Extraction system takes on hazardous propellants
Every hour, 40,000 m³ of air from an aerosol filling system passes through the fans installed by us at this silicone manufacturer. The air contains hazardous propellants that are transported to the thermal oxidizer.
Extraction systems on every roof of the 7 production facilities
During the filling of aerosol cans, small amounts of propellant are released. These gases are harmful to both people and the environment and must be captured and directed to an thermal oxidizer. Therefore, each filling room requires both machine and room extraction in compliance with the applicable ATEX standards. Each room has been equipped with 2 to 3 extraction fans that direct the air to a central duct.
In six of the seven rooms, propellant is filled into aerosol cans, while the seventh room houses the R&D department. The combined volume of hazardous gases in these rooms poses significant health risks. To address this, we designed a system for each room that extracts the gases close to their source and transports them to the thermal oxidizer.
This approach resulted in 2 to 3 fans per production unit, each equipped with 1 or 2 air filters. This powerful combination ensures the manufacturer meets stringent environmental regulations.
Piperack expansion
The comprehensive service Callens has provided here for the past five years is, once again, the cherry on top that completes the installation. We extended the existing piperack to transport the gases via an overpass to the RTO thermal oxidizer.
