InfiniSpring® Acoustic Direct Hanger and Low Height Acoustic Ceilings

InfiniSpring® is a thin spring and this offers possibilities for space savings in vibration and noise isolation applications. To minimize the space above the visible soundproofed ceiling we developed a new type of acoustic direct hanger solution, which enables extremely low height soundproofed suspended ceilings. In buildings lower space can minimize the building costs and lower height rooms can be equipped with soundproof suspended ceilings.

Concrete Inertia Base with Integrated Springs

By utilizing InfiniSpring® a concrete inertia base can be manufactured as a pure sheet metal component. The concrete inertia base reduces equipment vibration, decreases motions during start and shut-down, prevents movement between driving unit and non-driving unit and functions as a structure borne noise isolator. InfiniSpring® concrete inertia base is efficient and very straight forward way for installing mechanical equipment resiliently.
