MB2-230SN3-L 3-way valve, 230V, left

The HyBo (Hydraulic Interface Unit) is a hydraulic interface installed in multi-family dwellings between the centralized systems and each flat. It allows combining the efficiency of a centralized boiler with the benefits of individual control and metering.

The heating systems where the MB2 can guarantee the best performances are designed basing on variable flow characteristics, with high differential tamperatures and low return temperatures:

• High Delta-T conditions, allow minimizing nominal water flow and a more flexible distribution system.
• With minimized flow it is possible to contain pipeline dimensions, reducing costs and simplifying installation.
• A low flow system allows reduction of the pump size. Also electricity consumption is reduced when pipelines are designed for reducing total system pressure drop.
• A low flow system combined with low pressure drop pipelines facilitate balancing due to low pressure drop from the main risers of the plant.
• Low return temperature conditions guarantee best performance for generation system such as condensing boiler, district heating system, heat pump systems, etc.
• High Delta-T allow to reduce the measures errors of meters (ref EN1434, UNI10200).
• MB2 units are also available for constant flow systems applications.

MB2, main functions:

• Heating: hydraulic interface between main rise and flat with high temperature output, balancing, metering, on/off control from room thermostat.

MB2 Advantages:

• Simple and very compact unit to manage from a single point of entry the opening and closing of apartment heating circuit, balancing and individual metering.
• Flexibility of equipments: several types of heatmeters, watermeters and balancing combinations.
• Possibility to upgrade to automatic balancing also after the installation.
