Contact Us Seismic Restrains Isolation System
 
  • device that limits lateral and vertical movements of mechanical equipment during earthquakes

  • ensure  equipment physical  integrity

  • ensure equipment operation after earthquakes

Features:

  • capacity : up to 48 000 pounds per isolator
  • may be added to existing facilities
  • mechanism integrated in standard vibration isolators
    or independent seismic limiting devices

 

Applications:

Industrial Noise Control
  • for floor or suspended equipment
  • piping seismic retention system…

     

 

Electronic Sound Masking Device

  • adds a more pleasant sound to the environment

  • assume uniform coverage of intruding disturbing noise

  • reduces distraction caused by disturbing noises

  • covers intruding office sounds, such as HVAC system, keyboard clicking,
    printers, light manufacturing noises

  • increase speech privacy in working environment, especially in open-plan offices

  • enhance the ability to concentrate, relax or sleep

  • reduce stress

  • adds sound in environments that are too quiet

Features:

  • One master unit covers a surface of up to 4 000 ft²
  • Easy in-between-ceiling installation
  • Little, if any, maintenance
  • Easy tuning
  • Volume levels can be adjusted individually

 

Applications:
  • Industrial, commercial, residential and educational applications

  • For restless sleepers, office professionals, shift workers, infants, apartment dwellers

  • In open-plan office, conference room, study room, library, medical clinic, legal office, hotel room

  • Dentists, counselors, therapists office…
     

 

Active Sound and Vibration Control (ASVAC)
  • electronic system that cancel disturbing noise in confined environments by creating an antinoise signal

  • improves acoustical environments

  • control low frequency noise  (less than 700 Hz) in Heating, Ventilation and Air Conditioning (HVAC) systems, in ducts carrying corrosive or high temperature fluids (like car engines, air compressor exhausts or hydraulic circuits) and heavy vehicle and airplane cabins

  • often used in concert with conventional dissipative

Features:

An active control system consist of:

  • an input microphone upstream to measure noise

  • a processor to analyse the noise and generate a contrary sound wave

  • a system composed of an amplifier and loudspeakers

  • and an error microphone downstream from the loudspeakers to pick up residual noise and signal the processor to adjust the antinoise signal

 

Applications:
  • attenuation of noise generated by rotating machine (roots exhauster, vacuum pump, diesel engine…)

  • ventilation system, compressor air intake, exhaust of generator, diesel engine, vacuum pump enclosure…
