  • Page 5: Purpose

    1 Purpose The purpose of this document is to give sufficient information on how to install and operate the key components of the SCRmarine system. The installation guideline also describes the post adjustments and inspection processes and gives general information on service and maintenance.

  • Page 6: System Overview

    2019-05-15 Issue: 1.8 Installation Guideline 1.2 System overview The schematic diagram in Figure 1 shows the layout of the SCRmarine system. It is a fully automated after-treatment NOx reduction system with simple calibration and low maintenance requirements. Figure 1. SCR marine system, arrangement and layout 1.

  • Page 7: Components Overview

    2019-05-15 Issue: 1.8 Installation Guideline 1.3 Components overview The following are the key components of the SCRmarine system. Some parts are optional, such as the POC (Particle Oxidation Catalyst). Appearance and contents can vary between specific systems. DEF Service Tank...

  • Page 8: System Requirements

    Installation Guideline 1.4 System requirements The SCRmarine is an automatic NOx reduction system. It is based upon a NOx sensor measuring the actual emissions from the engine and therefore requires little or no calibration during commissioning. An SCR catalyst assembly, and optionally a POC (Particulate Oxidation Catalyst), is installed in the exhaust line as close to the engine as possible to preserve exhaust temperature.

  • Page 9: Exhaust Components Installation

    The canning of the exhaust components is produced of stainless steel with flanges on the in- and outlet ports. The shape of the flanges can differ due to regulations and/or customer demands. Please observe the type of flanges in the BOM for your SCRmarine installation kit.

  • Page 10: Thermal Expansion

    It is important to leave space for the insulation at the installation. In a typical installation the insulation is minimum 50 mm thick. Additional insulation may be required according to regulations and/or customer demands. STT Emtec AB (pbl) Tel: +46 (0)60-64 10 40 Head office: Njurunda Box 46, Njurundavägen 16A...

  • Page 12: Poc (Particle Oxidation Catalyst)

    Insulation. Additional brackets to support the POC assembly may be needed depending on the surroundings and support of other parts. STT Emtec recommends the use of metal resilient elements type Vibratec® or similar. Additional insulation may be used according to regulations and/or customer demands.

  • Page 13: Def Dosing Components Installation

    Installation Guideline 3 DEF dosing components installation This section provides information on installing and maintaining the DEF dosing components of the SCRmarine. 3.1 General The dosing components are designed to carry liquid DEF from the service tank to the exhaust stream. When dehydrated the DEF solution will form salt deposits from its Urea content.
