11/23/2023 0 Comments Restrained spring isolatorsFor equipment installed on the roof tops the YRS-C isolators are best suited for resisting the strong wind load. Tomahawk's model YRS-C restrained isolators are recommended to be the vibration isolators for equipment that undergo large amount of fluid load changes during service or maintenance such as chillers, bilers and cooling towers. Springs are marine grade primer coated prior to another layer of color paint coat for easy load indetification and corrosion resestance. All the steel housing assemblies are hot-dipped galvanised for corrosion proof as standard feature while level adjustment bolts, limit stop studs, locking screw and washers are cadmium plated, adding further supreme weather-proofing. Bolting holes are provided in both the top load plates and bottom base plates. The spring elements are assembled with spring caps (YRS-C1 only) or mounting load plates, with spring caps/mounting load plates be level adjustable by level adjustment bolts/or nuts and neoprene spring cups. The steel housing assemblies limit vertical movements of the equipment under isolation by the travel limit stop studs and the top plate of the side support frames, through the center holes of both. Now it has been revised and refined in design and expanded in sizes simultaneously. of which the springs are free standing with srping outside diameter to loaded operating height ration of minimum 0.80 and additional 50% deflection to solid from rated deflection, with the additional welded steel housing assemblies to limit the vertical movements of the springs. 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.Tomahawk's YRS-C restrained vibration isolators are the outgrowths of Tomahawk's C-series springs. 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. Floor Lift Slab Mount – Spring (Jack Up – Spring)Įasyflex 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.Floor Lift Slab Mount – Rubber (Jack Up – Rubber).Stainless Steel Braided Pump Connectors With Flanges.Stainless Steel Braided Pump Connectors With Threaded Connections.Flexible Connector Fan Coil & AHUs Type EFFCUC.Stainless Steel Pump Connectors Type EFMHPC.Stainless Steel Braided Pump Connectors With Grooved Connections.
