KALDAIA 32/35 MTN
CONDENSING
Wall-mounted boilers:
Thirty years of experience in the design and creation of solutions for heating premises and domestic hot water have allowed us to create two ranges of high-quality boilers: condensing, both indoor and outdoor, and open-chamber with low NOx emissions. INNOVITA products are designed, tested, and manufactured entirely in our laboratories in Bosisio Parini (LC), thus guaranteeing a high level and quality of Made in Italy.
Features:
• Kaldaia is designed, tested and entirely produced in our Bosisio Parini plant, thus guaranteeing a high level and quality of Made in Italy
• The primary exchanger is made with a single stainless steel coil with a large internal section to ensure high efficiency and reduced pressure drops, furthermore the structure of the coil guarantees easy maintenance and reduced impurity deposits
• The high-efficiency, low-consumption class A circulator guarantees significant electricity savings
• The active combustion control system regulates the gas flow rate to maintain the air/gas ratio constant, thus obtaining reduced gas consumption and continuous control of polluting emissions
• Very silent
• Modulation up to 1:9
• Kaldaia is equipped with high-performance components
• The layout of Kaldaia allows quick disassembly of the main components
• Kaldaia is perfect for replacements and offers high performance on new and old generation systems
• Facilitated gas transformation: no mechanical operation on the product is necessary.
User interface:
Equipped with an easy-to-use digital display, Kaldaia is easily manageable by the user in a clear and intuitive way. The presence of function-specific keys allows the domestic hot water system and heating system temperatures to be adjusted and the operation of the appliance to be monitored.
