DERC Dome Cleaner

The solution for safe cleaning in confined spaces

The DERC Dome Cleaner is an easy to use tool for high pressure cleaning of vertical heat exchangers with limited access. With the operator out of the line of fire and easy operation of all functions, this modular dome cleaner makes an easy-to-use and install tool for many applications.

The basis of the Dome Cleaner, the air motor with gear box, is installed in the middle of the heat exchanger and mounted to the tube sheet. The base is fixed by 3 pins which are expandable and will fit into the tube of the heat exchanger. Based on this, an aluminium rail rotates and holds the bracket with the flex lance guide and hose stopper. Positioning the lance guide by the operator is made easy by the optional two cameras/ display, installed on the tool. For feeding and retracting the high pressure flex lance, a hose feeder is connec¬ted by a flex guide snout to the flex lance guide.

• Safe jetting, the operator out of the line of fire
• Modular, easy to adapt and works with any hose feeder/ tractor
• Air powered
• Camera supported (optional)
       • 2 Air Knifes installed in front of camera’s to keep these clean
