MH&W International Corporation presents CoolTUBE® Radiated Emissions Absorber for the highest reliability and longevity of your VFD motor system!
Variable Frequency Drives (VFD) create Electromagnetic Interference (EMI), conducted and radiated, in VFD motor systems. Without the use of some type of filter or choke system, related failures will occur. Unique to the industry, CoolTUBE® absorbs this high frequency noise before it gets to the motor system and causes damage. By acting as a common mode choke and absorbing the damaging high frequency noise (frequencies from approximately 5MHZ-1GHz), you can maximize equipment reliability, reduce maintenance costs, and avoid unscheduled downtime. CoolTUBE® mitigates radiated EMI issues in all VFD motors including servo and DC motors.
CoolTUBE® Nanocrystalline absorbers are superior to other soft magnetic materials like ferrites because of significant advantages concerning their magnetic properties. Therefore, only about 20% of ‘magnetic mass’ is required.
