Where It Works

Using advanced aerodynamic design principles and computer simulation software developed by the National Renewable Energy Laboratory, SecondWind has developed a suite of products optimizing the recovery and conversion of high flow exhaust air into usable electricity. Our products are design-engineered, scalable, and our composite manufacturing allows our products to withstand the harshest environmental conditions.


SecondWind is works in partnership with the University of Washington’s school of Mechanical Engineering Wind Energy research department. Using their experience with expertise and access to today’s cutting edge design tools, we have designed a suite of products optimized for our applications.

Manufacturing Process

Architecting a manufacturing process with the use of 3D modeling, composite compression molding, and singular packaging affords fewer component parts, less factory floor time, quicker shipment to the customer, and will help enable a speedy install.

SecondWind works with a variety of vendors to fabricate individual component and completes final assembly at our factory in Redmond, WA.

Laboratory Testing

Design-tested and enhanced through rigorous Wind Tunnel analysis and modeling techniques, the results (with regard to computational fluid dynamics, aspect ratios, drag co-efficient, and angle), confirm and validate real world commercial use allowing SecondWind to produce a superior product, in a shorter timeframe, and at less cost than our competitors.

All laboratory testing was completed on the campus of the University of Washington, in the Kirsten Wind Tunnel.

Demonstration Installation

Rigorous market tests, including prolonged exposure to varying temperatures and environments in a variety of commercial exhaust system scenarios, have proven the strength and durability of the composite blades and energy-saving air foil design.

“With growing energy demands and increasing costs, SecondWind is uniquely positioned to aid building owners in reducing their HVAC electricity loads.”
