Co-Ordinate Measuring Machine isolated using a reinforced concrete foundation block supported on

STUDFLEX Rubber Pads.

Quad Layer STUDFLEX Pads in

Natural Rubber providing:

• 14.4mm deflection on each Pad giving an

isolator Natural Frequency of 4.8 Hz.

• System capable of providing isolation of

vibration down to nearly 7Hz thus giving

maximum protection against disturbances

from the presses and other mechanical

plant which are in close proximity.

Industrial Isolation

Our wide range of anti-vibration mountings provide the right level of reduction that

is required so the forces produced by building and industrial equipment are

attenuated

We are involved in:

• Power Generation

• Air Handling Units

• Plantrooms

• Pipe work

• Cooling Towers

Studflex Pads / Springs Floor

• We protect the equipment and structure from vibration fatigue.

• We protect nearby premises from the vibrations & sound produced by Plant

Room equipment, Air Handling Units, Power Generators, etc.

• Our Key Advantage? Our in-house data processing capability enables us to evaluate the

most complex problems in 6 Degrees of Freedom using our proprietary CRMS software.

• CRMS output is balanced with real world experience in all

types of applications by highly trained Applications Engineers.

• We do this to ensure that there are no factors that would

affect performance that go unreported.

We analyse:

• Translational modes:

• Vertical

• Transverse

• Longitudinal

• Rotational modes:

• Yawing

• Pitching

• Rolling
