Engineering support

A baghouse system audit determines your equipment’s requirements and limitations and facilitates the design of viable solutions to optimize operation and maximize capacity. FLSmidth AFT application engineers have valuable field experience in ventilation systems and can analyze your application in detail, regardless of the equipment style or manufacturer.

By analyzing the air pollution control system and physical installation, we can determine the changes necessary to solve performance problems. This might involve modifying an existing installation, a simple refurbish or upgrade, or a complete modernization of your equipment. We can also investigate how to optimize the rest of the system, including enclosures, hoods, ductwork, the fan and even the stack.
