QUADRISTAR B

Flue gas circuit made completely from AISI 316 TI stainless steel. Heat exchanger made from a patented helical shaped tube bundle, designed to optimise heat exchange and condensation of flue gas.

Premix burner with diffusion grill and metal mesh for microflame combustion. Burner with front combustion featuring compact vertical dimensions to allow water-flue gas heat exchange along the entire length of the heat exchanger. Quick opening system in the combustion chamber (right or left) for inspection and maintenance.

Boiler control electronics able to manage cascade systems with master-slave logic, domestic hot water production with storage cylinder and heating system pump with outlet temperature compensation

Flue gas outlet from the right and left sides of the hot water generator.

Equipped as standard with anti return valve which prevents flue gas from returning through the boiler.

Very high efficiency up to 109,6% in certain operating conditions.

The large volume of water in the hot water generator means the boiler can be connected to the system without needing low-loss headers and can operate with a maximum temperature difference of 50°C between system flow and return.

Double return to the boiler (low and medium temperature) so as to correctly manage two systems at different operating temperatures and guarantee maximum stratification inside the boiler body and maximum unit thermal efficiency.

The microflame burner ensures combustion with very low polluting emissions. QUADRISTAR is certified class 5 for NOx emissions.

Microprocessor electronic control of combustion that allows modulation of hot water generator operation down to 20% of maximum output

ACCESSORIES AVAILABLE ON REQUEST

Motor-driven on-off valve For cascade systems of two or more hot water generators. Used to stop water circulating in the system when the hot water generator stops on reaching the set point. Diameters DN 50 and DN 65.

Condensate neutraliser Neutralisation system essential to bring the pH of the condensate to a value above 7, allowing it to be drained with household water, as required by legislation in force.

Outside probe. For the flow temperature compensation function, to be connected to the control unit.

FZ4 expansion module. To implement system electronic management functions.

Hydraulic and gas accessories. Full range of hydraulic and gas supply accessories for cascade connection of all 16 certified combinations.

Accessories flues. Full range of kits in the PPs for flues outlet directly into the atmosphere or into the cascade flue gas collector.

RANGE RATED

QUADRISTAR B is a “RANGE RATED” boiler in accordance with the requirements defined by standard EN 483.

In fact, heating capacity can be adapted based on system requirements, making the heating system as efficient as possible and guaranteeing the maximum performance declared by the manufacturer.
