Cold Start Thermal Unit Air Source

TVS | Superchargers

Eaton’s electrically-driven, TVS V180-based blower is part of a fully-optimized exhaust thermal management system developed in partnership with Tenneco to help engine manufacturers meet future emissions regulations.

The cold start thermal unit air source allows airflow to be efficiently and precisely controlled to maintain optimal aftertreatment temperatures.

The integrated exhaust thermal management system is anticipated to be ready for the start of production in 2025 to support regulatory timing.
