Baltimore Aircoil Company (BAC) seeks to identify materials and technologies that can deliver sound attenuation to their industrial heat rejection equipment. Primary focus is to attenuate/cancel noise from three main characteristics of this equipment: water movement (e.g. spraying, splashing…), air movement, and rotating mechanical components (e.g. fan, motor, belts, bearings…). These materials/technologies could greatly enhance the adoption of our products, especially in densely populated area where sound level restrictions hinder the deployment of BAC’s highly energy and water efficient heat rejection solutions.
Specifically, we are seeking technologies that can provide increased functionality in a few key areas:
1. Airflow performance
Existing sound attenuation usually increases measurably resistance to airflow of heat rejection equipment, as it typically obstructs the path of the air entering and/or exiting the equipment:
With increasing focus on fan and motor energy efficiency and power consumption requirements of industrial cooling equipment, BAC is interested in new materials and technology that enable similar or better sound attenuation than current technology, with significant reduction in airside pressure drop increase compared to existing sound attenuation technologies and products.
2. Weight/volume reduction
Existing sound attenuation options are voluminous and usually added the existing base products, leading to significant increase in overall weight and volume:
BAC is interested in new materials and technologies that enable similar or better sound attenuation than current technology, with significant reduction in weight and volume compared to existing sound attenuation.
Proposed materials/technologies could either be external add-ons to our equipment, similar to current sound attenuation products, or preferably be integrable to baseline product construction (e.g. coatings or alternative materials of constructions, louvers and/or fan guard replacement…). Additionally, both passive and active (i.e. powered) solutions will be considered.
Please note: all proposed technologies must have advanced beyond the conceptual stage.
Key Success Criteria
All proposed technologies will be evaluated on their potential to positively impact one or more of the following characteristics:
- Resistance to airflow
- Durability – Technologies should be able to performance reliably and long-term (20+years) in harsh outdoor environments heat rejection equipment operates in.
- Recyclability / Environmental Impact
- Ease of production
Please present information regarding how your proposed technology can meet one or more of the above criteria.
