- Hydrodynamic cleaning technology:
| In this operation, high-pressure (p = 35 MPa) water is sprayed onto inner space between
packs of exchanger sheet baskets.
Water streams with high kinetic energy with Q=500 l/min flow letely and original

| For this purpose, bearing beams with driving cars
where nozzle sets are mounted are installed radially, inside the flue pipe on both sides of the rotor (from
the top and bottom). In cleaning, the exchanger drive is controlled with an inverter whose task is to maintain
the rotor's required rotational speed ensuring that solidities will be completely |

The duct sets are driven with a high-pressure plunger pump with a diesel engine installed
in a soundproof container on the undercarriage of Mercedes Actros.

- Benefits:
- the highest surface cleaning class compared with other cleaning methods,
- no work-consuming dismounting and re-installation of heating baskets is required (we avoid a situation when
packs are destroyed during installation and dismounting),
- no adverse environmental impact by eliminating moistening (corrosion) and secondary cleaning of buildings
and boiler-house equipment (silting),
- no large overhaul areas for cleaning must be arranged
- short execution time (LUVO up to 24 h ; REGAVO 48 to 56 h)
- high availability and mobility allowing for quick response.
