Did you know
- The Cummins Turbo Technologies (Holset) HE Series has seen various models introduced over time. For example, an upgraded HE600 Holset Turbocharger began production in 2020. The HE200WG is scheduled for an official product launch at the end of 2024. The 8th generation HE400VGT is also slated for a 2024 launch. The HE300VG replaced the HE351VE on 6.7L Cummins trucks from 2013-2024. Holset was acquired by Cummins Inc. in 1973 and rebranded as Cummins Turbo Technologies in 2006.
- The HE Series encompasses a range of turbochargers designed for various engine sizes and applications. The HE200WG supports light-duty diesel engines from 3.8 to 5.3 liters. The HE250 and HE300 Wastegate Turbochargers are suitable for 5.5-8 liter medium-duty diesel engines and 8-11 liter natural gas engines. The HE400VGT is intended for the 10- to 15-liter heavy-duty truck market. The HE600 series can overlap in flow range with the larger HE800 series, allowing for downsizing in some applications.
- The HE Series turbochargers are chosen for their enhanced efficiency, durability, and ability to meet stringent emissions regulations. They often feature advanced aerodynamic designs, improved compressor and turbine stages, and offer benefits like better fuel economy and transient response.
