Restrained Spring Isolator

Restrained Spring Isolator

Easyflex 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. The housings also provide a constant free and operating height to facilitate installation. 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. Holes are provided in all isolators for bolting to the structure and to the supported equipment. 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. EFRSI isolators are available with deflections upto 2" (50 mm) and with load capacities to 15750 kg. as standard products. Custom isolators with higher deflection and greater load capabilities are also available. 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. where motion due to wind loads must be minimized.
