Effectively decouple vibrations caused by compressors

Compressors are found as components in various systems such as heat pumps or HVAC devices. The vibrations to be decoupled are mainly caused by the compression process of the refrigerant. Thanks to the wide range of Isotop®, Sylomer® and Sylodyn® products, standard solutions can be selected for every requirement.

Advantages of elastic compressor bearings

Reduction of primary and secondary airborne noise (noise level)
Long service life – permanently elastic and therefore long-lasting effect
Very low natural frequencies possible (from 3Hz)
Weather and UV-resistant, highly effective even in cold temperatures

Multiple bearing concepts for compressors in heat pumps

As a general rule of thumb, the closer the elastic bearing is to the compressor, the more effective it is. With heat pumps, decoupling the internal compressor has a direct effect on the primary airborne noise. There are three options to choose from, which differ in terms of their performance.

Two-step decoupling

With two-step decoupling, the compressor itself is placed on an elastic bearing and then mounted on an intermediate plate. Further elastic elements are installed underneath the intermediate plate. This double isolation leads to a significant improvement in the low-frequency range and considerably reduces noise.

Bearing with intermediate plate

An additional intermediate plate offers the advantage that the optimal bearings can be selected. These bearings are closer to the maximum capacity and therefore have a lower natural frequency. This is particularly advantageous for lighter scroll compressors in heat pumps. If additional components are mounted on the intermediate plate, this also reduces the mechanical loads on the refrigerant supply lines.
