The project in context

Technology in its operating context.

Shutdown maintenance at a chemical plant in Pardubice combined work on fans, evaporators, pumps and associated pipework. The site diary records dismantling, repairs, resealing and reassembly; the work area was handed over on 3 July 2026.

Scope of work

Four fans and two evaporators in the service schedule
Pumps with cooling tanks and a Venturi scrubber
Separation station with screw, decomposition vat and pipework
Mechanical repairs, bearing replacement and joint resealing

Associated equipment within one shutdown

The invoiced schedule divides the work into thirteen service items. It includes RVI 800, RVI 630, RVI 400 and RSTr 500 fans, two evaporators, two pump-and-cooling-tank groups and a Venturi scrubber with a pump. It also covers a separation station with a screw, a decomposition vat, a sodium nitrate solution tank and pipework.

The scope combined rotating equipment, vessels and their piping connections. The service-item structure linked dismantling, repairs to individual parts and subsequent reassembly.

Recorded installation and repair work

Daily records describe removal of motors with gearboxes, inspection and repair of the screw including bearing replacement, and reconnection of piping. Reassembly included replacement of joint gaskets and resealing of valves.

Near the end of the shutdown, the diary records reinstallation of fan impellers and sealing of a fan casing cover. Following completion and cleaning, the work area was accepted without comments on 3 July 2026.

Outcome

Completed shutdown installation and repair work, with the work area accepted without comments.
