Frequently Asked Questions

Common queries about structural damping, pneumatic isolation, and exhaust silencing for heavy turbocompressors.

What is modal analysis and why is it used for damping design?

Modal analysis identifies the natural frequencies and mode shapes of a structure. We use it to target the specific resonant peaks excited by a turbocompressor, then tune our damping sheets or isolators to those frequencies. This ensures the solution addresses the actual vibration problem rather than applying a generic product.

How do HD-Elastomeric Damping Sheets reduce vibration?

Each sheet consists of a viscoelastic core bonded between steel facings. When the structure vibrates, the core undergoes shear deformation, converting mechanical energy into heat. This constrained-layer damping can reduce resonant amplitudes by up to 60% on steel and concrete foundations. The sheets are adhered with structural epoxy and mechanically fastened at edges — no welding required.

What load range does the PVI-200 pneumatic isolator cover?

The PVI-200 supports loads from 500 kg to 5000 kg per isolator. It uses a nitrogen-charged rubber bellows to achieve natural frequencies as low as 2.5 Hz, providing 95% isolation efficiency for rotating equipment in the 5–50 Hz excitation range. Each unit includes a height control valve and an internal snubber for transient events.

Can the ES-900 silencer handle high-temperature exhaust?

Yes. The ES-900 series is rated for continuous operation up to 450°C. The housing is carbon steel with an epoxy coating, and the internal mineral wool packing is retained by stainless steel mesh. Flanged connections match ANSI 150# or 300# standards. Each unit comes with a pressure drop calculation report.

Do you provide installation support for these products?

We supply detailed installation manuals with every order. For complex projects — such as retrofitting damping sheets on an existing compressor skid or integrating isolators with a new foundation — our engineers can provide on-site supervision. Contact us with your project details to discuss support options.

Structural Damping & Isolation Capabilities

Engineered solutions for turbocompressor resonance control — from damping sheets to hybrid silencers, each system is tuned via modal analysis to match your equipment’s natural frequencies.

HD-Elastomeric Damping Sheet Series 400

High-density viscoelastic sheets bonded to steel or concrete substrates reduce resonant vibration amplitudes by up to 60%. Each sheet is constrained-layer damped and tested for loss factor before shipment.

Targeted frequency suppression without welding

Pneumatic Vibration Isolator Type PVI-200

Nitrogen-charged air springs achieve natural frequencies as low as 2.5 Hz, isolating turbocompressors, blowers, and pumps from harmonic excitation in the 5–50 Hz range. Height control valve maintains level under varying loads.

95% isolation efficiency for rotating machinery

Industrial Exhaust Silencer Series ES-900

Reactive-dissipative hybrid silencers tuned via modal analysis of connected piping. Attenuates broadband noise from compressor blow-off lines with 25–40 dB insertion loss across 63 Hz to 8 kHz.

Custom-tuned for tonal peaks without excessive backpressure

Modal Analysis & Field Survey

On-site measurement of structural natural frequencies, mode shapes, and damping ratios using accelerometers and impact hammers. Results feed directly into damping sheet placement and isolator sizing.

Data-driven design — no guesswork

Retrofit Damping for Existing Foundations

Add damping to compressor pedestals, turbine decks, and fan supports without demolishing concrete. Sheets are adhered with structural epoxy and mechanically fastened at edges — minimal downtime.

Upgrade existing structures in under 48 hours

Combined Isolation & Damping Packages

Integrate pneumatic isolators with damping sheets for a complete solution: isolators block low-frequency transmission, damping sheets suppress residual structural resonance. Single-source engineering and installation.
