Thermwire Compressor Heaters provide safe reliable freeze protection of residential HVAC compressors. Preassembled units include factory terminated cold lead with plug or flying leads, end seal and integral zip tie for fast reliable installation. Models available for 120 and 240 volt use. These cables are designed to heat the bell of the compressor to prevent oil and refrigerant separation at cold temperatures thus preventing premature compressor wear.
