Metso high humidity hoods

Metso closed hood is much more than an enclosure over the dryer section. It combines systems for ventilation, runnability and heat recovery, thus providing excellent tools for controlling drying performance and maintaining energy efficiency.

Metso has two hoods for different purposes. OptiHood for high speed large paper machines and ValHood for narrow and middle sized paper machines. Both have durable high humidity non-condensating construction.
