Abstract: A condensation collection system including a housing, a heat-exchanging coil located in the housing, a drain pan located in the housing and underneath the heat-exchanging coil, a water-sensitive element located in the housing and underneath both the heat-exchanging coil and the drain pan. The drain pan is configured to collect condensation from an interior of the housing. The drain pan includes a bottom, three or more exterior walls that generally conform to an interior perimeter of the housing, a primary drain located on a first exterior wall selected from the three or more exterior walls, and a controlled overflow drain located on a second exterior wall selected from the three or more exterior walls. The primary drain is configured to drain collected condensation from the drain pan. The controlled overflow drain is configured to drain the collected condensation from the drain pan.

Abstract: An air handling unit, includes: an outer casing defining an air passage from a first opening on a first side of the outer casing to a second opening on a second side of the outer casing; a first supporting member in the air passage and affixed to the outer casing; a heat-exchanging coil affixed to a surface of the first supporting member facing the second opening; a second supporting member located such that the heat-exchanging coil is located between the first supporting member and the second supporting member; a first connection member connecting the first supporting member and the second supporting member; and insulation material adjacent to the outer casing at least between the first supporting member and the second opening, the insulation material being located between the first connection member and the outer casing, wherein the insulation material is unperforated between the first supporting member and the second opening.
