The CTV-1500 cooling tower vacuum with filter is designed to remove slime, algae, mold, and other contaminants from the sides and floor of any cooling tower basin or sump without the need to drain the system. The company's CTV-F2 filtration system is specifically designed to work with the CTV-1500 and together, the unit can handle the high flow and small micron filtration requirements encountered in cooling towers, according to the manufacturer.
