Electrical freeze protection for long pipe- lines in both nonhazardous and hazardous locations

Description

The LHTR self-regulating heating cables provide freeze protection and low-temperature maintenance for long line applications. The LHTR heating cables maintain process temperatures up to 150°F (65°C) and can withstand intermittent exposure to temperatures up to 185°F (85°C).The cables are configured for use in non- hazardous and hazardous locations, including areas where corrosives may be present.The LHTR heating cables provide long circuit length capability. They can be used for continuous circuit lengths up to 1125 feet (342 m) powered from a single source.

LHTR cables are especially well suited for tracing long pipelines containing temperature sensitive fluids or where high reliability is required.
