Exhaust Air Booster • DEC.EAB™

Exhaust Air Booster
DEC.EAB™

Traditional approaches to conveying Solvent-Laden Air (SLA) often involve a central fan at the Volatile Organic Compound (VOC) abatement system (e.g. DEC.SRU™ • solvent recovery, XTO™ • thermal oxidizers, etc.) pulling air through the entire ducting network. While effective for machines in close proximity, this can lead to several issues for distant equipment, primarily insufficient suction and imbalanced airflow across the system. This article introduces the DEC.EAB™ • Exhaust Air Booster, a groundbreaking solution designed to overcome these challenges, ensuring efficient and balanced SLA conveyance, particularly for machines located far from the abatement system. Interfaced with the DEC.ISC™ • Integrated Suction Control module, the DEC.EAB™ system offers precise and localized suction management, revolutionizing VOC abatement efficiency.

DEC.EAB™ • the solution for optimal SLA conveyance

In a conventional setup, a centralized powerful fan system at the VOC abatement system is responsible for generating the negative pressure required to draw Solvent-Laden Air (SLA) from all connected machines. For equipment situated close to the abatement system, this approach is generally effective. However, as the distance between the machine and the central fan increases, several problems arise:

Insufficient Suction for Distant Machines: the pressure drop across long ducting networks can significantly reduce the effective suction at the exhaust points of distant machines. This can compromise the capture efficiency of solvent vapors, leading to potential emissions and health hazards;

Over-Suction and Turbulence for Nearby Machines: to compensate for the pressure drop to distant machines, the central fan might need to operate at a higher capacity, resulting in excessive suction and potentially creating turbulence at the exhaust points of machines located closer to the abatement system. This turbulence can negatively impact machine operation, product quality, and even lead to premature wear of components;

Imbalanced Airflow: the differential pressure across the network can lead to an uneven distribution of airflow, with machines closer to the fan experiencing higher flow rates than necessary, while distant machines receive inadequate flow. This inefficiency can lead to increased energy consumption and suboptimal VOC abatement;

Ducting Network Stress: operating the entire ducting network at a very low pressure to guarantee sufficient suction for distant points can put undue stress on the ducting system, potentially leading to leaks or structural issues over time.

DEC.EAB™ is a dedicated, localized Solvent-Laden Air (SLA) booster designed to address the inherent limitations of centralized suction systems. Installed in the ducting network of a far-away machine, the EAB™ unit effectively conveys exhaust air to the VOC abatement system without requiring the entire ducting network to operate at a low pressure.

DEC.EAB™ • key benefits

Guaranteed Suction for Distant Machines: by providing localized boosting, the DEC.EAB™ ensures that even machines located at significant distances from the VOC abatement system receive the necessary suction to effectively capture solvent vapors, compensating for the pressure drops of the SLA ducting;

Avoidance of Turbulence for Nearby Machines: With the DEC.EAB™ handling the specific needs of distant machines, the central fan at the VOC abatement system can operate at a more optimized pressure, preventing over-suction and detrimental turbulence at the exhaust points of machines situated closer to the abatement system;

Reduced stress on ducting network: the DEC.EAB™ mitigates the need to heavily depressurize the entire ducting network, thereby reducing stress and potential wear on the system components;

Enhanced VOC capture efficiency: By ensuring consistent and adequate suction across all exhaust points, the DEC.EAB™ contributes directly to a higher overall VOC capture efficiency, improving compliance and environmental performance.
