Patent ID: 7559343

Claim:
An insulation module for a process vessel having a sidewall, said process vessel for containing a material to be maintained within controlled temperature limits for use in a process, said insulation module comprising: an outer surface layer; a thermal insulation layer attached to said outer surface layer and opposing a portion of said sidewall of said process vessel; a plurality of first fasteners extending between said outer surface layer and said thermal insulation layer for attaching said thermal insulation layer to said outer surface layer; a plurality of brackets extending from said outer surface layer to said sidewall of said process vessel, said brackets being securable directly to said sidewall; and a plurality of second fasteners extending between said outer surface layer and said brackets for attaching said outer surface layer to said sidewall of said process vessel, said thermal insulation layer being positioned at a distance from said sidewall by said brackets and thereby defining an air gap between said thermal insulation layer and said sidewall.
