Among all the harmful things that men have to bear with every day, the most annoying is noise, which is difficult to reduce and expensive to get rid of.
This is the reason why ELCO has developed quiet burners both by selecting sound absorbent materials, and by treating each noise sources internally. The main noise comes from the air intake and the air mixing in the fan wheel: all the ELCO burners are equipped with a sound trap on the air intake channel leading to the fan. This brings the acoustic level to a compatible value in respect of the environment.
