HOT WATER & STEAM SYSTEMS

LT450SS (LT232C-SS)

INTRODUCTION

The 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.

Common Applications and Markets
Shannon Thermal Blanket Applications include: Gate, Globe, Ball, Butterfly, Control and Wafer Valves, Flanges, Pumps, Instrumentation, Equipment Heads, any and all complex surfaces. Shannon Thermal Blanket Markets include; Institutional, Commercial Steam & Hot Water users. Applications that require service, inspection and repair.

Service Temperature/Condition
Steam & Hot Water. This design is to act as a Thermal Barrier with a maximum service temperature of 450˚F (232˚C).

Product Components
The Outer and Inner Jacket is a 17.0oz/yd² (577g/m²) Silicone Impregnated Fiberglass Cloth. The Insulation Material is an 11lb/CF (176.2 kg/m3) Fiberglass Needled Mat Type E Fiber. The Fiberglass Mat is encapsulated by the Silicone Impregnated Fiberglass Cloth and sewn together, producing a Self-Contained Blanket System. The Shannon Thermal 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.
