Evaporative type humidifiers VFB Type

[Single operation/floor type, room direct humidifier]
This type is suitable for rooms with high sensible heat load, such as data center.

In rooms with high sensible heat load, such as in communication rooms, computer rooms, electronic device plants, it is possible to use the generated heat to vaporize water, thus reducing the air-cooling load and saving energy.
Two models (4kg/h and 8kg/h), which have relatively high humidification capacity as a single operation Evaporative type, are available. This system provides natural and stable humidification according to the air conditions in the room, independent from the system and operation mode of the A/C unit.
