CHILLER SOUND CONTROL IN SENSITIVE SETTINGS

Planned in the heart of Boston’s historic Back Bay neighborhood for a 160+ year old mill building were (3) new chillers expected to exceed local noise codes upon start up. BRD Noise & Vibration Control was brought on by the project acoustician during the planning stage, and tasked with providing a free-standing solution to meet the target dB(A) goals along with minimal pressure drop impact.

Upon completion of an engineering site visit, BRD designed, built and delivered a PE-rated Unitary-IM-SB System™ Independently Mounted to the chiller platform, with a Silencer Bank suspended above the chiller deck to address the condenser fan exhaust and noise output at the source.

Pictured to the left is a close-up image of the PE-rated baseplate connection used to facilitate the independent system frame.

HUSHCORE® PANELS & SILENCERS SUPPORTED BY STRUCTURAL STEEL FRAME

BRD silencers provided additional attenuation and limited fan discharge pressure drop to no more than 0.08” W.G., while exceeding target dB levels. Our Hushcore® Unitary-IM-SB System™ achieved 11 dB(A) reduction on average across the octave bands, performing particularly well at the high frequencies with up to 17 dB(A) reduction in the 1000hz band:

Unitary IM-SB (Insertion Loss)
BRD’s design met wind load requirements, and was PE stamped and approved – providing peace of mind and assurance behind the solution and its performance.
BRD FOREMAN SUPERVISION

In addition to install documents BRD provided onsite presence and a supervising foreman responsible for
direction and oversight of a successful completion of
the installation.
