The details are sorted in alphabetical order by product model name. Problem: Reinforcement and doweling in of the housekeeping pad to the structure is often overlooked. For concrete attachments, this requires ICC-ES certified anchors. The details can be easily imported into your specification documents or plans. Solution: All connections of the restrained spring isolators must be designed for these loads. Kinetics Middle East is proud to offer details of our products in AutoCAD, Revit (BIM) and PDF format. Spring Vibration Isolator Seismic Restrained Vibrasystems. Solution: Flexible connectors are required to reduce equipment nozzle loads.Product Details in BIM (REVIT), AutoCAD (DWG) and PDF Downloads Typical isolated equipment include: pumps, fans, cooling towers, rooftop equipment, chillers, boilers, and compressors. Problem: Differential motion due to equipment on isolators and piping attached to structure. Kinetics spring vibration isolators are used to reduce the transmission of noise, shock, and vibration produced by mechanical, industrial or process equipment into or within a building structure. Solution: Omega Naught Factor (Horizontal forces multiplied by 2.5). Problem: Poor installation of concrete anchors. Solution: All connections must be checked including anchorage of unit to base or isolators, attachment of base to isolators and isolators to structure. KINETICS FRS Restrained Spring Isolators Kinetics Model FRS vibration isolators consist of free-standing, large diameter, stable steel springs assembled into top and bottom load plate assemblies, which provide vertical restraint in the event load is removed or external forces are applied. Problem: The complete load path from the center of gravity of the unit to the structure is not always considered. Solution: Restrained springs must be used and a certain number of springs may be required to distribute the load properly to the structure. The seismic isolators are used where vertical restraint is required along with external forces. Typically wind forces are higher than seismic, excluding high seismic areas like California. Products Vibration Isolation Floor Mounted Restrained Spring Restrained Spring Vibro-Acoustics Restrained Spring (CSR) series provide vibration isolation for mechanical systems and equipment. Springs are made from high quality and heavy spring steel. Problem: Horizontal and vertical forces due to wind and/or seismic forces applied at the center-of-gravity of the unit require proper design of the attachment of the unit and/or vibration isolators to the structure. ![]() Solution: Certified anchorage calculations must be submitted to verify loading conditions are met for each piece of equipment. ![]() Seismic/Wind Requirements Problem: Forces are determined by a number of factors including: project location, site class, risk category, component importance factor and equipment location equipment relative to the overall height of the building. Restrained spring isolators are provided with leveling bolts that can be used for blocking during equipment installation. These assemblies are designed for vertical and horizontal motion restraint. Solution: Restrained isolators with upward limit stops must be used to keep unit from becoming displaced and damaging piping connections. Restrained spring isolators consist of laterally stable, free-standing springs assembled in a steel housing. Weight Issues Problem: Unit must be drained for cleaning at required intervals. Problem: Some Cooling Towers are not designed to be point loaded on isolators. Vibrasystems isolators are tested and certified to ASHRAE 171-2017 for wind and seismic load resistance using cyclic loading in multiple directions. Proper calculations should be performed for quantity and locations of the hangers. SRMT/F series are heavy-duty seismic restrained spring mounts with unique sliding channels designed to withstand lateral loads in combination with vertical loads. Depending on pipe size, this set-up usually requires 3 to 5 hangers on either side. Spring hangers or restrained spring isolators are recommended on the inlet and discharge piping until the vibration is dissipated. A minimum of 2-inch deflection is suggested so that the springs are operating at a high efficiency. Due to the potential change in the operating weight of the cooling tower, restrained isolators are recommended. Unlike airborne noise, structure-borne noise is very difficult to diagnose post design. ![]() Vibration from the fans is transferred to the structure and can create noise problems in different areas of the building. Structure-Borne Vibration Problem: This is noise traveling through the structure instead of the air.
