ABSTRACT:
A substantially torus-shaped chamber is refurbished by installing partitions about the chamber to create isolated compartments within the chamber, and by sandblasting, painting, and curing the paint in the compartments and exhausting air from the compartments so that the dust and fumes from the compartments are not spread to adjacent ones of the compartments. In the curing process a plurality of insulated panels are installed in juxtaposed relationship with respect to the painted surfaces, and high velocity air is moved between the panels and the painted surfaces in closed paths. The recirculating air is heated to approximately 200.degree. F. and the hot air is confined substantially to the space immediately adjacent the painted surface. A conduit system is formed about the perimeter of the insulated panels, and fluid, such as ambient air, is drawn through the conduit system in contact with the painted surface so as to form a heat sink at the perimeter of the insulated panels, to extract heat from the painted surface and prevent heat from spreading from the compartments being dried to the adjacent compartments.
