Hi again,

Themis is a family of servo motor drives for agitation purposes from Cronus-PCS. 

The Cilix drive unit is unique as to the real-time info about delivered kinetic power (watt) and torque. This means that for agitation of 0.5 - 5 liter bioreactors or fermenters one can now get real-time, measured, calculated impeller or turbine Power Numbers (Np). 

The larger “sister” Perseus handles 5 - 50 liter SUBs and supply real time Power Numbers as well.

The digital Cilix driving two BLDC servo motors size either NEMA-17 and/or the smaller NEMA-13. Photos show both the size NEMA-17 and the smaller NEMA-13 servo motors mounted with ID30 adapter. Right photo show the NEMA-17 size driving a 0.5 liter CellVessel with 35 mm impeller and HPD drive from www.cercell.com with NP of 1.2.
