Installation & Operation Recommended Mounting Location
Spray balls are typically located in the center of the vessel; however, this may vary per application. The depth to install the spray ball in the tank is dependent upon several factors. The primary considerations are the diameter of the tank and the depth of the head. The diagram above demonstrates the recommended installation for an upward spray pattern (model SB1). The installation of the spray ball at the proper depth ensures that the spray pattern is most effectively and evenly distributed for maximum coverage of the surfaces. Spray balls with 360° coverage (model SB5) may be installed as described above. However, other specially designed spray balls and models SB2 (two balls mounted to a tee assembly) and model SB4 (downward spray) may require other considerations. Please consult with Sani-Matic for recommended location. Preventing Spray Shadowing If there are components, such as shafts, agitators, or baffles inside a tank, the spray from a single spray ball may be blocked from contacting the surface (spray shadowing). The recommended solution is to install two static spray balls, so that the shadow effect is eliminated by the second spray ball – see Figures 2 – 4 below.
