SIAD Macchine Impianti, represented in Oceania by HBM Packaging & Plastics Technologies , have modified the Tempo range of PET-blowing compressors, to produce 75dB(A) at 1 metre in any direction. The new PET-blowing compressor is known as ‘the Silent Box’.
Sound reduction in the PET-blowing compressor is achieved through the use of an in built electrical soundproof cabin and in-out silenced air fan. The cabin is completely accessible for full maintenance and allows for quick and easy installation.
The ‘Silent Box’ package eliminates the need to build a special ‘sound proof’ service room which is typically used for high pressure compressor installations. The ‘Silent Box’ can also be retrofitted to existing SIAD installations.
The Tempo machines are three stage units, which deliver totally oil-free, dried high pressure (40bar) air, with outputs from 90 to 5,500 Nm³ per hour. The Tempo machines have large inlet filters that are silenced and firmly mounted on the compressor skid, with a dust filtration level of 3 microns. The machines are fitted with stainless steel piping to prevent oxide formation.
