What is vibration isolation?
Vibration isolation products allow building owners to install complex heating, ventilation, and air-conditioning systems without the worry of noise and vibration problems.
The specialists at Hahn Mason partner with Kinetics Noise Control to provide:
- Technical assistance in selecting a tailor-made isolation system.
- Vibration isolation products to meet the required specifications of the project.
What are the benefits of vibration isolation?
Vibration isolation products are used to:
- Reduce the transmission of noise and vibration from mechanical equipment onto a building structure
- Support, isolate, and suspend mechanical equipment
- Protect equipment from damage during seismic activity
Design Questions to Consider
The following are examples of questions to keep in mind when considering vibration isolation or seismic and wind restraint for your next project:
- Is there equipment mounted on the roof that will require certified wind restraint?
- Does the mechanical equipment require Vibration isolation?
- Does any of the pipe or ductwork require isolation?
- Are there any delegated design elements Kinetics can offer custom engineering solutions for? (pipe stress analysis, Riser designs, etc.)
All piping systems have mechanical vibration generated by the equipment and flow induced vibration and noise. The vibration and noise are transmitted by the pipe and ductwork. The piping and ductwork systems must be flexible enough to reduce vibration transmission along the connected piping and permit equipment movement while maintaining isolation.
Pipe hangers and supports are necessary to prevent vibration and noise transmission from the piping system to the building structure.
Other types of Isolation and Vibration
Neoprene/Fiberglass Isolation Mounts
Neoprene and Fiberglass Isolation Mounts and pads are used to reduce the transmission of noise, shock, and vibration produced by mechanical, industrial or process equipment into or within a building structure.
Roof Curbs with springs and isolators
Roof curb isolation systems are designed for curb-supported rooftop equipment. Isolation curbs incorporate the roof curb and rooftop rail into the design. Roof curb isolation systems are designed with springs that have static deflections to meet the design criteria.
Inertia base frames and structural steel bases
Inertia base frames and structural steel bases are designed and engineered for use in supporting mechanical equipment. Typically used with vibration isolators for support and isolation of: chillers, pumps, compressors, centrifugal fans, air handling units, condensers, and cooling towers.
Flexible piping connectors
Flexible connectors prevent stresses due to expansion and contraction, isolate against the transfer of noise and vibration, and compensate for misalignment.
Seismic V-loops and U-Loops solve the problems of pipe motion caused by thermal pipe growth and the movements associated with seismic activity. Benefits of the seismic V-loops include limited amount of space required for installation and the ability to hold in heat compared to traditional large pipe loops. Another benefit is V-Loops do not introduce thrust loads on the piping systems whereas metal bellows and rubber expansion joints impose significant anchor loads due to the effects of static pressure thrust.
Construction of both V- and U-loops is unique in the fact that it creates a flexible product that does not expand when pressurized. They can be designed in nested configurations with relatively tight centering. Standard installation is in horizontal pipe runs with the V-loop elbow pointing straight down. The use of an eyelet can be used for installations outside of the standard installation. Construction of the V- and U-Loop can be manufactured with a variety of end fitting and also copper or stainless steel braided material.
Thrust Restraints are used to counteract the discharge force created by fans during operation. HSR Thrust Restraints are used in pairs and best utilized when located on the centerline of the discharge outlet of the fan, bridging the flexible duct connector.
