Low Temp Thermal Process Blanket

LT450TT (LT232C-TT)

INTRODUCTION

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

Applications and Markets:
Shannon Thermal Blanket applications include; Valves, Flanges, Pumps, Instrumentation, Equipment Heads and it serves as an all purpose blanket. Shannon Thermal Blanket Markets include: Chemical and Petro Chemical Processing Plants.

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 16.5oz/yd² (560g/m²) PTFE Teflon® 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 PTFE Teflon ® Impregnated Fiberglass Cloth and sewn together, producing a Self Contained Blanket System. The Shannon Thermal Blanket 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.
