The motorized diverter valve series 6400 ensures flow to the generator in all conditions. In addition to diverting the fluid towards the heating system or the domestic hot water storage, this device features an integrated differential bypass function, which guarantees the minimum flow rate to the heat pump.

Key Features:

• Anti-dezincification alloy body – Suitable for heat pump systems with heating and cooling applications.
• Compact design – The minimal footprint makes it particularly ideal for the energy transition from boilers to heat pumps.
• High-capacity T-port diverter ball – Specifically designed for heat pump systems.
• Integrated adjustable differential bypass – Ensures the required auxiliary flow for heat pump operations, even in the absence of demand from the users.
• Preformed insulation and anti-condensation spacer – Provides complete protection against condensation issues and thermal dispersion.

This high-efficiency solution optimizes the operation of heat pumps, supporting the transition to more sustainable and energy-efficient systems.

Leading edge electronic mixing valve with thermal disinfection

LEGIOMIX®evo represents the evolution of Caleffi's electronic mixing valves and our technologically advanced solution to improve water system safety to protect water and people's health. No compromise has been made to deliver a safe, well-controlled performance of the various functions we have developed:

• Automatic thermal disinfection: the device regularly raises the mixed water temperature to lethal levels for bacteria to guarantee Legionella is eliminated safely and efficiently.
• Continual monitoring: thanks to the built-in sensors, it continually checks the hot water and return flow temperature, to ensure the parameters remain within safe limits.
• Remote operation and data logging: the Modbus/BACnet connectivity enables the system to be remotely controlled and optimised, whereas all data is recorded for analysis and legislative compliance.
• Recirculation pump management: the system is designed to time operations of the recirculation pump, in order to guarantee hot water is available on demand.

Equipped with an advanced digital regulator with a capacitive colour touchscreen LCD display, the device enables:

• All system functions to be managed directly via the display interface, with user-friendly operations;
• Personalised thermal disinfection programmes to combat Legionella;
• Real time monitoring of the hot water and return flow temperature;
• Disinfection parameters to be recorded and logged to ensure efficacy is checked continually;
• The system to be remotely controlled via Modbus and BACnet protocols and perfectly integrated with modern Building Management Systems (BMS)

Connectivity is the true strength of this model, revolutionizing the way operators can monitor and manage systems. Thanks to this innovation, LEGIOMIX®evo offers:

• Access to a cloud dashboard: thanks to the Ethernet connection, our solution is able to send data in real time to a remote dashboard. This allows operators to monitor and operate the device wherever they are, in order to improve the hot water system response rate and safety.
• Remote management and control: it is possible to program and monitor the device’s operation via a dedicated app, which will be available soon.

Automatic filling and demineralization unit consisting of:

• BA type compact automatic filling unit (art 580011 - DVGW);
• demineralisation cartridge with indicator resin;
• volume meter;
• shut-off valve and strainer;
• insulating shell;
• central heating system booklet.

The CALEFFI XF 577 series magnetic filter with extra filtering power allows unparalleled system cleaning. The combination of 3 different impurity separation functions ensures the optimal and continuous protection of the generator and the other devices in the system. On the other hand, its maintenance is easier thanks to the practical semi-automatic self-cleaning function.

Its special features:

• Integrate device: filter + dirt separator + magnetic effect

• Extra Filtering: large filtering surface with an extra fine mesh

• Semi-automatic cleaning: internal brush mechanism

• Consistent performance over time: large collection chamber outside the medium passage

• Versatile: installation on both horizontal and vertical pipes

We present our extra-level filter inside the CUBOROSSO, an interactive space where visitors can observe up close and experience firsthand the production steps and materials used in its creation. Here, you can explore the product’s features, designed to ensure continuous and long-lasting system protection, improving efficiency, reducing energy consumption, and lowering maintenance costs.

We invite you to discover our Solution, a tangible contribution to the energy transition process.

Electrolytic anti-scale device with filter and magnet

The electrolytic anti-scale device with filter and magnet, installed directly on the domestic cold water pipe, limits limescale formation within the domestic water system and the devices connected to
it. It also separates impurities in the system to a size of 50 μm. The magnet, suitably positioned in the flow, separates ferrous particles and helps to improve device efficiency.
