Coil support pan for an air handling unit

The invention relates to a basepan for a fan coil unit having spaced apart top and bottom walls formed from a plastic material and having an insulating material disposed therebetween. The top wall defines a coil support and condensate collection structure. A support pan for a heat exchange coil in an air handling unit includes a top wall made from a polymeric/co-polymeric material. The top wall includes an outer periphery and defines a coil support region and a condensate collecting region. A bottom wall is substantially co-extensive with the top wall and has an outer periphery substantially coincident with that of the top wall. Peripheral support channels structurally engages the outer peripheries of the top wall and the bottom wall and supports the walls in substantially parallel spaced relationship with one another to define a confined space therebetween. The coil support region of the top wall includes a plurality of parallel coil support segments. Each of the support segments defines an upwardly facing support surface configured to contact and support a lower end of a coil at a predetermined elevation. The support segments are spaced from one another by a plurality of condensate collecting channels which are at an elevation lower than the predetermined elevation. The condensate collecting channels are in fluid communication with the condensate collecting region, which is at an elevation lower than that of the condensate collecting channels. An insulating material, preferably polyurethane, is disposed within the confined space between the top and bottom walls.
