ESW LongviewESW Longview

The Longview® is specifically designed to provide cost-effective diesel particulate (PM) and NOx reductions for in-use diesel engines operating in on-road applications.

Configured in a modular, user-friendly design, Longview integrates a NOx reduction catalyst and a catalyzed wall-flow silicon carbide diesel particulate filter. This provides simultaneous reduction of NOx, PM, hydrocarbons (HC) and carbon monoxide (CO) from one system. Features of the Longview include:

  • CARB verification to Level 3+ (>85%) for PM
  • NOx reduction of at least 25%
  • Proven retrofit solution with over 3,000 in operation
  • Uses diesel fuel rather than ammonia or urea as a NOx reduction agent
  • Reductions claimable for SIP and Transportation Conformity
  • Eligible for local, state and federal funding programs

The Longview is managed by ESW CleanTech’s proprietary MLC® which monitors system parameters and controls NOx reductant injection. The MLC also logs the monitored parameters for later retrieval and analysis.

ESW CleanTech uses only the highest quality materials, including all stainless steel construction, and a robust silicon carbide diesel particulate filter for enhanced durability. Additionally, numerous inlet/outlet end cone configurations are available for installation ease.

The modular design of the Longview facilitates service and de-ashing of the diesel particulate filter. The reusable metal seal (i.e. no gaskets to replace!) and band clamp design enables quick turnaround for maximum uptime.

The Longview balances the mandate for cleaner air with the demanding requirements of real-world on-road diesel applications, and the desire to maximize the economic life cycle of your equipment, while avoiding costly replacement.
