•Cleaning process can be validated using Alfa LavalRotacheckStandard designThe choice of nozzle diameters can optimize jet impact length and flow rate at the desired pressure.Alfa Laval offers a wide range of tank cleaning machines suitable for different duties and industries. An alternative that offers performance similar to the Alfa Laval SaniJet 20 is the Alfa Laval SaniJet 20 UltraPure for hygienic applications that require full traceability of product-contacted parts and smooth qualification and validation processes through the Alfa Laval Q-doc documentation package.Certificates2.2 material certificate, Q-doc and ATEX.Working principleThe high-impact jet stream from the rotary jet head covers the entire surface 360° of the tank interior in a successively denser pattern. This achieves a powerful mechanical impact with a low volume of water and cleaning media.The flow of the cleaning fluid makes the nozzles perform a geared rotation around the vertical and horizontal axes. In the first cycle, the nozzles lay out a course pattern on the tank surface. The subsequent cycles gradually make the pattern denser until at full cleaning pattern is reached.Once the full cleaning pattern is reached, the machine will start over again and continue to perform the next full cleaning pattern.TECHNICAL DATAAir motor:Must NOT be operated non-lubricatedMin. tank opening:3" clamp - rotacheck N/ACIP media recommended pressure: 5 - 8 barDry, dew point max.: 5 °C Must NOT be operated non-lubricated.
