ACTA

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

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

Characteristics:

• High yields
• Primary copper exchanger, lamellar with high circulation
• Stainless steel plate sanitary exchanger
• High efficiency pump with low energy consumption
• Integration with SAVIO solar systems via 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
• Disposal of primary circuit thermal inertia.

Primary exchanger

ACTA is a high efficiency boiler: the most compact exchanger, with reduced fin pitch to increase the number and guarantee maximum efficiency.
The high exchange surface is guaranteed by the helical section of the passage tubes and the lamellar structure. The high exchange efficiency is guaranteed by the double counter-flow circulation. The exchanger is made of copper with a protective coating resistant to high temperatures.

Secondary exchanger

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

Control panel

• Summer/winter/off selector
• Heating temperature regulator
• Domestic hot water temperature regulator
• Digital and analogue pressure reading
• DHW temperature and heating displayed
• Display of fault diagnostics, lockout status and fault history
• Recommended filling display
• Display of annual periodic maintenance deadline
• Thermohydrometer for reading the water pressure on the primary side.

Integration with solar

ACTA 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 you to optimize the integration of the solar system with the boiler which intervenes only when necessary to guarantee the required comfort temperature.

Reliability and safety

Innovative hydraulic groups:

• 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 flow meter
• Easily accessible filling tap
• Drain cock
