A condensate retaining apparatus for use with a refrigeration heat exchanger having at least two plannar slabs mounted in an air duct. Each slab has an upper and lower end and forms an oblique angle with respect to the direction of air flow and further includes a coil for conducting a fluid and a plurality of form defining channels for conducting condensate toward the lower end of the slab. The slabs are mounted so that the lower end of each overlying slab is offset inwardly from the upper end of the nearest underlying slab with each pair of adjacent slab ends defining an apex of the heat exchanger. The apex is covered to prevent condensate from being entrained in that air flow and as well as being shielded from the air flow.

Heat exchanger slab assembly having improved condensate retaining

An integrally threaded brass insert is molded into the discharge conduit of a condensate pan such that a steel drainage pipe can be threadably engaged to the insert without causing damage to the plastic discharge conduit. Bonding between the insert and the surrounding conduit is enhanced by providing a knurled surface on the outer periphery of the insert.
