High-pressure humidification by a low-energy pump, providing one or more humidification units with a built-in ventilator. Humidifying is obtained by atomising water under high-pressure to microscopic particles by means of a high-pressure pump. The ventilator distributes the particles to obtain uniform air humidity in the entire room. The high-pressure system is constructed as a low-noise, drip-free system. This means that the damping unit without problems can be placed in all production rooms - even if the floor-to-ceiling height is low.  The closed design minimises the formation of bacteria and the general cleaning needs.

Steam dampers will most often consist of a steam cylinder in which water is heated to a temperature of 100 º C and further until steam is formed. The steam is led directly into the room or through the channel system of the existing ventilation plant. When the water is boiled, minerals are deposited which will regularly be washed into the drain.

Humidification is effected through open vessels by means of small electrical units which oscillate releasing cold steam. The water level must be adjusted very carefully to the damping unit.
The damper is integrated in the channel system or with its own ventilator. The water in the level vessel must be led to the drain regularly.

Spraying is effected by leading compressed air through a nozzle where vacuum is formed. 
The vacuum leads water into the air and it is mixed with compressed air as a cold-water cloud. The capacity/spraying effect of the nozzles depends on the vacuum obtained. If this vacuum is changed for some reason, it will have an adverse effect on the capacity of the nozzle and consequently also on the operation factor.

Humidification occurs by water running down lamellas in the nozzle reservoir of a water wall.  After that, air passes through the reservoir and is in this way humidified. Most of the water falls down to the bottom of the reservoir - the so-called sump - from where it is pumped back and reused for humidification. A water wall is typically built into the existing ventilation system.
