High Speed Dispersers from Ross feature a National Electrical Manufacturers Association (NEMA) 7&9 Operator Panel and grounding systems.

High Speed Dispersers from Ross feature a National Electrical Manufacturers Association (NEMA) 7&9 Operator Panel and grounding systems. The dispersers can be used in hazardous environments where flammable vapors, liquids, solids, and/or dusts are present. The saw-tooth blade of the High Speed Disperser turns at tip speeds up to approximately 5000 ft/min and creates flow in low to medium viscosity formulations under 50,000 centipoise. The dispersers’ grounding systems are designed to ensure that the vessel is properly grounded before the agitator is allowed to operate. 
The dispersers’ control panel features start, stop, and emergency stop pushbuttons; a speed potentiometer; digital readout for agitator speed; and a 16-ft. grounding clamp device. Also supplied on the mixer are explosion-proof limit switches for locking out the motor if the blade is in a raised position or a mix vessel is not in place. The dispersers are available in sizes from 1 to 500 HP for batches from a gallon to more than 5000 gallons.
