SLES Mixing and Dilution Unit 2021 | 1 SLES Mixing and Dilution Unit SLES* is an organic chemical compound with excellent cleansing and foaming properties. For this reason it is an ingredient of various detergents, household products, soaps and shampoos. SLES is usually supplied to the producers of above liquids at a concentration of 70%. Due to its physical properties, this concentrated solution is difficult to handle and must be diluted below 27% before using it in the process. rapid viscosity decrease 5% Solution concentration The innovative SLES Mixing and Dilution Unit designed by Tapflo enables an immediate and precise preparation of a less concentrated SLES solution. This device gives a full control over the process of dilution, providing SLES that is homogenous and stable over time. Water and extra additives SLES solution diluted below 27% 70% SLES solution Constant mixing Continous or batch supply of SLES solution at a given concentration Independence from deliveries of diluted SLES Immediate start of mixing process Flexibility and continuity of production Constant tracing and recording of operation parameters High quality of the on-site prepared SLES solution Small in size, lightweight and well thought-out construction Significant costs reduction of SLES purchase, transportation and storage Local or remote control over the Unit Additional savings on the warehouse space Possible extensions: • dosing of additional ingredients • feeding 70% SLES solution directly from a road tanker Simple and user-friendly control system *SLES - sodium laureth sulfate
