ALJ-04 Spring Vibration Isolators consist of free-standing, large diameter, laterally stable steel springs assembled into welded steel housing assemblies. The housings are 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 high winds or seismic events. The housings also provide a constant free and operating height to facilitate installation.
Designed for the isolation of vibration produced by equipment carrying a large fluid load which may be drained, such as boilers and chillers, and for the isolation of cooling towers, air-cooled condensers, etc., where motion due to wind loads must be minimized.
ALJ-04 spring vibration isolator is a high-performance spring isolation device featuring a 50 mm static deflection. Compared with the ALJ-17 spring vibration isolator with a 25 mm deflection, the ALJ-04 provides a significantly lower natural frequency and superior vibration isolation performance.
