UTA-Protect® is an integral shielding acoustic device specially designed and manufactured by SILTE to soundproof refrigeration units, heat pumps, industrial chillers and water cooling towers. UTA-Protect® is made to measure and configured for the specific system to be insulated; it is an acoustic device defined as ‘transparent to the passage of air and opaque to the passage of noise’; for this reason its presence does not hinder the correct operation of the system thanks to very low pressure drops <15 Pa.
UTA-Protect® offers average acoustic insulation of -15 dB(A) and up to -28 dB(A) at medium and high frequencies (performance certified according to ISO 11546-2).
The supporting frame and infill panels are made of anodised aluminium up to medium sizes, for larger systems the supporting frame is made of hot-dip galvanised steel. The panelling can be painted in a colour of the customer's choice at an additional charge. The acoustic cladding is realised with sound-absorbing sheathing with a mass of more than 5 kg/sq.m. alternating with sound-absorbing mats with differentiated density in thickness to improve sound absorption over a wide frequency range. The materials used are suitable for outdoor installation and are all eco-friendly. The panels are easily removable to allow for maintenance and inspection of the system.
The shielding incorporates silenced and correctly sized air passages. A special compartmentalisation system called AFT (Air Flow Tutor) prevents any possibility of short circuiting air flows.
UTA-Protect® models differ according to the position and number of fans on the machine:
- F series distinguishes shields designed for machines with frontal fans
- S series distinguishes shields designed for machines with top fans
