1、 Working principle
Air duct humidifier, also known as air duct wet film humidifier, is named after the installation of a wet film humidifier inside a specially designed section of air duct. It fully utilizes the humidification principle of the wet film humidifier and organically combines it with the air duct to achieve the purpose of humidifying a certain space.
2、 Actual characteristics
1. Good sealing and high strength.
2. Isothermal humidification with high humidification efficiency.
3. Flexible and easy installation, saving space.
4. The local humidification effect is significant.
5. Not only does it have the advantages of a wet film humidifier, but it also effectively overcomes the problem of high air duct speed.
3、 Usage conditions
1. Water quality: ordinary tap water or equivalent water quality
2. Water supply pressure: 0.05-0.7Mpa
3. Inlet air temperature: 6-60 ℃
4. Water supply temperature: 4-30 ℃
5. Wind speed of duct section: 0.5-2.8m/s
