Remy Inc., manufacturer and marketer of Delco Remy heavy-duty electrical systems, says its new family of heavy-duty alternators is designed to ensure adequate alternator output in spite of increased underhood operating temperatures.

The company says the high-temperature alternators – the Delco Remy 28SI, 36SI and 40SI – are engineered and tested to ensure unsurpassed output in underhood operating environments up to 257 degrees Fahrenheit. According to Delco Remy:

  • The 28SI heavy-duty brush-type alternator delivers up to 180 amps of power at highway speed and 130 amps at idle. The design features a dual-internal-fan technology that helps ensure optimal cooling efficiency within tightly packaged heavy-duty engine compartments;
  • The 36SI premium brushless alternator produces 160 amps at highway speed and 110 amps at idle; and
  • The 40SI is engineered to deliver 300 amps at road speed and more than 200 amps at idle.
  • All three alternators feature a variety of technologies – including a “Flex-Lead” diode-bridge design and higher-capacity, press-fit diodes – suited to applications with higher underhood temperatures and increased vibration, the company says. Each also is available with Delco Remy’s Remote Sense technology, designed to adjust output automatically based on voltage at the battery terminals to help ensure the optimal state of charge.
