Vibration Isolation and Seismic Control

Vibration Isolation and Seismic Control

Mechanical vibration and vibration-induced noise are common sources of occupant complaints in modern buildings. Vibration is caused by reciprocating motion from rotating components within mechanical equipment. All reciprocating, or rotating equipment should be isolated to reduce transmission of vibration into the structure. Senior Flexonics provides technical assistance in the selection and specification of tailor-made isolation systems and vibration isolation products that enable building owners to install complex heating, ventilation and air-conditioning systems without the worry of vibration problems.

Senior Flexonics vibration isolation products have been used to reduce the transmission of noise and vibration from mechanical equipment onto a building structure, support, isolate and suspend mechanical equipment, and to protect equipment from damage during seismic activity.

Products

Spring Vibration Isolators

Spring vibration isolators are used to reduce the transmission of noise, shock, and vibration produced by mechanical, industrial or process equipment into or within a building structure.

We offer Free Standing, Restrained and Housed Models depending on the application.

Typical Isolated Equipment includes:

  • Pumps
  • Fans
  • Cooling Towers
  • Rooftop Units
  • Chillers
  • Boilers
  • Compressors

Isolation Hangers

Vibration Isolation Hangers are the solution for noise and vibration reduction into a structure from piping, ductwork and suspended equipment.

Ranging from light duty to heavy duty applications, many different models are available using combination of springs, neoprene or fiberglass.

Thrust Restraints

ASHRAE recommends that thrust restraints be used for all fan heads, suspended fans, and all base-mounted and suspended air-handling equipment operating at 2 inches or greater total static pressure (TSP).

Total fan thrust can be calculated using the following formula:

Flexible Connectors

Flexible Connectors prevent stresses due to expansion and contraction, isolate against the transfer of noise and vibration, and compensate for misalignment.

Pipe Riser Isolation

Riser supports, anchors, and guides isolate the pipe from the structure to minimize noise and vibration transmission, while also allowing the pipe to expand and contract with minimal change in the support forces. Senior Flexonics offers engineering services to assist in the design of your riser system.
