Description
Applications
• Nelson Type SLT heating cable provides a solution for ice dams that can build up and damage building roofs, gutters, and downspouts.
• During winter months, snow and ice accumulation on roofs can prevent proper drainage of water when regular melting occurs. Water stands on the roof and can be refrozen during cold nights resulting in expansion and potential roof damage.
• Nelson’s SLT ice melting heaters are designed for installation on roofs and gutters to melt a pathway for the drainage of water. The heating cable’s self-regulating feature provides additional benefits as well.
Features
• Nelson SLT heating cable is a parallel circuit, self- regulating electric heater.
• An irradiated cross-linked conductive polymer core is extruded over two multi-stranded, tin-plated, 16-gauge copper bus wires. The conductive core material increases or decreases its heat output in response to temperature changes.
• A waterproof thermoplastic elastomer over jacket is then extruded over the inner jacket for dielectric protection and
additional moisture resistance.
• A tinned copper braid is installed over the second jacket providing a continuous ground path.
• A flame retardant, UV stabilized polyolefin over the jacket, is then extruded over the braid.
• Lower Energy Consumption
– The heater automatically reduces its power output as drainage tunnels are formed in the ice and snow.
• High-Temperature Protection
– Because the heater self regulates its power output as a function of temperature, it cannot overheat and melt or damage temperature-sensitive roof coatings.
