The NHEXT® is the ultimate solution for commercial and industrial output: the new tube design combined with the central manifold optimizes water circulation, and the four fume passes ensure unparalleled efficiency.
Revolutionary in the field of combustion, the Bluejet® stands out as the reference burner on Sermeta heat exchangers thanks to its modulation capacity, flame retention and combustion quality.
This premix burner allows for the use of all gas types. It is also perfectly adapted for the use of auto-adaptive gas valves.
Full Heat Condens®
Based on Isothermic® technology, the Full Heat Condens® adds a Domestic Hot Water preheating function for combi boilers. Designed with additional hydroformed tubes, it recovers all energy from the combustion of gases. This innovation offers optimal performance and allows fumes evacuation at less than 20°C.
Cold Burner Door®
To reduce losses due to radiation from the heat exchanger and the temperature of the door surface, Sermeta created the Cold Burner Door. Installed exclusively on our heat exchangers, this innovation significantly improves their performance.
The cascade design of the TRIO, with its two combustion chambers, makes it possible to reach high levels of commercial and industrial outputs. It also offers a huge turn down ratio, reducing CO2 and NOx emissions and optimizing comfort level. It integrates a Flap® and a Stabilor® to optimize the air and gas mix.
The marriage of the composite and stainless steel at the heart of the boiler.
Its double casing stainless steel / composite ensures lightness and low radiation losses. Associated with the hydroformed coil, this concept enabled the development of condensing technology through a reliable, competitive and efficient innovation.
By superimposing the condensation and combustion chambers, the DUO offers outputs to meet the commercial market requirements. DUO benefits from maximum performance in minimal space.
Composed of hydroformed tubes, the “Classic” was the first Sermeta stainless steel heat exchanger. Its series production revolutionized condensation technology in the heating sector.
Sermeta invented the revolutionary concept of the hydroformed coils for heat exchangers. Exclusive technology, hydroforming is an industrial process which guarantees a uniform and constant space between the coils. This facilitates the fumes circulation and heat transmission as well as the natural cleaning process.
The stainless steel tubes of Sermeta heat exchangers are folded and then hydroformed, the space required is thus kept to a minimum.
