BAC Tech Tip

Basin heaters are normally selected to maintain 40°F pan water temperatures at 0°F ambient conditions. Your Local BAC Representative can offer selections for other conditions. Heaters should be interlocked with the system spray pumps so that the heaters are not running when there is a heat load, and are energized when there is no heat load and the basin water temperature is 40°F or less.
