RESTRAINED SPRING ISOLATORS FREE

Isolators shall consist of large diameter, laterally stable, steel springs assembled into welded steel housing assemblies designed to limit movement of the supported equipment in all directions. Vibration isolators shall be seismically rated, restrained spring isolators for equipment which is subject to load variations and large external forces. Operating static deflections are available to 2' (50mm) to and maintain a high degree of noise and vibration isolation. Model EFRSI Isolators are typically used to reduce the transmission of noise and vibration into supporting structure form equipment carrying a large fluid load that may be drained, such as boilers and chillers, and cooling towers which also require hold-down for seismic and wind loads. where motion due to wind loads must be minimized.Įasyflex Model EFRSI Seismic Control Restrained Spring Isolators are recommended as a noise and vibration isolator for mechanical equipment located near critically quiet areas when the equipment to be isolated has significant changes of weight during maintenance operations and for equipment subjected to seismic events, external forces, or high wind loads.

Easyflex Model EFRSI Spring Isolators are recommended for the isolation of vibration produced by equipment carrying a large fluid load which may be drained, such as boilers and chillers, and specially for the isolation fo cooling towers, air-cooled condensers, etc. Custom isolators with higher deflection and greater load capabilities are also available. EFRSI isolators are available with deflections upto 2' (50 mm) and with load capacities to 5,000 kg. To assure stability, the springs have a lateral spring stiffness than 1.2 times the rated vertical stiffness and are designed to provide a minimum of 50% overload capacity. Holes are provided in all isolators for bolting to the structure and to the supported equipment. Spring elements are complete with internal noise isolation pads and have an adjusting and leveling bolt as a part of the top load plate assembly.

The housings also provide a constant free and operating height to facilitate installation. Rubber to Metal Bonded Anti Vibration MountsĮasyflex Model EFRSI Seismic Control Restrained Spring Vibration Isolators consist of free-standing, large diameter, laterally stable steel springs assembled into welded steel housing assemblies fabricated to limit vertical movement of the isolated equipment if equipment loads are reduced or if the equipment is subjected to large external forces such as a seismic events.

Twin Sphere Flexible Bellow with Floating Flanges.

Springs are galvanised & not painted for better rust protection. Vibration Isolators are provided with slotted mounting holes on base for bolting to floor.Ĭast Iron spring mounts can also be supplied with flattop or non skid neoprene top load surface in case of internal adjustment. The function of restrained spring mounts is to restrained spring action during the maintenance of Chiller or Cooling Towers.įeatures of Spring Mounts/Vibration Isolatorsīuilt in leveling device in all different types of Spring Mounts or Spring Vibration Isolators manufactured by AHI.Īnti skid elastomeric acoustical pad is standard with all AHI Spring mounts. The Restrained types of Spring Mounts are normally used for Chiller & Cooling towers for reducing the vibration. The function & Vibration Absorber by spring mounts will be better if you use higher deflection springs like 2' or 3'. The function of Spring Mounts is to absorb vibration & vibration related noise of rotating machines like fan, Air handling units, Pump & generators etc.

These Isolators consist of heavy duty steel springs Steel or cast iron housing.įunction & Application of Spring Mounts/Vibration Isolators Floor Mounted AHI is providing complete range of products like Housed type spring mounts for 1' deflection, Housed type Spring mounts for 2' deflection, Housed type Spring Mounts for 3' deflection, Open type (Unhoused) spring mounts for 1' & 2' deflection, Spring mounts for Inertia base, Rubber cup spring mounts, Restrained Spring mounts for 1', 2' & 3' deflection.
