General-purpose silicone rubber heating tape has a built-in thermostat control called T-Tape, which allows maintenance workers to stock heating tapes that are ready to plug in without the need for additional temperature control. The built-in thermostat controls the tape at approximately 60oF. The grounded tape is suitable for viscosity control or freeze protection and is available in several lengths.
