We are seeking to identify technologies that can deliver improved energy efficiency and lower sound emissions to their industrial heat rejection equipment. The primary focus is to greatly exceed the minimum energy efficiency goals established by the second tier of the European Union’s Directive 327/2011 guideline

while providing industry-leading low sound performance, by ideally meeting or exceeding the 1.1.2020 efficiency levels listed in this working document:

For reference, the EU Directive 327/2011 guidelines establish minimum overall efficiency levels for the fan, electric motor, and driving arrangement assemblies. These technologies would support BAC’s mission of providing sustainable, high-efficiency cooling solutions while minimize the environmental impact of our highly energy and water efficient heat rejection solutions.
Specifically, we are seeking technologies that can provide increased performance in a few key areas:
1. Energy efficiency
Existing air movement technologies in BAC products are typically one of three types:
Axial fan (direct-drive or belt-driven):
Forward-curve centrifugal fan (belt-driven):
Backward-curve/radial unhoused centrifugal fan (direct-drive or belt-driven):
All with high-efficiency or premium efficiency motors.
With increasing focus on fan and electric motor energy efficiency and power consumption requirements of industrial cooling equipment, BAC is interested technology that enable industry-leading energy efficiency, with improved sound levels compared to existing technology.
2. Weight/volume/cost reduction
Existing fan and electric motor technologies, and more specifically high-efficiency, low sound options are heavier, more voluminous, and more expensive than the existing base products, leading to a significant increase in overall equipment weight, volume and cost:
BAC is interested in air movement technologies that enable better energy and sound performance than current technology, with a significant reduction in volume, weight, and cost.
Proposed technologies could be a fan and/or motor technologies, but we are also looking for alternatives to traditional means of moving air through heat rejection equipment, and priority will be given to innovative and highly differentiated proposals.
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 the following characteristics:
And one or more of these one or more of the following “optional” characteristics:
Please present information regarding how your proposed technology can meet one or more of the above criteria.
