HIGH TEMPERATURE THERMAL HEAT SHIELD – SANITARY
HS1200FF-W (HS649C-FF-W)
INTRODUCTION
Shannon Thermal Heat Shield Insulation is a Self-Contained, CAD designed, CNC produced, high quality engineered insulation system designed to save energy, retain radiant heat, minimize insulation maintenance and improve the surrounding work environment. Shannon Thermal Heat Shield Insulation is non-porous, weather and chemical resistant. Shannon Heat Shield is flexible, easy to install, remove and reinstall allowing easy service. The key benefit is re-usability
Common Applications and Markets
Process Markets: Shannon Heat Shield Applications include; WASH-DOWN/SANITARY, Ovens, Kettles, Vessels, Equipment Heads, Pumps, Piping, Valves.
Service Temperature/Condition
This design is to act as a Thermal Barrier with a maximum service temperature of 1200˚F (649˚C).
Blanket Components
The Outer Jacketing consists of a layer of Stainless Steel Type 304 Sheet Foil .002” (.05mm) thickness. The inner jacket consists of a layer of Stainless Steel Type 304 Sheet Foil .002” (.05mm) thickness. The Insulation Material is an 11 lb/ft3 (176.2 kg/m3 ) Fiberglass Needled Mat – Type E Fiber and or a 7.5 lb/ft3 (120.1 kg/m3 ) density, Non-Woven Manniglass® fiberglass. The insulation filler is encapsulated by inner and outer stainless steel sheet foil, spot welded together, producing a selfcontained blanket system. The Shannon Thermal Heat Shield Insulation will include an integral fastener for easy install and removal.

* The above referenced Cold Face Surface Temperatures should be used as guidelines for Blanket/Heat Shield insulation thickness design.
* The Cold Face Surface Temperature of the Blanket/Heat Shield should approach surrounding ambient temperature conditions.
* The economic thickness of the Blanket/Heat Shield should consider Blanket/Heat Shield cost, thermal performance and Blanket/Heat Shield design constraints.
