Reusable acoustic blankets reduce chiller noise for college classes

reduce chiller noise

NORTH TONAWANDA, N.Y. – February 4, 2021 – Shannon Global Energy Solutions designed and manufactured reusable acoustic blankets for SUNY Oneonta to cover two compressors on a Trane Model RTAA Rotary Liquid Chiller and reduce chiller noise level affecting classes at the nearby Human Ecology Building.

Before covering the compressors with a set of Shannon LT250A-VP reusable acoustic blankets (which Shannon designs specifically for HVAC equipment such as liquid chillers) instructors were distracted by the operation of the chiller’s compressors and fans. Although elastomeric vibration eliminators can reduce structurally transmitted sound, the chiller’s uninsulated compressors disturbed instructors and students in class.

Shannon learned about the acoustic challenge with the chiller located near the Human Ecology Building while helping the college’s facilities team evaluate the use of Shannon reusable insulation blankets for a set of valves located in the campus’ tunnels.

“The SUNY team felt there wasn’t much they could do to reduce chiller noise,” said Terry Roach, major account manager for Shannon. “We looked at the situation and system; the compressors have some unique geometries, but we always find a way to accommodate that.

“We recommended the LT250A acoustic blanket,” Roach added.

“The blankets perform well; once Shannon made them and shipped them to us, we installed them ourselves, and they go on and come off easily,” said Terry Zimmer, director of Facilities Operations for SUNY Oneonta. “The sound is noticeably different, since putting the acoustic blankets on.”

According to Shannon, there has been a reduction in noise of 6 dBA since blanketing the compressors.
