NHEXT®

commercial stainless steel heat exchanger - burner door - efficiency
NHEXT®

The leading technology of water tube commercial stainless steel heat exchanger

Nhext® (New Heat EXchanger Technology) is a commercial stainless steel heat exchanger offering huge performance at output up to 2000 kW.

The new patented multichannel manifold technology combined with increased tube diameters facilitates water flow circulation and reduces water pressure losses.

Nhext® water tube commercial stainless steel heat exchanger technology enables ultra low fume pressure losses.

Nhext® is equipped with the Bluejet® burner that helps to reduce NOx and CO emissions.

Product benefits +
High Performance
The NHEXT ® technology allows a very high efficiency across the whole operating range. It can reach over 109% energy efficiency.
Low water pressure losses
The new multi-channel manifold technology combined with increased tube diameters allows a reduction in water pressure losses, thanks to a facilitated circulation of water.
Compact & lightweight
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.
Huge turn-down ratio
The Bluejet® premix burner allows a considerable reduction of NOx thanks to its unequalled turn down ratio, from 1 to 30. This exceptional ratio allows gas consumption to be optimized. This also authorizes a great reduction numbers of ignition cycles.
Ease of maintenance
By removing only a few nuts, full access to the combustion chamber is easy at any time.
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
