Kinetics model cib-h inertia base frames are specifically designed and engineered to receive poured concrete, and support mechanical equipment requiring a reinforced concrete inertia base. Inertia bases are used to support mechanical equipment, reduce vibration amplitude, provide for attachment of vibration isolators, prevent differential movement between driving and driven members, reduce rocking by lowering equipment center of gravity, reduce motion of equipment during start-up and shut-down, act to reduce reaction movement due to operating loads on equipment, and act as a partial noise barrier. Typically, kinetics model cib-h inertia base frames are used with poured concrete, and supported by kinetics noise and vibration isolators for reciprocating air and refrigeration compressors, chillers, heat pumps, close-coupled pumps, base-mounted pumps, centrifugal fans, internal combustion engines and similar types of equipment. Cib-h inertia base frames are specified for projects requiring base sizes not covered by cib-l inertia base frames.
