UBD A rotary heads are a simple but very efficient device for cleaning tanks inside. The rotary disk is rotated by the cleaning fluid and produces a very dense spray that reaches all parts of the inside surface. It is the only mobile part of the unit and requires no servicing at all. No lubrication is required, and therefore, there is no risk of contaminating your product with oil or grease. The device does not easily clog tanks to a minimum internal passage of 2 mm dia and will continue to operate even when feed holes are partially closed. Ideally suited for aggressive environments, it operates efficiently with all detergents and chemical solutions in both closed and open tanks because it is available with 360 or 180-degree spray patterns. UBD A models find their application in the pharmaceutical, food and chemical industries.
