QUADRIFOGLIO B

STAINLESS STEEL CONDENSING GENERATOR

> STRENGTHS:

It reaches one of the highest seasonal space heating efficiencies in its category: η_s 94%

A+ SYSTEM: combined with the modulating remote control and the external probe (optional) it reaches the top efficiency class A+ (scale from G to A+++)

Steel generator with vertical configuration, low thermal load, large water content and passing flame

Stainless steel AISI 316 Ti exchanger consisting of a pipe bundle with patented helical configuration and designed to optimise heat exchange and flue gas condensation

Low NOx micro-flame premixed burner with front combustion. The extremely contained overall vertical dimension is such that the exchange of water/flue gases takes place over the entire extension of the exchanger. Quick opening system of the combustion chamber for inspection and maintenance

Control panel with parameter adjustment and setting, large interface screen and on-off switch

Pit for installing the safety valve as standard on the generator delivery circuit

Generator supplied by standard complete with temperature probes on the delivery and return and minimum water pressure switch

Flue gas exhaust on the right and left sides of the generator

Flue gas non-return system for cascade installations, set up by standard on each generator

Broad and complete availability of hydraulic, gas and flue gas accessories for cascade installations with banks of two or three generators

Technical Data

> ADVANTAGES OF QUADRIFOGLIO B:

Very high efficiency exceeding 109% in some working conditions

Range characterised by a wide range of available powers, from 70 kW up to 960 kW (bank of 3 x 320 kW modules)

The large volume of water of the generator allows the boiler to be connected to the system without the need for separating devices and allows for a very high design ∆t

Double return in boiler for the management of systems with circuits operating at different operating temperatures, thereby always guaranteeing the best stratification inside the boiler body

Minimum polluting emissions (class 6 according to EN 15502-1)

Electronic control of combustion with a microprocessor that modulates the single generator up to 20% of the maximum power

The generator electronics can manage installations in cascade, the production of domestic hot water with storage tank and system pump with sliding delivery temperature

Equipped with 0-10V input control signal to control the delivery temperature or the operating power for both single generator or equivalent generator bank
