SCR SYSTEM

Product catalog summary

Overview: The document outlines the features and benefits of the Daihatsu Selective Catalytic Reduction (SCR) System, designed to meet the International Maritime Organization (IMO) NOx Tier III standards effective from 2016. The system is engineered to reduce NOx emissions by 80% compared to Tier I standards.

Key Features:

NOx Removal Performance: Compliant with IMO NOx Tier III standards, ensuring emissions are maintained below standard values.
Compact Design: The SCR converter can be installed vertically or horizontally, featuring an integrated silencer and a unique nozzle for efficient urea aqueous spraying.
Low Running Costs: The system optimizes urea aqueous spraying through electronic control, with optional automatic adjustment based on NOx measurements.
High Vibration Resistance: Includes anti-vibration support and a robust catalyst for marine environments.
System Expandability: An oxidizing catalyst can be added to reduce CO and ammonia slip.

System Components: The system includes a converter with a built-in catalyst, urea aqueous spraying nozzle, controller and control panel, urea aqueous pump unit, exhaust ducts, bypass damper, dust blower, service hatch, temperature sensor, and differential pressure sensor.

Operational Data: The document provides an example of automatic operation, showing load percentages and corresponding urea spraying amounts and NOx concentrations before and after SCR treatment.

Additional Information: The document mentions the availability of a separate brochure for the Daihatsu After-Service Network and notes that information is subject to change.

Contact Information: Includes contact details for Daihatsu Diesel offices worldwide, including Japan, Taiwan, Europe, America, Asia Pacific, and Shanghai.
