  • The imposed static load of the machine
  • The dynamic loads generated by the machine
  • The required vibration isolation performance criterias

CDM-MACHINE-MONT

CDM-MACHINE-MONT is a concrete inertia base system for machines designed to minimize vibration transmitted from a machine to its support.

System Features:

  • Quick and easy to install
  • Can be used to support most basic inertia thicknesses
  • Elastomer or spring mounts can be used, providing natural frequencies from 3Hz up to
  • Elastomer or spring mounts can be replaced after installation
he design of the CDM-MACHINE-MONT will be carried out by CDM engineers using the following information:
  • Weight and dimensions of the inertia base
  • Weight, dimensions and location of the machine supported on the inertia base and distribution of that weight

  • The dynamic loads generated by the machine
  • The required vibration isolation performance criteria or natural frequency specification

CDM-MACHINE-FIX

CDM-MACHINE-FIX are elastomer or spring isolation supports for machines designed to minimize vibration transmitted from a machine to its support.

System Features:

  • Quick and easy to install
  • Can be used to support all types of machines
  • Elastomer bearings and metal springs can be used depending on the desired natural frequency or isolation criteria
The design of the CDM-MACHINE-FIX will be carried out by CDM engineers using the following information:
  • Weight and size of the machine to be supported on the CDM-MACHINE-FIX supports and the load distribution on the different support points, if available

  • The dynamic loads generated by the machine
  • The required vibration isolation performance criteria or natural frequency specification

CDM-MACHINE-PAD

CDM-MACHINE-PAD isolation mounts offer simple and cost-effective vibration and impact isolation for a wide range of machines such as compressors, pumps, air handling and refrigeration units, etc.

System Features: 

  • Quick and easy to install
  • Can be used to support most types of machines
  • Elastomer bearings or strips or metal springs can be used to provide the necessary support
  • The type of support can be chosen according to chemical and biological exposure
  • Frequency can be adjusted for expected performance
The CDM-MACHINE-PAD support design will be carried out by CDM engineers using the following data:
  • Distribution of weight and load of the machine to be supported on the CDM-MACHINE-PAD supports
  • Size and layout of support surfaces
  • The dynamic loads generated by the machine
  • Dimensional limits
  • The required vibration isolation performance or natural frequency of the solution
  • Special requirements (temperature, oil, etc.)

CDM-AIR

CDM-AIR isolation systems are intended for the isolation of very low frequent vibrations, normally generated in industrial applications, such as foundry molding systems, textile machines, vibrating machines, etc.

System Features:

  • Very low natural frequency (<3 Hz)
  • Frequency can be adjusted for expected performance
  • Frictionless movement
  • Possible height adjustment
  • Wide range of CDM-AIR systems available to handle different loads
CDM-AIR support design will be carried out by CDM engineers using the following data:
  • Distribution of weight and load of the machine to be supported on the CDM-AIR supports
  • Space available for CDM-AIR supports (surface and height)
  • Machine excitation frequency to be supported
  • The required vibration isolation performance or natural frequency of the solution
  • Specific conditions

CDM MACHINE SUSPENSION

CDM-MACHINE-SUSPENSION solutions are used to resiliently fix all types of mechanical equipment, pipes and ducts suspended from the building structure. Providing suspension elements that effectively isolate noise and vibration significantly reduces the amount of noise and vibration transmitted from the structure to the building.

System Features:

  • Quick and easy to install
  • It can be designed to support pipes, ducts, mechanical equipment, etc.
  • Custom hangers can be manufactured to meet specific load and natural frequency requirements upon request
To design and specify the required CDM-MACHINE-SUSPENSION hanger, CDM engineers will need the following information:

  • Weight of the supported machine, pipe or conduit
  • The required vibration isolation performance or natural frequency of the solution
