AUS GENERATOR

Product catalog summary

Introduction
The document discusses the Daihatsu Diesel Aqueous Urea Solution (AUS) Generator, a device designed for the Selective Catalytic Reduction (SCR) NOx reduction system. This generator allows for the on-board production of high-grade AUS from urea powder and distillate water, eliminating the need for large storage tanks.

Specifications and Structure
The AUS Generator consists of a tank, pump, heating unit, and filters. It operates automatically to produce AUS with a fixed concentration, taking approximately 3 to 3.5 hours per cycle. The materials used include stainless steel for pipes, valves, and fittings.

Advantages

Space Efficiency: The generator reduces the need for large AUS storage tanks, requiring only a smaller buffer tank.
Cost Savings: Producing AUS from urea powder is more economical than purchasing pre-made AUS.
Quality Maintenance: Producing AUS on-demand ensures consistent quality, preventing degradation due to temperature fluctuations.
Ease of Loading: Urea powder is easier to load compared to liquid AUS, which requires additional equipment.

Model Selection and Usage
The document provides guidance on selecting the appropriate AUS generator model based on the average output of diesel generators and main propulsion engines in NOx Emission Control Areas (NOx-ECA). Models include DNS-300, DNS-500, and DNS-1000, each with different capacities and production intervals.

Cost Comparison
A cost comparison between urea powder and AUS is provided, highlighting the economic benefits of on-board AUS production.

Compliance and Standards
The AUS Generator helps ships comply with the IMO NOx Tier-III standards, which require significant NOx emission reductions in NOx-ECA.

Contact Information
The document includes contact details for Daihatsu Diesel offices worldwide, offering support and after-sales service.
