ABB AW601715 Overview

ABB identifies AW601715 as the Secondary debubbler assembly in the Navigator 600 Silica multi-stream spare-parts documentation. The same documentation separately identifies AW601720 as the pre-heater assembly and AW601181 as the reaction coil, manifold and cover. :contentReference[oaicite:2]{index=2}

This distinction is important because the secondary debubbler is a dedicated part of the sample-conditioning and optical measurement path. It should not be confused with the primary debubbler or the pre-heater assembly.

Navigator 600 Silica Application

The ABB Navigator 600 Silica is a continuous silica analyzer that uses controlled sample handling, chemical reactions and optical measurement to determine silica concentration.

The sample passes through the analyzer’s sample-conditioning components before entering the reaction section. After the chemical reaction, the sample flows into the secondary debubbler assembly before reaching the measurement cuvette. :contentReference[oaicite:3]{index=3}

AW601715 therefore occupies an important position between the reaction process and the optical measurement section.

Secondary Debubbler Function

The secondary debubbler removes air bubbles that may remain in the sample after the reaction process. ABB documentation explains that bubbles can originate from reagents or from additional degassing of the sample. :contentReference[oaicite:4]{index=4}

Removing these bubbles is important because air bubbles passing through the optical measurement area can influence the stability of the measurement.

The secondary debubbler therefore contributes to maintaining a consistent liquid sample condition before optical analysis.

Position in the Sample Flow Path

The Navigator 600 Silica multi-stream flow sequence places the secondary debubbler after the heated reaction coil and before the cuvette. The reacted sample enters the secondary debubbler assembly after passing through the reaction section. :contentReference[oaicite:5]{index=5}

The simplified process sequence can be represented as:

Sample Selection → Pre-Heater → Primary Debubbler → Reaction Coil → Secondary Debubbler → Cuvette → Drain

This arrangement allows the secondary debubbler to condition the reacted sample immediately before optical measurement.

Bubble Removal

Air bubbles can affect reagent mixing and optical measurement. The Navigator 600 Silica system therefore uses multiple debubbling stages.

The primary debubbler removes bubbles generated during the sample pre-heating stage, while the secondary debubbler handles bubbles that may remain or develop later in the process. :contentReference[oaicite:6]{index=6}

AW601715 is specifically associated with this secondary debubbling function in the multi-stream analyzer.

Cuvette Measurement

The secondary debubbler is closely associated with the analyzer’s measurement cuvette. The reacted and degassed sample is directed toward the cuvette for optical measurement.

ABB documentation describes a further function of the secondary debubbler assembly: during the optical measurement phase, sample flow can be diverted away from the cuvette through the associated valve arrangement. :contentReference[oaicite:7]{index=7}

This allows the solution in the cuvette to remain stable during the measurement period.

Optical Measurement Support

The Navigator 600 Silica measures the absorbance of the reacted silica complex through its optical system. Stable sample conditions inside the cuvette are therefore important to the measurement process.

The secondary debubbler supports this process by removing unwanted air bubbles and controlling the flow immediately upstream of the cuvette.

AW601715 should consequently be considered part of the analyzer’s combined wet-section and optical measurement preparation system.

Multi-Stream Configuration

ABB’s Navigator 600 Silica multi-stream documentation directly lists AW601715 as the Secondary debubbler assembly. :contentReference[oaicite:8]{index=8}

The multi-stream analyzer can accommodate multiple sample streams depending on its configuration. The selected sample passes through the common analyzer fluid-handling and measurement path before reaching the optical system.

AW601715 is part of this common secondary debubbling and cuvette flow arrangement.

Relationship to the Primary Debubbler

The Navigator 600 Silica uses a primary debubbler earlier in the sample path. ABB identifies the primary debubbler separately as AW600025. :contentReference[oaicite:9]{index=9}

AW601715 and AW600025 therefore perform related but separate functions.

Relationship to the Pre-Heater

ABB lists AW601720 separately as the Pre-heater assembly. The pre-heater raises the sample temperature before the primary debubbling stage, while AW601715 is located after the reaction coil. :contentReference[oaicite:10]{index=10}

These two components therefore have different positions and functions within the analyzer’s fluid path.

Relationship to the Reaction Coil

AW601181 is identified by ABB as the Reaction coil, manifold & cover. The reaction coil is positioned before the secondary debubbler in the sample flow path. :contentReference[oaicite:11]{index=11}

The reaction coil provides the controlled path for the chemical reaction, while AW601715 handles the subsequent bubble-removal and sample-flow functions.

Technical Specification Summary

Sample Flow and Degassing

The Navigator 600 Silica sample-handling system is designed to minimize the influence of dissolved and entrained air on the measurement process. The sample is first heated, which encourages dissolved air to form bubbles. These bubbles are removed by the primary debubbler. :contentReference[oaicite:12]{index=12}

After the sample reacts with the required reagents, it reaches the secondary debubbler. The secondary stage addresses bubbles that may originate from the reagents or further degassing of the sample. :contentReference[oaicite:13]{index=13}

This two-stage approach helps maintain suitable sample conditions for the optical measurement.

Measurement Stability

Air bubbles in the measurement path can cause unstable or noisy readings. ABB’s Navigator 600 Silica troubleshooting documentation includes checking the system for visible air bubbles when investigating noisy or unstable readings. :contentReference[oaicite:14]{index=14}

Because AW601715 is part of the secondary debubbling system, its condition can be relevant when troubleshooting problems associated with bubbles in the post-reaction sample path.

Maintenance Considerations

When inspecting the secondary debubbler assembly, attention can be given to the associated tubing, fluid connections, valve operation and sample flow.

A restriction or abnormal flow condition in the secondary debubbling section can influence the sample reaching the measurement cuvette.

The applicable ABB service documentation should be followed when disassembling, inspecting or replacing the assembly.

Compatibility Verification

Before selecting ABB AW601715, the following information should be verified:

• ABB part number AW601715
• Navigator 600 Silica analyzer model
• Multi-stream configuration
• Secondary debubbler arrangement
• Cuvette and valve configuration
• Associated tubing connections
• Wet-section configuration
• Applicable ABB service documentation

AW601715 is specifically documented as a secondary debubbler assembly for the Navigator 600 Silica multi-stream configuration, so the installed analyzer configuration should be checked before selecting the component. :contentReference[oaicite:15]{index=15}

Inventory Identification

For industrial inventory records, the recommended product description is ABB AW601715 Secondary Debubbler Assembly.

Additional searchable descriptions can include ABB AW601715 Navigator 600 Silica Secondary Debubbler, ABB AW601715 Cuvette Debubbler Assembly and ABB AW601715 Wet Section Debubbler.

The complete ABB part number AW601715 should remain the primary inventory identifier.

Service Replacement

When replacing AW601715, the existing tubing and connection arrangement should be identified before removal. The replacement assembly should be installed using the correct fluid connections and orientation.

After installation, the associated sample flow should be checked and the analyzer should be returned to normal operation according to the applicable maintenance procedure.

If the analyzer continues to show unstable readings after maintenance, the complete fluid path and optical measurement system should be evaluated rather than attributing the problem to the secondary debubbler alone.

Secondary Debubbler and Cuvette

The secondary debubbler is particularly important because it is positioned immediately upstream of the cuvette measurement stage. ABB describes the assembly as performing both bubble removal and sample diversion during optical measurement. :contentReference[oaicite:16]{index=16}

During the measurement phase, the sample flow into the cuvette is stopped before the optical reading so that the solution can settle. This supports a stable absorbance measurement.

Product Documentation

ABB’s Navigator 600 Silica multi-stream documentation lists AW601715 – Secondary debubbler assembly in Appendix H, Spare Parts. :contentReference[oaicite:17]{index=17}

The documentation also distinguishes AW601715 from AW601720, which is identified as the pre-heater assembly, and AW601181, which is identified as the reaction coil, manifold and cover. :contentReference[oaicite:18]{index=18}

This confirms AW601715 as a dedicated component within the Navigator 600 Silica multi-stream wet section.
