Duct-O-Bar Heated Figure Eight Conductor Bar: Cold Storage, Outdoor, and Low-Temperature Crane Electrification 

Duct-O-Bar Heated Figure Eight is a specialized insulated conductor bar system engineered for overhead crane and hoist electrification in outdoor, cold storage, and low-temperature industrial environments where standard conductor bar systems are subject to ice formation, moisture ingress, and thermal contraction that degrade electrical contact reliability and compromise crane operational performance. The Heated Figure Eight system incorporates an integrated heating element within the conductor bar rail profile — maintaining the rail and contact surface at a controlled temperature that prevents ice and frost accumulation on the conductor surface, ensuring reliable collector engagement and uninterrupted crane operation in the freezing temperatures, high humidity, and condensation conditions encountered in cold environment US industrial applications. 

Heated Figure Eight is the specified conductor bar solution for US cold storage and refrigerated warehouse crane installations, outdoor crane runways in northern US states and Great Lakes industrial facilities subject to winter temperature extremes, food processing and beverage production facilities operating crane systems in refrigerated production areas, and outdoor material handling operations at port facilities, rail yards, and industrial storage sites where crane runways are exposed to precipitation, freeze-thaw cycles, and sub-zero operating temperatures during winter months. Ice and frost accumulation on the conductor surface is the primary cause of conductor bar failure and crane downtime in cold environment applications — and the Heated Figure Eight's integrated heating element eliminates it directly at the source.
