Steel Housed with Top Plate
Acrefine ASI-T1 and ASI-T2 type seismic vibration isolators are designed to restrain lateral and vertical equipment movement caused by external forces such as high winds or seismic events. The isolator housing is fabricated from high quality welded steel. This design incorporates two restraining points that limit vertical and lateral movement of the equipment. The operational height of the isolator is fixed and any adjustment can be made via the adjustment nut located on top of the spring plate. Fixing holes are provided on the top plate for easy installation of equipment.
Vibration isolation is achieved by free-standing laterally-stable steel springs. All springs are assembled into elastomeric acoustical cups to eliminate internal noise. Springs are designed with 50% overload capacity and the lateral spring stiffness is greater than the vertical stiffness to assure seismic stability.
Acrefine ASI-T1 and ASI-T2 type seismic vibration isolators are designed for floor mounted equipment such as cooling towers, chillers and boilers. These isolators are ideally suited for applications where seismic or high wind forces are likely. Spring deflections of 50 mm (2″) provide excellent noise and vibration control.
ASI-T1 and ASI-T2 isolators are available 25 mm (1″) and 50 mm (2″) deflection as a standard. The load range is from 7 kg (15 lb) to 3110 kg (6858 lb). For higher deflection or load capacities please contact us.
