About Blacknoise
Blacknoise Deutschland GmbH, based in Hilden, is a specialized developer and supplier of axial, diagonal and radial fans as well as air-based cooling systems marketed under the NOISEBLOCKER® brand. As a full-service provider, the owner-managed company supports industrial customers along the entire process chain: from requirements analysis, CAD design and 3D visualization to rapid prototyping, standard-value and performance-curve measurements, and sound pressure determination with psychoacoustic analysis. In its own development laboratory with measuring and test rigs and a low-dB measurement chamber (conditioning down to zero dB), acoustic and fluid-mechanical analyses are carried out. High-quality plastics such as Makrolon® (polycarbonate), glass-fiber-reinforced plastics, PBT and ABS are used for rotors and components, some with patented Multiframe and bionics technology. Series production of small to medium volumes, including very small series, is handled by manufacturing partners in the Far East; customers come from, among others, the electrical, IT, datacenter, HVAC, medical and communications technology sectors.

Materials & Processes
Makrolon® (Polycarbonate)
High-toughness polycarbonate for rotors with high internal vibration damping, dimensional stability and durability in continuous operation.
Glass-fiber-reinforced plastics
Used for rotors and highly stressed fan components to ensure torsional stiffness and dimensional stability.
PBT (Polybutylene Terephthalate)
Standard injection-molding material for fan components with lower damping and stability requirements.
ABS
Standard plastic also used in injection molding for fan components.

Quality & Testing
Quality assurance is carried out in the company's own development laboratory in Hilden with measuring and test rigs for standard-value and performance-curve measurements as well as a low-dB measurement chamber with conditioning down to zero dB for sound pressure determination and psychoacoustic analyses (Sone according to Zwicker). Prototypes are tested in-house for all functions and characteristics before series release.
