Hunter Spring has been manufacturing static grounding reels, also called static discharge reels, for more than five decades. The company’s reels are used throughout the world for grounding and bonding military, commercial, and industrial equipment.
Hunter Spring supplies to many customers in the aircraft refueling and fuel transportation industries and meets rigorous specifications (A-A-50696) in crucial applications where static electricity discharge can lead to a spark and cause subsequent explosion.
The ROTA-REEL and Heavy-Duty ML-3416 and ML-2930 series reels available from Hunter Spring offer reliable performance and can be utilized when combustible materials are transported between carriers (truck to tank, rail to truck, rail to rail, etc.). These static grounding reels are perfect for use in ground support for refineries, terminals¸ aircraft, and bulk powder transfer stations. The newly designed stainless steel reels from Hunter Spring provide improved protection in adverse, combustible dust, and outdoor environments. They can also be used in food and pharmaceutical applications where paint and surface coatings are forbidden.
All heavy-duty ML-3416 and ML-2930 models from Hunter Spring are integrated with an internal retraction brake that slows down the cable’s retraction speed between 2 and 7 ft/second.
