For large process exhaust flows, Munters manufactures concentrator equipment with zeolite rotors arranged in parallel. Single concentrator boxes can be shipped to treat exhaust streams as large as 100,000 cfm (160,000 m3/hr).
The concentrated air from each rotor is combined into one stream and sent to a common oxidizer for VOC destruction. Additional concentrator boxes can be added as needed to treat even larger flow volumes.
For processes that produce variable exhaust flow rates, the system can be designed to allow for extreme flexibility in operation by isolating certain rotors depending on the exhaust sent to the system. This feature will offer even greater operating cost savings.
