Savio ACTA NOX 28A LPG Open Chamber Gas Boiler

ACTA NOX is the Savio boiler range designed to meet modern living needs that require reliable, compact, and high-performance products. The ACTA NOX range includes open-flue boilers with power outputs 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, making it easy to place in any environment.

Characteristics:

• High yields
• Primary copper exchanger, lamellar, high circulation
• Stainless steel plate heat exchanger
• 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 board allows you to:

• Adjust the ignition pressure
• Adjust the re-ignition frequency
• Managing the post-circulation of the high-efficiency pump
• View fault diagnostics and lock status.

Also available :

• Boiler antifreeze safety
• Disposal of thermal inertia in the primary circuit.

Primary exchanger

ACTA NOX features a water-cooled burner that achieves high-efficiency combustion and limits pollutant emissions. The burner therefore features a lower flame temperature than traditional boilers, reducing the production of nitrogen oxides.

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

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

Secondary exchanger

ACTA NOX is available in a combined version for heating and domestic hot water production: hot water is delivered at an adjustable and constant temperature thanks to the boiler's electronic modulation. The domestic hot water exchanger is made of stainless steel and has low inertia, ensuring excellent performance.

Control panel

• Summer/winter/off selector
• Heating temperature regulator
• Sanitary temperature regulator
• Digital and analog pressure reading
• Display of domestic hot water and heating temperature
• Display fault diagnostics, block status and fault history
• Recommended Fill View
• Viewing annual periodic maintenance deadline
• Thermohydrometer 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. Quick and easy to install, it requires no electrical components and optimizes the integration of the solar system with the boiler, which only activates when necessary to ensure the desired comfort temperature.

Thermoregulation

Innovative hydraulic groups:

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