I haven't looked lately but the last time I looked there were no such listed products. Greg - was the Chromalox listed for BL's? As a side note, it still says SMALL UNHEATED AREAS can use antifreeze or heat tracing. I would say heat trace is intended to be used only for portions of a systems but considering there are antifreeze systems in freezers that are 1,000+ gallon systems, I guess small is relative.
