Vibration dampers

ChillPACs and HeatPACs are designed for either 4 or 6 vibration dampers. For installation on solid con-

crete floor, anti-vibration machine feet are sufficient. Such machine feet are designed for minimum 70%

vertical isolation (100% capacity).

For installation on decks, special dampers are often required. Please consult a vibration expert or a

Johnson Controls Denmark representative for further information.

To ensure optimum effect of each individual anti-vibration machine foot, the load on the feet must result

in roughly the same deflection of all machine feet, see Fig. 3. Deflection of a machine foot can be ad-

justed by increasing or reducing the load compared to the other supports by turning the adjusting rod.

Other damper types can be adjusted by using liner plates.
