From small pumps and generators to entire buildings; VISOTECH can treat all vibration issues. Backed by GERB, the German experts in this field, VISOTECH now makes these latest technology high quality systems available to our Australian and New Zealand customers.
The advantages offered by GERB systems are highly sought after by mechanical contractors and acoustic specialists. In situations where up to 99% vibration isolation is required, such as hospitals or office complexes, springs are extremely capable solutions. This is why Visotech Australia supplies GERB spring isolation systems to some of Australia and New Zealand's most sensitive and high profile projects.
Visotech Australia, backed by the expertise and 100+ year experience of GERB engineers, can design and supply the most sophisticated custom solutions to address excessive vibrations.
This is why Visotech Australia supplies GERB spring isolation systems to some of Australia and New Zealand's most sensitive and high profile projects.
Visotech Australia vibration isolation systems range in size. The smallest spring systems are used for small plant and equipment such as pumps and generators. The largest spring systems are used to support entire buildings or power stations. No application is too large for GERB technology.
Visotech also designs and supplies high-tech visco damper systems. These are used in pipe systems and any application where damping rather than isolation is the main concern.
Another specialised application where Visotech/GERB can assist is with the design and supply of tuned-mass dampers. These are used to conteract sway induced by wind or humans in structures such as pedestrian bridges or tall buildings. This complex area of engineering is one of GERB's great stength. This is recognised by the fact that GERB tuned mass dampers have already been used extensively on some of Australia's most iconic recent projects.
Rail isolation is also a major field of activity for Visotech/GERB. The floating slab track systems are particularly interesting solutions for highly populated areas. Of course, solutions to isolate buildings from the vibrations generated by rail in close proximity are also very common. GERB has extensive experience and project references for such projects.
A recent addition to the GERB range of specialised solutions is a spring damper combo custom designed for the vibration and acoustic isolation of swimming pools. The design of concrete swimming pools in multi-residential high-rise complexes is becoming the norm. But when these pools are above inhabitable space, the noise and vibration at pool level needs to be eliminated. GERB has developped a solution that gives 98% isolation, but also limits the height required under the pool shell to only 150 mm ! The springs are delivered pre-compressed, allowing for minimal deflections under emptying and filling cycles required for the maintenance of the swimming pool.
A new product also developped by GERB for the Australian and New Zealand markets is a range of seismic spring mounts with internal restraints. Designed to meet the requirements of AS1170.4, these mounts can also include internal damping in the form of Sordino wrap or separate fluid dampers. This range is perfectly suited to gensets in hospitals and any other disaster recovery infrastructure.
Elastic Support of Printing Presses
Owing to their high-speed rolls, rotary printing presses cause vibrations In the machine itself as well as in its foundation. Therefore, in many cases right up to the present a large concrete foundation is foreseen which can be placed on piles should the subsoil be unsatisfactory.
Vibration Control of Piping Systems
Pipework dampers are frequently used for the protection of piping systems and other components in power plants and industrial facilities. GERB pipework dampers are highly effective viscoelastic elements, well proven in numerous installations. Already in 1951 Viscodampers® were patented for pipe applications.
Elastic Support of Machinery and Equipment
The most common use of Visotech GERB vibration isolation solutions in Australia and New Zealand is with plant and equipment. Eliminating these vibrations is important both for the health and safety of workers near these machines, but also for the machines themselves.
Tuned Mass Dampers for Bridges, Buildings and other Tall Structures
Wide span structures such as bridges, stairs, and roofs, as well as tall, narrow structures such as chimneys, antennas, masts and buildings, can be easily excited to high vibration amplitudes in their first or higher eigenforms. Excitations can be caused by wind forces, pedestrian traffic, machinery or earthquakes. Natural frequencies and damping are typically low for these structures. With GERB tuned mass dampers (TMD), these vibrations can be easily reduced.
Earthquake Protection for Machinery, Buildings and Equipment
With the Newcastle earthquake and the more recent Christchurch event in mind, Australian and New Zealand architects and engineers are taking earthquake protection of infrastructure and buildings very seriously. Visotech can help with very the design and supply of specific and customised earthquake protection systems.
Vibration Isolation of Buildings
The isolation of entire buildings from outside vibrations is a very specialised field of expertise. Visotech Australia/GERB have been working on such projects for many years now, all over the world. We can work with architects and engineers to design and supply vibration isolation systems customised to each project's exact requirements.
Elastic Support of Gas and Diesel Generators
Large gas and diesel engines are used for many purposes, i.e. trains, ships and for local power generation. In all cases, foundations for these engines must be both economical and effective. Elastic support of this equipment meets these requirements.
