Shannon GES Acoustic Blankets are a CAD designed/CNC produced, high quality engineered removable/reusable insulation system designed to reduce problematic noise, minimize maintenance, improve the surrounding work environment, withstand extreme weather and environmental conditions. Blanket design is CUI: Corrosion Under Insulation Compliant, Hydrophobic, Water Resistant & Corrosion Resistant.
Common Applications and Markets
Compressor Systems, Housings, Motors, Blowers, Liquid Chillers, Gear Boxes, Valves, Piping and Fittings, Pump Housings and Fan Housings. Noisy complex surfaces difficult to treat otherwise. Surfaces that require service, inspection and repair.
Service Temperature: Up to 450˚F (232˚C).
Acoustic Performance: 4 – 15 DBA Reduction Overall
Finished Surface Mass: 1.7lb/ft²(8.3kg/m²)-3.7lb/ft² (18.1kg/m²)
Product Components: Outer/Inner Jacketing – 16.5oz/yd² (560g/m²) PTFE Teflon® Impregnated Fiberglass Cloth. Mass Loaded Vinyl “Reflector” – 1.0lb/ft² (4.9kg/m2) or 2.0lb/ft² (9.8kg/m²). The Insulation Core consists of a double layer of plain needled fiberglass mat and Hydrophobic Supermat™ @ 9 pcf (176.2 kg/m3) Type “E” Fiber, encapsulated by the inner and outer jacketing, with a double sewn lock stitch construction, producing a “Self-Contained system”. The Blanket System includes Integral Fasteners for install & removal.
Blanket Thickness Surface Temperature Reference
* The above referenced Cold Face Surface Temperatures should be used as guidelines for blanket insulation thickness design.
* The Cold Face Surface Temperature of the blanket should approach surrounding ambient temperature conditions.
* The economic thickness of the blanket should consider blanket cost, thermal performance and blanket design constraints.
* Heat Loss Calculations are based on a 21.1˚ C (70˚ F) ambient temperature using a flat surface condition.
* The above referenced Acoustic Performance should be used as a guideline for blanket insulation thickness design.
* The Acoustic Performance of the blanket should be bench marked against the ambient noise condition.
* The economic thickness of the blanket should be considered in selection of a target reduction with consideration to blanket design constraints.
* Contact Shannon for guidance in selection, as the historical performance of each application varies significantly.
