Innovative solutions:
Vibration isolation for small and medium-sized plants and machinery
Appropriate vibration isolation and/or structure-borne noise damping in machinery, components, aggregates and buildings is becoming increasingly important to protect humans and material assets against vibrations. Spring elements and damped spring elements ensure that the vibration induced by the equipment - the source of the vibration - is not transmitted to the environment (isolation of source). Spring elements can also be used to isolate a vibratory system against vibrations induced
by the environment (isolation of recipient). We off er spring elements with or without integrated CRD type damping covering frequencies between 2.5 and 5Hz. All spring elements can be additionally equipped with viscoelastic dampers to adapt to increased damping requirements.

Design
Spring elements are designed as follows:
· same total height within a series
· large load range between 90 and 72,200N
· frequencies from 2.5Hz
· pressure- and form-locking height adjustment (also available in stainless steel) (optional)
· high-quality corrosion protection (CDP coated springs)
· CRD type damping using the same dimensions (optional)
· structure-borne noise damping (optional)
· lift-off device (optional)
Spring elements are suitable for use in a variety of applications. They provide the best solution for vibration and structure-borne noise isolation, for example in:
· fans or ventilation systems
· air-conditioning systems
· pumps or pumping systems
· electronic equipment
· measuring devices
· small and medium-sized power presses
