FOOD GRADE / SANITARY PROCESS BLANKETS
LT550-CFH7-FG (LT288C-CFH7-FG)
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 weather and chemical resistant. Shannon Thermal Blankets are flexible and easy to install, remove and reinstall allowing quick access and easy equipment serviceability. The key benefit is re-usability.
Applications:
Food Grade and Sanitary Fittings & Equipment, Gate, Globe, PRV, Valves, Strainers, Flanges, Pumps, Instrumentation, Heat Exchangers, Complex “HOT” Surfaces that otherwise are left untreated. Markets: Food Processing, Pharmaceutical, Manufacturing .
Markets:
Food Processing, Pharmaceutical, Manufacturing
Maximum Service Temperature:
This design is to act as a Thermal Barrier with a maximum service temperature of 288˚C (550˚F).
Product Components
Outer Jacketing and Inner Jacketing is a 237 g/m² (7.0oz/yd²), PTFE Cross Film Laminate Fiberglass Reinforced. Insulation Core is a 176.2 kg/m3 (11 lb/CF) E-Mat, Fiberglass Needled Mat – Type E Fiber. Fiberglass Mat is encapsulated by PTFE Jacketing and double sewn together, producing a Self-Contained Blanket System (Non-Porous & Chemical Resistant). Shannon Blanket System includes integral fasteners for easy re-installation & 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.
