Select a model to see where it fits in the family. Every class shares the same filtration, controls, and enclosure — only the flow rate changes.
C9
Mini-MasterThe C9 Mini-Master centralizes an entire small fuel plant — 1 to 4 generator systems — on one compact touch-screen panel. It runs any of the five programmable functions with full Modbus/BACnet connectivity, in the same wall-mount footprint as a single-function control.
Power
120-230 VAC, 1 Phase, 50-60 HZ

C900
Master (Centraplex)The C900 Master Centraplex scales master control to 3–20 generator systems for the largest sites — hospitals and data centers. Same five functions, same touch-screen interface and Modbus/BACnet connectivity as the C9, in a full 36×24×8 in central panel built to coordinate an entire campus fuel plant.
