Highly effective, modern Nexus Split EVI
Heat pumps
Domestic water and central heating heat pumps
Heat pumps for central heating and hot water preparation
inverter-split heat pumps
The heat pumps are equipped with a continuously variable compressor and a brushless fan with variable speed control. This allows the heat pump to be adapted to the energy requirements of the heat consumers. The stable operation of the heat pump enables high efficiency while maintaining a low noise level generated by the compressor. The cooling system equipped with EVI technology (Enhanced Vapour Injection) ensures high efficiency in classic cooling installations. The high quality of the device is guaranteed by innovative solutions based on components from well-known global manufacturers such as Panasonic, Grundfos and Carel.
- One of the cheapest ways to heat buildings. The system works even at temperatures of -20°C
- High efficiency and long service life thanks to the use of components from world-renowned manufacturers
- A comprehensive control system ensures optimal control and security of the system. Control via the Internet is possible. A wired control panel is included as standard
- High ease of use. Intuitive and easy operation of the control
- The split design eliminates the risk of pipe freezing during power outages
- Energy class A++ at 55°C flow temperature, A+++ at 35°C flow temperature
- Quiet operation
