Self-Regulating Heat Tracing Cables
Delta-Therm TT, CO, IN, and HT series self-regulating cables vary wattage output along their heated length in response to changes in ambient temperature. As ambient temperature decreases the cable will increase wattage output, and as ambient temperatures increase the cable will decrease wattage output.
The TT series cable is available for temporary pipe tracing installation and is typically installed in emergency disaster relief applications.
The CO series cable is a commercial grade pipe tracing cable typically installed for outdoor freeze protection applications.
The IN series cable is an industrial grade pipe tracing cable typically installed for temperature maintenance applications.
The HT series cable is a high temperature industrial grade pipe tracing cable typically installed for high temperature maintenance applications.
