LONGVIEW®
The Cleaire 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 catalyzed wall-flow silicon carbide diesel particulate filter. This provides simultaneous reduction of NOx, PM, hydrocarbon (HC) and carbon monoxide (CO) from one system.
- CARB verified to Level 3+ (>85%) compliance for PM
- NOx reduction of at least 25%
- Eligible for local, state and federal funding programs
- The practical alternative to vehicle replacement
- Proven retrofit solution with over 3,000 in operation
- Reductions claimable for SIP or Transportation Conformity
- Uses diesel fuel rather than ammonia or urea as a NOx reduction reagent
- Durable state-of-the-art technology
Longview is managed by Cleaire’s proprietary MLC® which monitors system parameters and controls NOx reductant injection. The MLC also logs the monitored parameters for later retrieval and analysis.
Cleaire 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.
Longview’s modular design facilitates service and de-ashing of the diesel particulate filter. The reusable metal seal and band clamp design provides quick turn around for maximum up time.
The Cleaire Longview balances the need for cleaner air with the demanding requirements of real-world off-road diesel applications and the need to maximize the economic life cycle of your vehicles while avoiding costly replacement.
