Acoustic solutions for cooling units and chillers

For the acoustic insulation of chillers and cooling units, Fonois provides a comprehensive range of high-performance modular solutions. SH Pod casings, available in the standard version as well as in the SH Pod Advanced Chiller and SH Pod Advanced VRF variants, deliver effective noise attenuation while maintaining a compact footprint. Acoustic barriers shield emissions directed toward sensitive areas, while acoustic silencers and aphonic grilles ensure optimal airflow and maintain low sound pressure levels.

The benefits of soundproofing cooling units and chillers

The chiller, or cooling unit, is a widely used machine in modern urban settings, across residential, commercial, and industrial environments. There are countless applications for room cooling, refrigeration systems, and temperature-controlled production cycles. The operating principle of the chiller requires high fan capacities in the air-cooled version, while the water-cooled version uses large volumes of fluid. Equipped with fans, pumps, and compressors, chillers can be a significant source of noise.

For this reason, soundproofing of refrigeration motors is often essential, particularly in sensitive environments such as residential or healthcare settings.

Why choose Fonois acoustic solutions

Fonois is the soundproofing system designed to reduce noise emissions from chillers and cooling units, without compromising cooling and ventilation performance, even when using low-pressure fans.

Thanks to Slim Hurdle™ technology, all silenced systems, from the advanced SH Pod sound-absorbing casings to the discharge silencers, ensure exceptionally low pressure drop, typically around 10 Pa. In addition to acoustic insulation, SH Pod systems offer effective protection against environmental factors, including:

  • Solar radiation, enhancing thermal efficiency during summer operation and reducing energy consumption
  • Hail, protecting vulnerable coils and heat exchangers from mechanical damage

The soundproofing of refrigeration units, as required by the Framework Law 447/95 (Legge Quadro 447/95) and the DPCM 14/11/97, is essential to limit noise propagation towards sensitive areas. Fonois solutions ensure compliance with regulatory thresholds while preserving the chiller’s cooling and ventilation performance.
