All inspections

Overall exterior view of CleanSwitch RTO unit with ductwork, access platform, ladder, and adjacent control enclosure all intact; no abnormalities described.

Overall exterior view of the CleanSwitch RTO unit shows the equipment intact with ductwork, access platform, ladder, and control enclosure all in place with no visible abnormalities.

Manifold interior shows a uniform layer of process buildup/deposits coating the walls and the switch valve face, consistent with the most common defect in this fleet.

Manifold interior shows a uniform layer of process buildup coating the walls and the switch valve face/seal plate area.

Interior view of switch valve showing inlet baffle, valve face, and main seal ring area with surfaces appearing clean and undamaged.

Overall exterior view of CleanSwitch RTO unit documented during routine PM inspection; unit appears intact with ductwork, access platform, ladder, and control enclosure all in place and no visible abnormalities.

Manifold interior shows a uniform layer of process buildup coating the walls and the switch valve face/seal plate.

Manifold interior shows uniform light-grey deposits coating the walls and the switch valve face, consistent with process buildup.

Overall exterior view of CleanSwitch RTO unit with ductwork, access platform/ladder, gas piping, and control enclosure all visible and intact; no abnormalities observed.

Overall exterior view of CleanSwitch RTO unit with ductwork, access platform, ladder, and control enclosure all visible and intact; no abnormalities observed.

Process buildup visible on valve driven gear tooth flanks and surrounding area; drive plate mount and gear mesh otherwise appear intact.

Image is a reference schematic showing valve gap measurement positions A1–A26 on the circular manifold cross-section, not an actual inspection photograph.

Image is a reference schematic showing B-side valve position layout (B1–B26) used for documenting gap measurements; no equipment condition is depicted.

Drive gear and driven gear mesh are visible with light process buildup/residue around the gear teeth and surrounding valve body area. No zero-gap conditions or significant damage observed; buildup appears typical and does not obstruct the assembly.

Overall exterior view of Dürr CleanSwitch RTO unit documented during routine PM inspection. Unit appears intact with ladder, platform, ductwork, and control enclosure in place; no visible abnormalities.

Overall exterior view of CleanSwitch RTO unit showing ductwork, access platform with ladder, control enclosure, and gas piping; no abnormalities visible.

Overall exterior view of Dürr CleanSwitch RTO documented during PM inspection following last month's lightning strike; unit appears structurally intact with no visible damage, corrosion, or panel deformation from this vantage.

Overall exterior view of CleanSwitch RTO unit with ductwork, access platform, ladder, control enclosure, and gas piping visible; no obvious lightning-related damage, corrosion, or structural issues apparent from this angle, though technician should verify electrical/grounding connections in detail given recent lightning strike history.

Overall exterior view of Dürr CleanSwitch RTO unit documented during routine PM inspection. Unit appears intact with no visible abnormalities.

Overall exterior view of CleanSwitch RTO unit with ductwork, access platform, ladder, and control enclosure visible; no abnormalities observed.

Drive gear and driven gear mesh visible with light buildup/residue on gear teeth flanks; no obstruction of valve body measurement points evident in this view.

Severe process buildup observed on the upper valve body and accumulating between the driven gear teeth, consistent with technician's first-hand observation. Buildup is heavy enough to potentially obstruct gap measurement and degrade gear mesh.

Inspection of the RL Rotary Valve drive gear mesh area shows visible buildup/residue on the gear teeth and surrounding valve body, consistent with typical process accumulation. No obvious mechanical damage to the gear flanks or drive plate is evident.

Image is a reference schematic showing the B-side valve position layout (B1–B26) used for documenting gap measurements; no equipment condition is depicted.
