ACTA NOX

ACTA NOX is the range of Savio boilers designed to meet modern housing needs that require reliable, compact and high performance products. The ACTA NOX range includes open chamber boilers with power ratings of 24 kW and 28 kW .

The ACTA NOX series is suitable for heating and domestic hot water production. ACTA NOX has very compact dimensions which make it easy to place in any environment.

Characteristics:

• High yields
• Primary heat exchanger in copper, high circulation lamellar
• Sanitary plate heat exchanger in stainless steel
• Water cooled low NOx burner
• High efficiency pump with low energy consumption
• Integration with SAVIO solar systems using a solar kit
• Digital control panel with display.

The electronic card allows you to:

• Adjust the ignition pressure
• Adjust the restart frequency
• Manage the post-circulation of the high efficiency pump
• View fault diagnostics and lockout status.

Also available :

• Boiler antifreeze safety
• Primary circuit thermal inertia disposal.

Primary exchanger

ACTA NOX features a water-cooled burner which allows to achieve high efficiency combustion and to limit the emissions of polluting substances. The burner is therefore characterized by a flame at a lower temperature than traditional boilers, which reduces the production of nitrogen oxides.

Even the shape of the flame is specific to the water-cooled burner, in fact, it presents the flame in a uniform manner and with a reduced height.

This makes ACTA NOx the SAVIO product that satisfies the needs of maximum domestic comfort and respect for polluting emissions.

Secondary exchanger

ACTA NOX is available in a mixed version for heating, domestic hot water production: the hot water is supplied at an adjustable and constant temperature thanks to the electronic modulation of the boiler. The DHW exchanger is made of stainless steel and has a low inertia which guarantees excellent performance.

Control panel

• Summer/winter/off selector
• Heating temperature regulator
• DHW temperature regulator
• Digital and analog pressure reading
• DHW and heating temperature visualization from the display
• Display of fault diagnostics, block status and fault history
• Recommended fill display
• Display annual periodic maintenance expiry
• Thermo-hydrometer for reading the water pressure on the primary side.

Integration with solar

ACTA NOX can be easily combined with a solar system using the Biasi solar kit. Simple and immediate to install, it does not require electrical parts and allows optimizing the integration of the solar system with the boiler which intervenes only when necessary to guarantee the required comfort temperature.

Thermoregulation

Hydraulic groups of innovative conception:

• Motorized 3-way valve
• Integrated automatic by-pass: allows the boiler to adapt to the needs of modern heating systems
• Absolute heating pressure switch: guarantees protection of the boiler in the event of a lack of water or circulation
• Sanitary flowmeter
• Easily accessible filling tap
• Drain tap
