DFS Fusion™ MCBS+


The DFS Fusion™ MCBS+ blends slurries or aqueous chemicals through our inline On-Demand™ blend technology or by weight and volume. All blending methods receive chemical from the customer-supplied chemical source, UPW, or on-board vessels.

Blends are prepared in either of the two 114L blend and dispense tanks, and each blend is verified through the blend specific on-board metrology set. The system maintains and supplies constant temperature and pressure control to the production area tools. Maglev pumps (one per tank) are used for the main chemical supply, and pneumatic pumps are used for blend recirculation and transfer from external vessels.
