As can be seen from the above list, QPEC has furnished numerous mixer settlers to a wide range of new and repeat clients. Our units are in use throughout the world, with numerous plants in Canada, Southeast Asia, the United States, and Chile, to name a few.
We have furnished units with settlers as large as 25' x 62' and 32' x 62' with mixers for Chevron's Pana Maria plant and Energy Fuels at Blanding, Utah. QPEC units have treated pHs in the 1.0 range, and gpm flows from 100 ml/min. to 2000 gpm.
We design our pilot plant units as package systems complete with all interstage piping and provision for recycles as necessary, mounted on a common structural steel frame, complete with electric drive motors in explosion-proof construction with VFD speed controls shipped separately for customer installation.
All of the companies shown on the above list purchased the complete mixer-settler units from Quinn Process Equipment Company. All systems started up quickly without complications or failures. They all performed to complete satisfaction without difficulty.
