Function:

• After approaching the appropriate inlet branch, the flexible special hose with the nozzle lance is passed through an adequate feed tube into the top of the boiler.
• The cleaning process begins as soon as the nozzle lance has passed through the boiler roof.
• Through the heavy nozzle lance, which is directed vertically downward, the high-performance nozzle delivers the water uniformly to all surfaces of the boiler area to be cleaned.
• Setting of the correct operating parameters ensures that major thermal loading of the tube walls is avoided.
• On reaching the lower end position the direction of movement changes and the nozzle tube returns to its starting position.

Special features:

• lineal drive guarantees exact positioning above the inlet branches (number and distance of inlet branches freely selectable)
• high-performance nozzle with variable drop spectrum
• heat and corrosion-resistant stainless steel hose
• hose advance drive - controlled advance speed for optimum and safe cleaning
• distance probe for precise measuring of cleaning speed and cleaning height
• hose reel with automatic winding unit
• inlet branch on the boiler roof 
• flue gas-proof gate valve 
• sealing air fan
