Henkel developed BERGQUIST® brand double width, double inlet (DWDI) blower technology to meet the cooling demands of higher thermal density electronic systems. As these applications become more power-intensive, axial fans are challenged, resulting in increased noise and reduced reliability. Henkel’s airflow technologies push the conventional boundaries of active air cooling and enable effective temperature control of higher power density products.

Cooling Strategy Changes as Power Density Increases

true

BERGQUIST airflow products are recommended for applications where acoustics are the primary consideration. The unique design and aerodynamic refinements allow Henkel blowers to produce significantly less noise as compared to conventional fans. Depending on the application design and space availability, maximum noise reduction strategies can be integrated using creative blower arrangements. Henkel application specialists work directly with customers to assess specific requirements and deliver a solution with the lowest possible noise and best thermal performance.
