Delco Remy has introduced several enhanced heavy-duty brushless type alternators for the commercial truck and transit bus market that is says are more durable and reliable.

According to the company, the redesigned 24SI and premium 32SI models are designed to optimize power output and service life for trucks equipped with high-temperature EPA-compliant engines.

Featuring Delco Remy's new Maximum Cooling Technology design, the alternators have dual internal fans and high-flow front and rear air vents. This configuration is said to deliver superior performance over a temperature range of -40°F to 221°F.

These alternators are available in two versions: 12 volts (145 amps at 6,000 rpm) and 24 volts (100 amps at 6,000 rpm).

For transit vehicles, Delco Remy offers the 50DN, which combines the benefits of vibration-resistant brushless construction with a new Long Life Stator (LLS) assembly. The LLS assembly has a one-piece insulator design whose rigid leads help eliminate electrical grounds and shorts. According to Delco Remy, this provides better performance and reliability.

The transit vehicle alternator reduces heat-related performance issues by incorporating increased-diameter copper leads and by removing lead insulation, resulting in greater surface contact with internal cooling oil, Delco Remy says. A new seal and collar assembly reduce friction-related wear while increasing the unit's pressure-handling capacity.
