Control system

Automatic high pressure mixer washout controller uses a small PLC for flawless operation
Control display shows status of inputs, outputs and allows setting of key parameters

Internal PLC gives the ultimate in functionality.  You can choose manual operation, timed mixer washout cycle or remote cleanout control from batching controller.  You can also use it as a concrete inter-batch wash.  Just time the water (because the pump delivers constant volume per minute, which is as good as metering) or meter it.  As a result, the water can be used in the subsequent batch.
