       11 . The casing assembly of  claim 10 , wherein the first panel of the wrapper further comprises a first top portion opposite the first surface and including a first folded lip, the second panel further comprises a second top portion opposite the second surface and including a second folded lip, and the third panel further comprises a third top portion opposite the third surface and including a third folded lip.  
   
   
       12 . The casing assembly of  claim 11 , and further comprising: 
 a upper angle extending between the first top portion of the first panel and the third top portion of the third panel.    
   
   
       13 . The casing assembly of  claim 10 , wherein the wrapper is formed from a single sheet of material.  
   
   
       14 . The casing assembly of  claim 10 , wherein the first surface of the first panel of the wrapper is oriented about 90° from the second surface, and the second surface is oriented about 90° from the third surface.  
   
   
       15 . The casing assembly of  claim 10 , and wherein the wrapper further comprises: 
 a first flange extending from the first bottom portion of the first panel;    a second flange extending from the second bottom portion of the second panel; and    a third flange extending from the third bottom portion of the third panel, wherein the first, second, and third flanges define a shelf configured to support a condensate pan.    
   
   
       16 . A wrapper suitable for use in a heat exchange assembly, the wrapper comprising:
