Polymer Technologies has led the innovation in noise control material solutions for power generation equipment. We have been working to design practical UL2200 Recognized acoustic materials to meet industry regulatory and commercial requirements of both large and small manufacturers. We provide solutions for units used in standby emergency backup power ranging in size from 2.5 kW to 2 mW. Additionally, Polymer has been working with companies in the alternative sectors such as wind turbines and battery powered devices.
Some considerations for selecting materials for enclosure applications are the mass of the enclosure and the spectrum of the noise sources to be considered. Critical to any design is the amount of the open area, the intake/exhaust, and how well it is baffled (line of sight elimination). The more open area in an enclosure than the less effective barrier and damping materials will be, and the more challenging to gain significant noise attenuation. All of these factors play a role in any power generation enclosure design and determine which products are best to use, if a Polydamp® acoustical foam is the most cost effective and technically appropriate solution, or if Polydamp® barrier composites or Polydamp® vibration damping material should be utilized. Polymer's power generation noise control experts can work with your engineers on site in a collaborative effort to determine which products would best serve your needs.
Doors, Service Hatches, & Intake/Exhaust Plenums
Polymer Technologies designs products and materials to help eliminate line of sight through plenums, louvers, through the use of absorptive and barrier materials. There are also doors and hatches for which materials need to be designed to help eliminate acoustical weak spots. In order to ensure proper sealing, gaskets are used to make sure there are no leaks for noise to escape.
When creating a design for the enclosure itself, enclosure panel weight plays a critical role in determining if you would use just an absorber or an absorber/barrier composite. Of course, the design’s noise reduction goals play a role in determining the proper power generation composite solution.
