DUO

commercial boiler - heat exchanger - compact shape
DUO

Maximum efficiency, compactness, power

DUO is a heat exchanger for commercial boilers. The hydroformed coils allow obtaining a minimal bulk. This product has made it possible to develop ranges of boilers occupying less space in boiler rooms, while maintaining maximum thermal comfort.

Suitable for commercial boilers, DUO is a heat exchanger in which the condensing chamber and the combustion chamber are superimposed, allowing it to achieve high output in minimal footprint

Product benefits +
Ease of maintenance
By removing only a few nuts, full access to the combustion chamber is easy at any time.
Compactness
The stainless steel tubes of the Sermeta heat exchangers are folded and then hydroformed, the units are therefore very compact.
    The compactness and lightness of our product range contribute to the development of boilers that occupy less space in boiler rooms.
Lightweight
The use of stainless steel offers unparalleled lightness to our products, allowing the commercial and industrial boilers development those are light and easy to install.
The Sermeta Signature
Reliability
To ensure an unrivalled reliability, we develop our products and their manufacturing processes in parallel.
    Our expertise allows us to internally develop automated, productive and innovative production lines. The automation ensures a consistent quality.
Longevity
Hydroforming is a proprietary industrial process that ensures a uniform and consistent gap between the stainless steel tubes. This facilitates the fumes circulation and heat transmission as well as natural cleaning process.
    Stainless steel is a material perfectly adapted to the condensation conditions. It offers many qualities:
  • Reliability
  • Robustness
  • Resistance to thermal shocks
  • Low thermal inertia
  • Long life
  • Low sensitivity to the pH of water
Ecology
Sermeta heat exchangers and their burners reduce CO2 emission by -25%. CO2 and NOx emissions from our heat exchangers are below regulatory requirements.
    Thanks to our 23 million heat exchangers on the market, the release of 21 million tons of CO2 is avoided every year, thus protecting our environment.
Quality
The quality is at the core of our manufacturing processes: 100% of our products are tested on the production line, that is 2 million of heat exchangers each year.
    Our 23 million heat exchangers worldwide in use demonstrate our products reliability and the customer service quality that we offer to our clients.
