STS Isolamenti
Who we are
STS Isolamenti Srl is an Italian company with a long history of designing and manufacturing soundproofing solutions for industrial, residential, and technical applications. This consolidated experience in the acoustics sector has led to the creation of the FONOIS brand, specifically designed to provide modular, ready-to-use soundproofing systems for HVAC/R systems, including refrigeration units, chillers, heat pumps, and multipurpose units.
Who are our solutions intended for?
FONOIS solutions are aimed at:
- companies operating in commercial and industrial refrigeration;
- installers, designers and system integrators of HVAC/R systems;
- technical assistance centers and maintenance personnel who must manage noise and vibrations from refrigeration units, chillers, or heat pumps;
- operators of buildings sensitive to acoustic comfort (e.g. hospitals, schools, offices) where refrigeration equipment must be silenced without compromising its performance.
What we do
FONOIS offers a range of functional and innovative acoustic solutions for reducing noise produced by refrigeration machines and air handling systems, including:
- modular soundproofing enclosures for refrigeration units, chillers and multipurpose units;
- compact noise barriers designed to prevent the spread of noise emissions;
- acoustic booths for total isolation of sound sources;
- acoustic silencers and soundproof grilles to filter and reduce mechanical noise and turbulence associated with the operation of refrigeration components;
- “ready-to-use” products that are easy to install and designed to reduce noise impact without compromising the efficiency of the machines.
The advantages of our solutions
- Significant reduction in refrigeration system noise, contributing to environmental comfort and compliance with regulatory noise emission limits.
- Patented technologies such as Quiet Leaf™ and Slim Hurdle™ combine high sound-absorbing performance and reduced thickness to minimize space and pressure losses.
- Simple installation and easy maintenance thanks to modular and accessible products.
- Protecting machines from the elements and extending the life cycle of acoustic components.
- Possibility of adaptation to different system configurations and architectural or technical requirements.
Distribution and assistance
STS Isolamenti and the FONOIS brand operate throughout Italy, with headquarters in Turin, providing specialized technical support for selecting the most suitable products, consulting during the design phase, after-sales assistance, and operational support on construction sites.
Commitment to innovation and sustainability
The company invests in research and development to bring to market patented, high-performance, low-impact solutions for HVAC/R systems, improving not only acoustic comfort but also the overall efficiency and operational sustainability of refrigeration and air conditioning systems.
