QUIET THUNDER® ELECTRIC VIBRATORS
About Quiet Thunder® Electric Vibrators
AC Models
Quiet Thunder® Electric Rotary Vibrators operate on alternating current (AC). They are especially useful where air or hydraulic power sources are not available. A major advantage of Electric vibrators is they are extremely quiet; the only noise is the hum of the electric motor. Global's QT and DEG Series electric vibrators are available in 2-pole (3600 RPM), 115, 230, & 460 voltages, 60 Hertz, and single or three-phase AC current.
Electric Rotary Vibrators produce vibration of low to medium frequency and a wide range of forces. The smallest Electric Vibrator generates 40 force pounds (.18 kN) of centrifugal force, while the largest generates 3,300 pounds of force (14.68 kN). The largest electric vibrator is capable of handling a load up to 33,000 pounds (14,969 kg). Use multiple vibrators on a single hopper when the load is greater than 33,000 pounds. For example, to restore flow to a hopper with 60,000 pounds (27,216 kg), use two of the largest Electric Vibrators. For more information please see:

Advantages of Quiet Thunder® Electric Vibrators:
- Rugged Construction - The housings of the DEG models are made of rugged ductile iron. The QT models have cast aluminum housings with 304 stainless steel covers.
- Shock Resistant Motor Windings - Vacuum system process applied to QT stators for protection.
- Extremely Quiet – Only hear the hum of the electric motor.
- Highly Efficient - Less expensive to operate than pneumatic vibrators.
- Adjustable Force Settings - Centrifugal force settings can be quickly and easily changed, without the need for special tools, to accommodate different loads.
- Long-lasting - DEG models use high capacity bearings, permanently sealed, allowing vibrator to handle tough applications without maintenance. QT models have a labyrinth type grease seal, which gives long lubrication life.
- Weather Tight Construction - To keep out contaminants, DEG models are sealed with silicone and QT models have o-ring seals.
- Produces Uniform, Directional Flow.
