The Model PCS-621B system is a skid mounted complete mixing and pumping unit. This unit is state-of-the-art in mixing and density automatic control. The 7 bbl mixing and 20 bbl averaging tank makes the operator’s job easier, provides a cushion for fluctuations in bulk delivery, and provides excellent density and additive concentration averaging.
