Industry solutions

VOCs source:gravure printing machine, compound machine, etc

Common components:ethyl acetate, propyl acetate, etc

Characteristics of waste gas:large air volume, medium and low concentration, less dust

Solution:all in one runner

*Flexible packaging industry order switching fast, concentration fluctuations, if the use of traditional RTO may cause excessive energy consumption

*Compared with RTO, the installed power of All in One rotor is greatly reduced, and no natural gas can be used for electric heating

Case 1:gravure printing machine and compound machine of a soft package printing enterprise in Zhejiang Province adopt All in One  Machine with ZCR

Molecular sieve rotor + thermal oxidation • Regenerative thermal oxidation RTO • Adsorption recovery
