VIBRO BASE INERTIA VRCB

The Model VRIB VIBRO BASE Inertia VRCB transforms mechanical equipment foundations through innovative engineering. When filled with concrete, this precision fabricated frame creates a reinforced inertia base that delivers exceptional vibration control, structural stability, and equipment support.

The system features an integrated design combining perimeter steel channels, isolator mounting brackets, reinforcing steel rods at 203 mm intervals, and pre positioned anchor bolts. This unified structure strategically uses steel under tension and concrete under compression, achieving superior strength and rigidity while minimizing material usage. The result is an inertia base that outperforms conventional heavy steel designs in both stiffness and long term durability.

VIBRO BASE frames arrive fully welded and installation ready, drastically reducing on site labor and project timelines. Available in thicknesses from 150 mm to 350 mm, these frames accommodate diverse mechanical equipment including centrifugal chillers, reciprocating compressors, pumps, fans, and engines. When paired with appropriate VIBRO ISOLATORS, the system provides superior equipment isolation, vibration amplitude control, and secure anchorage while lowering equipment center of gravity and blocking airborne noise transmission effectively.

Description

frames are offered in thicknesses ranging from 150 mm (6″) to 350 mm (14″). Each unit includes integrated isolator brackets, a steel channel perimeter for concrete pouring, 13 mm (½”) reinforcing rods spaced at 203 mm (8″) intervals in both directions, and pre-positioned steel anchor bolts. Frames are delivered to site fully welded and ready for concrete filling, significantly reducing on-site labor and installation time ensuring optimal cost-efficiency.

VIBRO BASE inertia base frames are purpose-engineered to accept poured concrete, forming a reinforced foundation for mechanical equipment that demands a concrete-filled inertia base. These bases serve a wide range of functions: they support mechanical systems, minimize vibration transmission, provide secure mounting for vibration isolators, and prevent misalignment between connected components. Additionally, they help stabilize equipment by lowering its center of gravity, reduce movement during start-up and shut-down cycles, absorb reaction forces from operational loads, and act as an effective barrier to airborne noise.

Typical applications for VIBRO BASE inertia base frames—when filled with concrete and supported by VIBRO ISOLATORS—include open-type centrifugal chillers, reciprocating air and refrigeration compressors, chillers and heat pumps, close-coupled and base-mounted pumps, centrifugal fans, internal combustion engines, and other vibration-sensitive equipment.

Isolation bases shall consist of concrete cast into precision-fabricated inertia base frames, with steel components designed and provided by the isolator manufacturer. The concrete is to be poured into a fully welded steel frame that includes pre-positioned anchor bolts for equipment mounting, 13 mm (½”) diameter reinforcing bars spaced at nominal 203 mm (8″) intervals in both directions, and recessed isolator brackets to minimize equipment mounting height and reduce the overall footprint of the base.

The base thickness shall be no less than 8% of the longest span between isolators, with a minimum of 152 mm (6″), or as otherwise specified in the project drawings. For pump installations, inertia bases must be dimensioned to accommodate piping elbows, or supplemented with additional support using VIBRO ISOLATORS where required.
