Sunex Hydra Tower PRO - complete boiler room solution in one device - domestic hot water tank 210l with two heat exchangers + buffer tank 65l

Complete boiler room equipment in one single unit

Maximum compatibility of components

Compatibility with Nexus M EVI and Nexus M PRO heat pumps

The HYDRA TOWER is characterized by its compact design, which allows for optimal use of space. With a footprint of just over 1 m², the HYDRA TOWER's small installation area reduces costs for new buildings and creates additional space in existing buildings.

By housing the domestic hot water and buffer tanks, circulation pumps, three-way valve, filter, and fittings in one compact casing, the HYDRA TOWER ensures an aesthetic appearance in the boiler room. The integrated control system enables the heat pump and other heating components to be controlled.

Features and Benefits

Compact Design: The unit requires a footprint of just over 1 m², saving space in the boiler room and potentially reducing construction costs for new buildings.

Integrated Components: The HYDRA TOWER houses essential components such as domestic hot water tank, buffer tank, circulation pumps, three-way valve, filter, and fittings in a single casing.

Aesthetic Appearance: By housing all components in a compact casing, it provides a tidy and aesthetic appearance in the boiler room.

Control: An implemented control system enables the heat pump and the entire boiler room equipment to be controlled. Control via the internet is also possible.

Efficiency: The system is designed for high operating efficiency and a long service life, partly through the use of components from recognized global manufacturers.

Expandability: Expansion kits are available to integrate, for example, a second heating circuit into the system.
