Application field: Average/small air flow, average/high concentration.
The unit is essentially made of a centrifugal fan and a sole apparatus containing the combustion chamber, a heat exchanger and a burner.
The case is externally covered with an insulating material with a thickness suitable for:
o limiting the heat dissipation towards the environment,
o minimizing the consumption of auxiliary fuel,
o keeping the surface temperature of the external sides at a value lower than 60°C.
The size of the combustion chamber, made of materials supporting high temperatures, guarantees a minimum gas permanence time of 0.6 s at the minimum combustion temperature of
The combustion temperature is maintained by means of a modulating air-vein burner, complete with a fuel feeding ramp compliant with the EN 746-2 regulation. This type of burner uses the process air as comburent air.
The combustion chamber is contained into a second chamber with a higher diameter which constitutes the external unit body.
The concentric ranks of the pipes constituting the highly efficient heat exchanger are installed in the space between the two chambers.
It is possible to further recover the heat going out of the system
