The vibration absorbers are designed for installation on commercial refrigerating systems and on civil and industrial air conditioning plants. The function of this item is to avoid the transmission of compressor's vibrations to the refrigerating system pipes, reducing the risk of damage and the noise level. The vibration absorbers can also compensate small thermal expansion of the piping.

INSTALLATION

1.) A vibration absorbers can be installed both on suction and discharge lines of a refrigerating system, as close as possible to the compressor. The vibration absorbers are not designed to compensate possible piping misalignment. Vibration absorbers should be installed perpendicularly to the direction of vibrations. When vibrations exist on two planes, two vibrations absorbers should be used, as shown on the fig.. For the maximum absorption of vibrations, the refrigerant line should be anchored at the end of the vibration absorber, as shown on the fig.

2.) Vibration absorbers can be installed vertically too, because they are designed to avoid the retention of condensing water in the wavy zone near to the connections. So there are no problems to install them with temperatures lower then 0°C.

3.) Vibration absorbers are not designed to absorb axial or torsion stress. Care should be taken to allow sufficient space for the vibration to avoid static compression or tension, after brazing on place.

4.) High speed of the refrigerant fluid can produce vibration and noise phenomena. In this case it’s advisable to install a larger size of Vibration Absorber.

5.) The connection of the vibration absorbers to the piping is normally performed by a brazing process. The specific design and construction of vibration absorbers allows welding without particular protections to prevent overheating.

WARNING!

Ensure a gap corresponding to the 2% of the total length of the vibration absorber device to compensate for possible thermal expansion.
