D Series combines natural R290 refrigerant, inverter modulation, and high leaving-water temperature. It suits low-temperature systems and selected retrofit projects with radiator heating.
Key benefits
- Five variants from approximately 9 to 22 kW
- Leaving water up to 75 °C
- SCOP up to 4.98 at 35 °C leaving water
- Heating operation down to −25 °C ambient
Applications
- Heating and cooling of private homes
- Low-temperature radiators, underfloor heating, and fan coils
- Domestic hot water through a compatible tank
- Hybrid systems with solar generation and energy storage
Selection and integration
High-temperature projects must verify actual capacity and COP at the design condition. Retrofit design begins with heat-loss, hydraulics, and radiator assessment, and explores reducing water temperature to improve efficiency.
MICOE testing facilities
According to the MICOE catalogue, heat-pump development is supported by 46 specialized laboratories covering performance, reliability, acoustics, and low-temperature operation. Values in this card apply to the listed series models; the final duty point and configuration are confirmed during selection.
Specifications are based on the manufacturer's materials. For supply to Kazakhstan and the EAEU, required certificates, system scope, compatibility, and actual performance at the design condition are confirmed for the selected model and batch.
