MS and MSS Series Seismically Rated Isolators

Product Overview


Product Overview

Product Description, Applications

MS and MSS Series Isolators, designed to minimize code-required seismic loads on isolated equipment, are the newest generation of seismic mounts by the Vibration Mountings & Controls company of The VMC Group. Manufactured using robotic welders, MS and MSS Series Isolators are open spring mountings with welded, seismically-rated steel housings. MS Series Isolators have an internal spring adjustment; MSS Series Isolators have an external adjustment bolt that acts as a single point attachment to the equipment. Both help limit horizontal equipment motion from wind or seismic load to 1/4" (6.35 mm). They are available with 1" (25.4 mm) and 2" (50.8 mm) deflection springs and have a load range from 50 lb to 6500 lb (23 to 2948 kg).

Designed for installation in concrete or steel, applications include:

  • HVAC equipment and fan assemblies
  • General industrial equipment
  • General industrial equipment
  • Pumps, chillers and cooling towers
  • Condensing units
  • Generator sets
