This Avantco 17819002 evaporator drain pan is a direct replacement for the one that came standard with Avantco ZPT, SS, and APT series refrigerated prep tables. The drain pan is a vital part of your unit, collecting runoff water and condensation so that it can be disposed of. This prevents it from pooling and damaging other internal components and inhibits the growth of mold, mildew, and bacteria. Be sure to fix a broken one promptly.
