Details

Please Contact Tim Dudley @ 804-709-1954 or Carl Schmitt @ (804) 475-0676

The room is constructed of prefabricated, insulated panel sections. The exterior surfaces of the chamber will be stucco white galvalume. The room interiors will be 20 gauge Series 304 #4 finish stainless steel. Ceiling and wall panels are joined to each other with cam locks. All cam lock and threaded rod access ports are located on the exterior of the chamber, except when exterior access restrictions require internal cam locks.

• Full product specifications and drawings available upon request.
• New Cost (not including installation and inspection) $375,000.
• These units were purchased for a project that was cancelled before they were delivered.
• There are no photos of the actual assembled units because they were shipped from the factory and put directly into storage.
• Please note - Each room is intended to be electrically/mechanically independent, but share common walls between adjacent rooms.
