Full spec and performance data.

Description The self-regulating heating elements increase their heat output when pipe temperatures fall and decrease their heat output when pipe temperatures rise. The heaters will maintain pipe temperatures up to 250°F (120°C) and will withstand 150 psig saturated steam purging, 366°F (185°C). To help protect against impact and mechanical abuse, the heating element is available with either a 100% tinned copper or 100% stainless steel overshield. Factory Mutual approved for use in Class I, Division 2, Groups S, C, and D; Class II, Division 2, Group G; Class III, Division 2 areas. It is rated for 13 per NEC and meets or exceeds requirements of IEEE 515 Electrical Resistance Heat Tracing Specifications.   Applications Basic design – Ordinary use only.   Tinned copper overshield option – Mechanical protection in non-corrosive applications.   Stainless steel overshield option – Mechanical protection in mildly corrosive applications.   Tinned copper overshield with fluoropolymer jacket option – Protection where exposure to organic chemicals or corrosives is expected. Monitor wires option – Allows for continuous monitoring of both bus wires for continuity.
