Designing a commercial HVAC chiller system is no longer just about capacity, efficiency, and footprint. For many projects, the ability to meet local noise ordinances has become a critical design constraint that influences equipment selection, placement, and overall project cost.

Successful designs start with the right base information: equipment sound power levels, operating modes, property line setbacks, rooftop or grade-level installation details, ambient conditions, and applicable local noise ordinances.

Many municipalities now require nighttime sound levels of 55 dBA or less at adjacent property lines, making early acoustic planning essential for any mechanical engineer.

Raincloud NV's HUSHCORE® Chiller Noise Control Solutions provide multiple options on the path to compliance:

• STANDARD SC – Economical removable sound jacket treatment capable of reducing equipment sound power levels by 5 dBA.• UNITARY SM-SB – Custom fan attenuation systems tailored to meet site specific needs to ensure chiller noise levels are compliant with both daytime and evening ordinance sound pressure levels.• PREMIUM OF – Flexible outdoor grade acoustic curtain panels, that when applied to chain link fences or other types of open barriers, can create a cost effective enclosure around the equipment.

When applied in conjunction with one another, these solutions can help designers, consultants, and owners achieve ordinance compliance while avoiding oversized solutions, costly redesigns, or community complaints.


The best time to address chiller noise is before the equipment is purchased.
