Electro Static Technology
09003 SGR.jpg
Any truly “green” process must achieve sustainability as well as energy efficiency. AEGIS SGR™ Bearing Protection Rings from Electro Static Technology make this possible by dramatically extending the lives of motors controlled by variable frequency drives (VFDs). While VFDs deliver impressive energy savings (up to 30% or more), they also induce harmful currents on the shafts of the motors they control. These currents often damage motor bearings, and lead to costly downtime and premature motor failures. Without an effective means of shaft grounding, the currents will discharge through the bearings, causing damage to the bearing race walls. Over time, this can lead to noise, vibration, and bearing failure, severely reducing the reliability of an entire system and wiping out any savings from using the VFD.

05578ALT1 (wLogo,Motor -- SGR FOR HVAC).jpg
The new AEGIS SGR™ Conductive MicroFiber™ Bearing Protection Ring from Electro Static Technology improves the reliability of HVAC/R systems by dramatically extending motor life. By protecting bearings from electrical damage for the life of the motor, the AEGIS SGR prevents bearing noise and costly motor repairs and downtime. It is ideal for OEM motor and fan manufacturers, repair shops, HVAC service contractors, and in-house maintenance departments and can be easily installed as part of a preventive maintenance program.
