standards

Engineered specifically to fulfill the stringent energy performance benchmarks across the European Union, this 21,000 BTU Multi-Split DC Inverter Heat Pump outdoor unit provides exceptional cooling and heating performance. Powered by an advanced SANYO Rotary Inverter Compressor, the system achieves an outstanding Seasonal Energy Efficiency Ratio (SEER) of 8.5, qualifying for the top-tier A+++ energy rating under EU ERP eco-design regulations. In heating mode, it delivers a Seasonal Coefficient of Performance (SCOP) reaching up to 5.4 in warm zones and 4.6 in average climate conditions. This remarkable efficiency allows European homeowners and business operators to significantly lower their annual electricity bills while reducing overall carbon emissions.

Independent Three-Zone Climate Control & Versatile Indoor Compatibility

Designed as a three-zone outdoor chassis, this multi-split solution allows the connection of up to three separate indoor units to a single, compact outdoor condenser. Each connected zone operates independently via dedicated Electronic Expansion Valves (EEV) that precisely meter refrigerant flow according to individual room demands. Whether configuring wall-mounted units, slim ducted systems, or ceiling cassettes in residential apartments, modern townhouses, or light commercial offices, the system guarantees customized comfort in each room without wasting energy on unoccupied spaces.

Advanced All-Weather Heat Pump Performance

Equipped with extended low-ambient operation technology, this dual-zone heat pump system guarantees year-round indoor thermal comfort across diverse European geographical landscapes. During scorching summer heatwaves, it maintains reliable cooling performance in ambient temperatures up to +53°C. In frigid winter conditions, the system operates effectively down to -25°C ambient heating, serving as a dependable, energy-efficient alternative or supplement to traditional gas boilers and electric resistance heaters. The intelligent auto-defrost mechanism prevents ice build-up on the outdoor heat exchanger coil, ensuring continuous heating efficiency during damp, freezing days.

Eco-Friendly R32 Refrigerant & Decarbonization Alignment

In line with EU F-Gas regulations and environmental sustainability targets, this multi-split outdoor unit uses high-performance, eco-friendly R32 refrigerant. Featuring a Global Warming Potential (GWP) of only 675—a 68% reduction compared to legacy R410A systems—and requiring a lower charge volume (1.2 kg), it delivers superior thermodynamic heat transfer efficiency while dramatically minimizing environmental impact. Adopting R32 heat pump technology directly supports Europe’s transition toward zero-emission building heating and sustainable home modernization.

Whisper-Quiet Acoustic Performance for Residential Neighborhoods

Noise control is a critical factor for suburban and multi-family residential installations across Europe. Utilizing an aerodynamic DC fan motor, optimized axial fan blades, and a sound-insulated compressor jacket, the outdoor unit operates at a low sound pressure level of just 61 dB(A). This ultra-quiet acoustic profile minimizes outdoor noise pollution, ensuring full compliance with local municipal noise guidelines in densely populated residential areas and apartment balconies.

Why Upgrade to an A+++ Multi-Split Heat Pump System?

• Drastic Reduction in Heating & Cooling Expenses: With conventional energy costs fluctuating across Europe, moving to an A+++ rated DC Inverter heat pump system provides direct financial benefits. By capturing heat from the outside air rather than generating heat from fuel combustion, the unit delivers up to 5.8 kW of heating energy for every 1 kW of electricity consumed, yielding substantial lifetime savings.
• Space-Saving Architecture for Modern Homes: Installing multiple single-split outdoor units on walls or balconies often compromises building aesthetics and consumes valuable exterior space. A multi-split outdoor condenser consolidates outdoor footprints into a single sleek unit (913 × 699 × 375 mm), preserving architectural design while simplifying exterior wiring and refrigerant piping layouts.
• Ideal Retrofit Solution for Boilers & Single Rooms: Whether replacing old, inefficient single-stage air conditioners or retrofitting traditional fossil-fuel heating systems, this 21K BTU unit offers a future-proof, flexible upgrade path. Its multi-room capabilities allow step-by-step room climate management, providing an ideal heat pump solution for renovations and new building developments alike.

Installation & System Reliability Guidelines

Flexible Piping & Long-Distance Capabilities: To accommodate complex architectural layouts, the outdoor chassis supports a maximum total refrigerant piping length of up to 60 meters, with a maximum single indoor unit line length of 25 meters and a height elevation differential of up to 15 meters. The unit comes factory pre-charged with R32 refrigerant suitable for up to 10 meters of total pipe run, making on-site commissioning quick, straightforward, and cost-effective for HVAC installers.

Heavy-Duty Anti-Corrosion Construction: Built to endure harsh outdoor elements—from salty coastal breezes to heavy winter precipitation—the outdoor enclosure is coated with multi-layer anti-corrosion galvanized steel. The internal heat exchanger coil features specialized protective fins that resist oxidation, ensuring long-term thermal efficiency and prolonging overall equipment service life.
