Shop / Isotop Vibration Dampers
Vibration dampers help machines and devices operate more quietly and efficiently. Without effective vibration dampers, vibrations will cause unpleasant noise disturbance and potential damage to the structure of the building. Vibration dampers absorb these vibrations and prevent them from being transferred to the building, extending the service life of the device and increasing comfort levels in living and working areas. High-quality vibration dampers combine low natural frequencies with excellent stability. In applications such as the internal decoupling of compressors in heat pumps, the pipework is protected, and any vibrations are decoupled.
Vibration dampers must be able to effectively isolate a broad range of frequencies. Having a low natural frequency is the best way to achieve this. Note that the ratio of excitation frequency to natural frequency should be greater than 1.41. Only then will both low and high frequencies, as well as every type of vibration, be minimised. In the case of a heat pump, for example, vibrations are perceived as airborne noise.
To ensure uninterrupted operation, the dampers must be durable and resistant to wear and environmental conditions. Of particular relevance here is the choice of material, which should be resistant to temperature fluctuations, moisture and chemical effects. This will ensure that the vibration dampers perform reliably well into the future.
The quick and easy installation of the dampers reduces overall costs and the amount of time spent on their installation and maintenance. These are important aspects for installers and maintenance engineers, since straightforward handling results in faster commissioning and shorter downtimes.
