Our KRYO SSC unit bearing motors are primarily used in commercial refrigeration evaporator fan applications, but can be used in many applications demanding high efficiency and dependability with output ratings between 5 – 38 watts.

50 years after launching the most efficient shaded pole motor of its time, Morrill Motors is now offering the most efficient electronically commutated ball bearing motor available. The KRYO SSC significantly outperforms both shaded pole and PSC technology. With efficiencies three times higher than shaded pole motors and 45% higher than PSC, in addition to the reliable and quiet unit bearing design, the KRYO SSC provides users the most reliable and best energy savings solution for their applications.
