3. The unit is equipped with functional sections such as a new return mixing section and a filtering section, a new return air mixing section, a primary efficiency filtering section, a secondary return air section, a surface cooling water section, a steam heating section, an electric heating section, a dry steam humidification section, a fan section, a medium efficiency filtering section, a flow equalization section, a noise reduction section, and a fan supply section, which can be flexibly selected and combined by design institutes and users.

4. The supporting fan of the unit adopts advanced KKF (or TDKF) type air conditioning dedicated double inlet centrifuge from home and abroad, which has the characteristics of high efficiency, low noise, and wide head range, and can meet the needs of low-pressure head cooling system, medium pressure head constant temperature system, and high-pressure head purification system.

5. The heat exchanger (surface cooler, heater) matched with the unit is made of copper tube with aluminum foil double flanged, mechanically expanded tube, with good rigidity, high heat exchange efficiency, low wind and water resistance, and can be used for both hot and cold purposes.

6. The unit adopts a polyester bag filter for filtration, which has the advantages of high filtration efficiency, low resistance, disassembly, easy cleaning, and replaceable filter material.

7. The heating section of the unit has two types: steam (or hot water) heating and electric heating, and the humidification section also has two types: dry steam and electric humidification. The design institute and users can choose according to their actual situation.

8. To meet the requirements of users for different occasions, purposes, and special performance, our company can design and manufacture according to non ruler specifications.
