The technology behind Multi-Wing’s rapid global growth
With nearly nine decades of aerodynamic expertise, Multi-Wing has evolved from a small Danish workshop into one of the world’s most specialized fan and airflow solution partners. What began with mechanical impellers for diesel engines has become a global technology platform enabling quieter, more energy-efficient cooling for industries as diverse as HVAC, data centers, agriculture, and construction.
The company’s heritage in modular impeller design remains central, but its mission now extends beyond airflow components to complete, optimized air-moving systems, integrating motors, electronics, and smart controls to improve performance and sustainability across applications.
COO Morten Knudsen explains how Multi-Wing’s aerodynamic expertise and global presence are helping industries meet new performance and efficiency challenges.
“We operate worldwide across North and South America, Europe, China, India, Southeast Asia, and Australia,” Morten begins. “Our core strength has long been in the off-highway market, covering engine cooling for construction and agricultural machinery. As this sector moves toward electrification, we’ve developed the DCmax™ series: aerodynamically optimized, energy-efficient electric axial fans. The series are perfect for cooling powertrains in electric and hybrid systems, but also brings notable efficiency gains for traditional diesel engines.”
To meet stricter performance and emissions standards, Multi-Wing has also introduced the PMAX impeller series, engineered to deliver higher pressure and improved efficiency across a wide range of off-highway cooling systems.
“We have a long development history with impellers; some of the designs we created in the 1960s and 1970s are still in production today,” Morten notes. “Our latest generation builds on that legacy with a complete portfolio from 30 centimeters to 2.5 meters in diameter, giving OEMs precise control over airflow and performance.”
Beyond off-highway equipment, Multi-Wing continues to innovate in HVAC/R applications, from industrial and commercial ventilation to refrigeration and heat exchange. Its C- and L-series axial fans are designed to meet stringent low-noise and high-efficiency requirements, helping customers achieve better energy performance and lower operating costs in modern building environments.
Together, these developments illustrate how Multi-Wing’s ongoing evolution – from component manufacturing to integrated airflow solutions – is enabling smarter, cleaner, and more flexible cooling across industries.
Few markets are growing as fast, or demanding as much innovation, as data centers. As global demand for cloud computing and AI infrastructure accelerates, operators are under intense pressure to expand capacity while improving cooling efficiency and reliability.
“Data centers are a huge growth opportunity for us, especially as players in this space are fighting for sufficient capacity and the requirement for cooling is in high demand,” Morten confirms. “We’re seeing significant investments in the data center industry in North America, and we’re starting to see them in Europe and the Asia-Pacific region. We believe data centers will drive much of the innovation and investment in the fan and cooling markets over the next five years.”
To meet this growing demand, Multi-Wing has developed axial fans designed specifically for high-performance thermal management, handling higher air temperatures and pressures while maintaining exceptional energy efficiency. These technologies are helping operators lower their Power Usage Effectiveness (PUE) and improve uptime as data density increases.
This segment has quickly become one of Multi-Wing’s fastest-growing markets, shaping new directions in both product development and system integration. The company’s investments in R&D and capacity, including new motor and drive capabilities, are positioning it as a key partner for the digital infrastructure industry’s next stage of growth.
To stay ahead in rapidly changing cooling markets, Multi-Wing combines organic growth with carefully chosen acquisitions that strengthen both its technological depth and regional reach.
In 2022, the company acquired Fabrika Special Motors in Denmark, a developer of advanced electric motors and drive electronics.
The following year, Multi-Wing took another strategic step by acquiring VIP Air Empowerment in Italy – a specialist in fan systems and integrated airflow solutions. With more than four decades of experience, VIP brought valuable know-how in complete system design and a 5,000 m² production and R&D site in Milan.
These acquisitions significantly boosted Multi-Wing’s in-house R&D in electronic drives and motor technologies – critical capabilities for developing next-generation, high-efficiency fan systems for HVAC, data center, and off-highway applications.
At the same time, the company is scaling its manufacturing footprint in Monterrey, Mexico – one of North America’s most dynamic industrial hubs for HVAC and data center equipment. The 10,000 m² facility, opened just a few years ago, is already undergoing expansion to meet rising demand. By mid-2026, it will serve as a high-volume production site for advanced axial fans across North America.
“Each of these investments has a clear purpose,” explains Morten. “By combining aerodynamic, electronic, and system-integration expertise across regions, we can deliver truly optimized airflow solutions, faster, smarter, and closer to where our customers operate.”
For Multi-Wing, innovation and sustainability go hand in hand. The company’s modular designs extend product life and reduce waste, while its fans are made from up to 92 percent recycled materials. Multi-Wing is aligned with the Science-Based Targets initiative (SBTi) and is progressing toward 100 percent renewable energy by 2030.
“Increasing fan diameter can deliver efficiency gains of up to 30 percent,” Morten explains. “That’s why we’re investing in larger, smarter designs that use less energy per cubic meter of air moved – a win for both customers and the planet.”
From speaking with Morten, it’s clear that Multi-Wing’s commitment to innovation and efficiency continues to drive every decision. As our conversation closes, he reflects on what lies ahead for the company.
“2026 will bring a steep growth curve as we bring our newly expanded facility in Monterrey up to full production capacity,” Morten says. “We remain focused on developing the next generation of products, and as demand for fan solutions continues to grow, we must ensure we have the capacity and flexibility to capitalize on that demand.”
He explains that this flexibility, both in products and supply chain, is a defining strength. “Customers can achieve their exact requirements by adjusting parameters on the impellers, such as pairing them with different components or changing blade angles,” he notes. “We’ve built this adaptability throughout our supply chain, and we’re investing further to manufacture key subcomponents in-house.”
That adaptability will be essential as global cooling needs become more complex. Multi-Wing’s combination of aerodynamic expertise, system integration, and sustainable design positions it well for the next wave of electrification and digital infrastructure.
Morten concludes: “Over the next five years, I see Multi-Wing doubling or even tripling in volume. That’s why it’s crucial to maintain our focus on enhancing production capacity, stabilizing our supply chain, and continuing to innovate sustainable products.”
