Viscous Speed Governors (VSG) Innovation - 1

Viscous Speed Governors (VSG) from Enidine Features and Benefits • Safely and quietly controls rotary motion • Provides consistent speed control through 360º of rotation, in both directions VSG leads the expansion of our core product offering • Handles linear motion via simple rack and pinion integration • Industry standard shaft and keyway mounting configurations The VSG’s simple, lightweight rugged construction provides reliable performance for numerous industrial appli- • Wide range of ambient operating conditions - indoor or outdoor, -40º F to +200º F (-40º C to +95º C) cations. The VSG controls rotation of shafts and hinged loads by using silicone-based viscous shearing technology. • Customer-specified performance over a wide An inner rotor is surrounded by silicone fluid within the starange of operating RPM tionary housing. As the shaft rotates, the inner rotor shears • Maintenance-free - no adjustments required the silicone fluid providing resistance and smooth motion. Fluid viscosity of each VSG is selected after considering variables such as the components size, weight, spring assist and desired Typical Shaft Installation cycle time. Exploded View Common Applications • Overhead and rolling steel fire doors, grilles, and shutters Rotor Keyed to Shaft • Conveying - braking of free conveyor rollers and ramps • Material Handling - hoist integration, free-fall load protection Outer Cover • Steering Control - resistance offers over-steering protection Silicone Fluid • Amusement Industry - limiting sway and range of motion • Industrial Safety - controlling shaft or hinged loads • Marine Applications - 100% high-tech, non metallic construction Typical VSG Application Lateral Motion Ideally suited for the Rolling Overhead and Fire Door Control In new and retrofit applications, a single VSG can be installed on rolling doors by simply mounting to the keyed door shaft per the original door manufacturer’s instructions. Unlike noisy ratcheting devices, the VSG requires no adjustments during installation or while in-service and can control the closing and opening speed of most large doors. Multiple governors can be used to handle over-sized doors. Currently in use by most major door manufacturers, the patented VSG meets industry standards outlined by Underwriters Labratory, Warnock Hersey and Factory Mutual. It has passed the 3-hour fire door burn test and conforms to numerous industry standards. 7 Centre Drive | Orchard Park, NY 14127 Phone: 716.662.1900 | F
