Built for the poultry, meat and feed industries, the Nercon washdown spiral includes an edge-driven conveyor, an open-belt surface design, solid-UHMW guide rails and a self-draining, bent frame construction. The sprockets that drive the chain in multiple locations distribute the force across the entire length of the chain. The spiral withstands washdown pressures up to 1,500 psi and the moderate use of corrosive chemicals.
