“Glasco” is a well-established brand in glass processing with over 20 years of experience. The company works with modern technologies and machinery, continuously developing new markets, activities, and services. Its production facilities are located in the industrial zone of Targovishte.
When the client contacted Acoustic Force, the complaint was high noise from two fan turbines that are part of a glass tempering line at Glasko Ltd. The client asked for a site visit and for the best and most innovative way to solve the problem.
After the site visit, the Acoustic Force team found an effective and economical solution: a metal enclosure covering both turbines. The design was prepared by eng. Aleksandar Kirechev.
Following the on-site inspection and situation analysis, a custom technical project and a detailed report were prepared for the client, outlining the design and construction of a metal soundproof enclosure.
Acoustic Force was commissioned to develop the technology, while the installation of the facility was carried out by Ircon Ltd.
The two turbines are sources with a sound power level of about 120 dB(A) each. After the enclosure was installed we carried out control measurements at several points: directly in front of the enclosure’s silencers the level is 80 dB(A), and at the workstation 76 dB(A).
With 8 hours of work at this position, the daily exposure stays below the lower exposure action value of 80 dB(A) under Bulgarian Ordinance No. 6 of 2005 on noise at work.
In this way we helped the fan turbines reach normal operating temperatures, and the noise indicators now meet the regulatory requirements for the environment and the workplace.
