Tefcold Evaporator Water Pan Heater

An evaporator water pan heater maintains the temperature of the condensate collection pan inside a refrigeration unit. During operation, moisture from the air condenses on the evaporator coils and drips into the pan. Without heat, this water freezes in low-temperature environments, blocking drainage and causing ice to accumulate on the coils. The heater warms the pan just enough to keep the water liquid, allowing it to drain away before it can freeze.

The heater is installed directly beneath or adjacent to the water pan, secured in place with mounting brackets or adhesive pads. It operates continuously while the refrigeration unit is running, drawing a small electrical load to sustain the necessary warmth. No manual intervention is required once fitted; the heater cycles automatically to prevent ice formation.

Constructed for refrigeration environments, the heater is sealed against moisture and designed to withstand the temperature fluctuations typical of evaporator pans. It connects to the unit's existing electrical supply, matching the voltage and wiring configuration of the refrigeration system it serves.

This component is a direct replacement for Tefcold evaporator water pan heaters in compatible refrigeration units. It fits models where the manufacturer specifies this article for defrost maintenance.
