The ACTA range includes open chamber boilers with powers of 24 kW and 28 kW. The ACTA series is suitable for heating and domestic hot water production. ACTA NEW 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 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 is a high efficiency boiler: the most compact exchanger, with reduced fin pitch to increase their number and ensure maximum efficiency. The large heat exchange surface is guaranteed by the helical section of the passage pipes and by the lamellar structure. The high exchange efficiency is guaranteed by the double circulation in counter flow. 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 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 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. Reliability and security 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 Warranty The warranty on this item is 24 months from the date of purchase.
