    Systems compose

     

    Brush (One (1) per tube set):  Each brush to be nylon bristle, titanium wire and polypropylene tips. 

    Basket (Two (2) per tube set):  Low pressure drop design, polypropylene basket with removable 4-prong end-clip;

    Four-Way Valve:  Reversing the condenser water flow for about 30 seconds every 6 hours

    Pneumatic Actuator:  Operating with 4 Bar to 7 bar air pressure supplied by customer.

    Control Panel:  Siemens S7200 PLC module to permit reversing the direction of water flow

           

    How it Works

    The four-way valve automatically reverses water flow in the condenser for about thirty seconds, once every six hours. The valve fits into the condenser supply and returns piping and is custom manufactured to suit any piping configuration.

    Nylon-bristled brushes are propelled through the tubes with the reversed water flow. Working in conjunction with good chemical treatment, the brushes clean the tube walls to eliminate scale formation and fouling. Each brush is designed to have a 0.025-inch interference fit in the tube wall.

    Open-ended low-pressure drop catch baskets are installed in the tube ends at the tube sheet to capture the brushes in the condenser heads. Removable end-clips allow for eddy-current testing and brush replacement, which is normally recommended every four to five years.

    ATB System Benefits

    Energy Savings - Lower fouling factors provide more efficient heat transfer. Electrical energy consumption is reduced by 10 to 30 percent when average fouling is eliminated. The ATB System is guaranteed to provide a 0.0001 fouling factor or better.

    Maintenance Savings - Because the ATB System cleans condenser tubes each day, the need to manually clean tubes is eliminated. Labor and material costs for maintenance are greatly reduced.

    Reduction of Downtime - The ATB System eliminates the need to shut down heat transfer equipment throughout the year. In process industries unscheduled downtime to manually clean tubes costs even more than the energy loss created by tube fouling.

    Reduction of Chemicals - Because the ATB System keeps precipitates from forming on tube walls, periodic acid cleaning is eliminated and normal chemical treatment can often be reduced.
