Heat pump monoblock air water nexus m 18 kW

Heat pump Nexus M EVI 18 kW

Monoblock inverter technology

The Nexus M EVI heat pump features a continuously variable inverter compressor and a brushless fan with variable speed. This allows the performance to precisely match the actual energy demand, ensuring maximum efficiency for both heating and hot water production. Thanks to its quiet operation, the sound power level remains pleasantly low, even at full capacity.

EVI refrigeration system for maximum efficiency

Thanks to Enhanced Vapor Injection (EVI) technology, the cooling system achieves outstanding performance even at low outside temperatures. Conventional radiator systems and underfloor heating systems benefit from the high flow temperatures. Efficiency remains stable even at -25°C, making the Nexus M EVI the ideal choice for regions with cold winters.

Advantages of the compact monoblock design

The entire cooling system is housed in a single unit that can be installed outdoors. Only the water pipes need to be routed inside the building. This design reduces installation effort, minimizes leakage risks, and makes the heat pump particularly easy to service. The compact dimensions of 1050 × 480 × 1330 mm allow for space-saving installation outdoors.

Intuitive control and networking options

An integrated touch display ensures easy operation and clear control of all system parameters. Comprehensive safety features protect against frost, overheating, and power fluctuations. If necessary, the heat pump can be integrated into smart home systems via an internet connection and monitored remotely.

Performance data and technical specifications

The Nexus M18 EVI achieves a SCOP of 4.46 (W35) and 3.51 (W55) in temperate climates, thus falling within energy efficiency class A+++ at a flow temperature of 35°C and A++ at a flow temperature of 55°C. Equipped with a high-quality Panasonic compressor, electronic expansion valve, and two variable speed fans, it delivers up to 7.15 A of hot water output. The environmentally friendly refrigerant R32 with a GWP of 675 ensures a sustainable heat supply.

Robust operation under extreme conditions

Whether Siberian frost or hot summer days – the Nexus M EVI operates reliably at outside temperatures ranging from -25°C to +45°C. A defrost cycle using hot gas reversal keeps the system ice-free even in winter. High-quality components from world-renowned manufacturers guarantee a long service life and low-maintenance operation.
