Dual wall evaporator pan

An evaporator pan assembly comprising an inner pan having a bottom wall, side walls and end walls joined together to form a pan having an open upper side, a laterally outwardly projecting continuous flange contiguous with the sides and one end of the inner pan, an outer pan having sides and ends with upper edges, means for joining the upper edges of the sides and one end of the outer pan in a fluid-tight seal to the outer margins of the continuous flange, means for providing a fluid-tight connection between the side walls of the outer pan and the other end of the inner pan, and at least two drain openings and an overflow opening through said other end of the inner pan.

An evaporator pan assembly comprising a plastic inner pan, a plastic outer pan, the plastic inner pan having side and bottom walls, and the plastic outer pan having side and bottom walls spaced outwardly from the side and bottom walls of the inner pan and joined at their upper extremes to the upper extremes of the side and inner walls of the inner pan, the side walls of the inner pan being inwardly inclined toward the bottom wall, and flat sections on the inner pan side walls, the flat sections being parallel to one another and being spaced apart by a distance about equal to the width of the lower portion of an evaporator for receiving said evaporator lower portion between the wall sections.

An evaporator pan assembly comprising:

• an inner pan having side walls and a bottom and an open top defining a pan capable of containing water;
• an outer pan having side walls and a bottom surrounding the bottom and all but one of the side walls of the inner pan and spaced therefrom leaving the one side wall of the inner pan uncovered by the outer pan and having an open top whereby an evaporator can be introduced through the open top into the area between the side walls of the inner pan, the space between the inner pan and the outer pan defining an air space, and means for rendering the air space fluid tight.
