It takes several components to produce automotive windscreen wash. But the combination of specific components from SPX can make the job much more efficient.
That was the case for a chemical manufacturer which installed two stand-alone automated blending plants, designed by SPX Process Equipment, to optimize processing efficiency at its plant in the United Kingdom.
The company previously created batches of its product manually, a time-consuming process, and then transferred the product to a storage tank or directly to a machine. The solution provided by SPX Process Equipment, speeds up and streamlines the process.
The SPX Multi-brand Solution
Each of the two automated blending plants supplied to the customer were equipped with a Bran+Luebbe® touch screen display and control panel for easy recipe selection and for specifying flow rate and batch size requirements. Each system was also fitted with a special pump in order to transfer externally stored alcohol from a bulk storage area to the main processing rig.
At the rig, water is pumped through a flow meter using a Johnson Pump® centrifugal unit. Depending on the specific product being produced, a concentrated pre-mix of surfactants, perfume and coloring dye may be introduced using a Bran+Luebbe metering pump.
Alcohol and water is then mixed in-line using a Bran+Luebbe static mixer. The mixture passes through a mass flow meter where its total flow rate and density can be measured.
The final operation brings the premix and water solution together through a static mixer. The process is closely monitored and uses proportional–integral–derivative (PID) control, which eliminates the need for continuous operator attention, to help ensure that the final product is always within specification.
