Scroll Sound Shells

Emerson

Product: Insulation

Market: Energy HVAC

Refrigeration and HVAC equipment noise levels have become as important as carbon footprint, reliability or energy efficiency. This is particularly true for compressor packs on HVAC units that are often a source of disturbing noise in urban areas. Emerson decided to raise the stakes by going one step further and asking Vitalo to design sound shells that provide outstanding sound reduction benefits.

OEM key requirements:

  • Need to avoid the cost of acoustically insulating the full cooling unit
  • No impact on compressor operation or performance
  • Dual design: on-line mounting (new equipment) or on-site installation (retrofit)
  • Clean fit and nice finish

The Vitalo response:

  • -12dB(A) sound attenuation vs. 3 to 6 for competitive solutions
  • High density PU foam solution (low cost tooling / fast prototyping and testing)
  • Combining acoustic and thermal insulation
  • Increased surface resistivity
  • Complete set of different technologies supplied
  • Safety stock for fast deliveries
