ISOTECH®  IHSS Housed Seismic Spring Isolators are premium, seismically-rated floor-mounted isolators designed for effective vibration isolation of HVAC equipment in seismic or outdoor applications. Engineered for use with concrete inertial bases or steel support structures, these isolators feature a hot-dip galvanized steel housing that allows for anchor application and includes an integrated snubber, limiting movement to just 1/8” in all directions while providing a minimum of 1g lateral load resistance.

Each IHSS isolator is equipped with uniquely engineered springs offering 50% additional travel to solid, ensuring optimal performance. The springs are powder-coated and color-coded for corrosion resistance and easy identification, while all adjustment nuts and hardware are zinc-plated for durability. An all-directional elastomeric snubber prevents metal-to-metal contact, enhancing the system’s longevity.

Competitive Advantages: The IHSS model meets stringent HVAC application requirements with a minimum Kx/Ky ratio of 1 and 50% overtravel, making it ideal for height-restricted installations. Isotech’s innovative spring design allows for versatile side-to-side and nesting combinations, reducing inventory costs and increasing affordability.

With a high capacity of up to 3,500 lbs and a pre-compressed feature, the IHSS isolator streamlines installation while minimizing overall system height. Each unit includes a shipping block/spacer, serving as an indicator for perfect adjustment post-installation.

Constructed with high-yield steel for improved seismic resistance and maximum corrosion protection, the IHSS is the cost-effective choice for superior vibration isolation in seismic applications.
