The TRUE 801805 drain line heater helps prevent freezing in refrigeration drain lines to maintain proper system operation. Rated at 10W and 115V, this component applies gentle, consistent heat along the drain line to keep condensation flowing and reduce the risk of blockages caused by ice buildup. It works by converting electrical energy into low-level heat that maintains temperatures above freezing in critical areas. This supports reliable drainage, minimizes maintenance issues, and helps protect surrounding components from damage. Its steady performance contributes to efficient operation and reduces downtime in commercial refrigeration equipment.
