Description
The Heatcraft Refrigeration 24703503 Drain Pan Heater is an electric resistance element placed along the bottom surface of a condensate collection tray to stop water from solidifying during sustained low-temperature operation. As the coil pulls heat from the surrounding air, condensate naturally collects in the pan below, and without a heat source at the base, that water freezes and blocks the drain outlet over time. Within HVAC systems, this heater keeps the tray surface above freezing so that liquid vapor continues to drain freely, making it a practical addition to evaporator sections in refrigerated display cases.
