Low Temperature - Hot Water & Chilled Water Blankets



Shannon Thermal Blanket Insulation is a CAD designed, CNC produced, high quality pre-engineered insulation system designed to save energy, capture radiant heat, minimize insulation maintenance and improve the surrounding work environment. Shannon Thermal Blanket is capable of withstanding severe indoor and outdoor environments. Shannon Thermal Blanket is flexible, easy to install, remove and reinstall, allowing quick access and easy equipment serviceability. The key benefit is re-usability.

Valves, Flanges, Pumps, Instrumentation, Fittings, Equipment and Equipment Heads. Complex geometry that otherwise would not see insulation as a result of service, inspection and repair.

Institutional, Commercial, University & Healthcare.

Service Temperature/Condition
Steam & Hot Water This design is to act as a Thermal Barrier with a maximum service temperature of 200˚F (93.3˚C).

Product Components
The Outer and Inner Jacketing is a 10.0 oz/yd² (339 g/m²) Vinyl Laminated Polyester Cloth. The Insulation Core consists of a 5.0 lb/CF (80.1 kg/m³ ) Owens Corning Utilicore® HP5 Fiberglass Mat will be encapsulated by the inner and outer jacketing, with a double sewn construction, producing a Self-Contained Blanket Insulation System. The Blanket System includes Integral Fasteners for install & removal.

* 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.
