Warmup NAMSR cable is suited to prevent liquids in metal and plastic pipes and ducts to freeze and clog up. It is regularly used in large residential and commercial construction for sprinkler lines, sewer pipes and A/C drains. Warmup cables are approved for dry and wet locations and suitable in the classes listed below. NAMSR Cable is constructed of a self-regulating polymer core that varies its output along its entire length, saving energy and eliminating hot spots along the pipe. Parallel construction makes it easier to install than series types of cable since it can be cut to length at any point on the pipe. It can be overlapped without overheating the cable.
