Engines are used in a wide variety of applications other than road vehicles. These include boats, generators & mobile utilities to name but a few. Each application requires a solution that is designed to fit the unit and does not interfere with its operating conditions.

Ventac was approached by the Facilities Manager of Glanbia to reduce noise emissions from three chillers on the roof of the plant in Drogheda. Our expert acousticians advised on the installation of a 25 metre long x 3 metre high acoustic screen to reduce the pure tone noise from the chillers. The plant was overlooking several residential homes and the EPA were concerned about the amount of noise emanating from the chillers. Since our screen has been erected all local residents have been satisfied that these noise levels have dropped significantly.

Ventac completed this project in conjunction with AOBV in the Netherlands. Their Client was Mayekawa (Belgian Office). Mayekawa are a Japanese company that specialise in the manufacture of compressors for different types of gases. Our brief was to design, manufacture and install an acoustic lagging jacket to a screw compressor tank supplied by Mayekawa. From noise data collected a barrier jacket construction was selected to achieve the specified noise levels.

The Principal of Pobailscoil Ghaoith Dobhair in Donegal contacted Ventac to help solve the reverberation in the brand new General Purpose Hall. When we first met the Principal, the building was in the final stages of completion and we were able to carry out various noise tests to identify what the current reverberation time was. We found the reveerb time to be 4.6 seconds; well above the recommended rever time for this kind of room.

Ventac have developed a patent pending solution for road sweeping vehicles. Our challenge here was to design and produce a noise reduction solution for road sweeping vehicles. This presented many unique challenges. There are multiple noise sources to take into consideration including two diesel engines, a large centrifugal fan and the sweeper brushed themselves.

Sweeper manufacturers and operators face many noise and dust issues depending on the locations their machines are being used.

Ventac were awarded the contract to supply and install an acoustic solution to reduce the noise levels on the plant room floor of the factory in Dundalk, Co. Louth. Noise levels of 87dB were being read at the noise sensitive location. The noise was coming from their water chiller in the corner of the manufacturing floor. Ventac designed, manufactured and installed a flexible acoustic enclosure to reduce noise emissions to below 80 dB. This enclosure was held in place by a steel sub frame and sliding doors were also installed to allow for easy access to the chiller for maintenance purposes.

The proprietor of the Spar Shop in Shankill, Co Dublin approached Ventac to design a solution for a noise problem as a result of complaints he received from local residents. The noise was coming from the rear of his shop from condensers and fans used for chilling fridges in the retail unit. The tonal noise was an issue for his neighbours. Ventac supplied and installed a 7m long x 2.5m high Acoustic Screen to reduce this noise to an acceptable level. Once this screen was erected the noise levels were indeed reduced the nearby residents were happy that the problem had been resolved.

Ventac were approached by the Principal of this school to carry out a noise survey of the GP Hall to determine the reverberation time in the hall. Results showed this to be well above permissible limits and, as such, the principal then asked us to design a solution that would bring the noise levels down to the required RT time. Our expert installation crew were able to design and install foam and fabric treatment to the GP Hall which gave the room an excellent look as well as an excellent sound. Ventac provided a solution that not only reduced the reverberation time to within the required limits but also provided an overall finish and appearance that the school were very pleased with.

Ventac were awarded the contract by Proctor and Gamble to reduce the noise emissions from their Boucherie machines at the factory in Carlow. These machines were already enclosed but noise was still penetrating and causing annoyance to employees on the plant floor. We found that these machines had several noise sources with different frequencies, i.e. airborne noise, motor noise and metal on metal noise.

We chose to install a large amount of Open Cell Acoustic Class 'O' Fire Rated Foam to reduce the internal reverberation time. This foam was applied to all areas of the internal machine, ceiling, walls and doors. To stop noise penetrating through gaps in the machine, we installed acoustic seals to these areas. This solution was extremely successful and five other similar machines were upgraded with this treatment.

The Railway Procurement Agency (RPA) awarded Ventac the contract to supply and install 57 metres of barrier along the Luas rail line in Beechwood, Ranelagh. The barrier is 3 metres in height and made of timber. Most of these works were carried out at night so as not to interfere with the Luas timetable. The RPA had received several complaints from residents living along that line. After the installation of the acoustic sound barrier, the residents were satisfied that the noise had now been reduced to an acceptable level.
