Iso-Fio® HD Voltage Block System Advanced voltage blocking technology for the electrostatic application of waterborne coatings. For many finishing operations, the most cost-effective way to reduce VOC emissions is to convert from solvent-based to waterborne coatings. But due to the higher electrical conductivity of waterborne coatings, it is necessary to isolate the charged paint-supply system from any ground source. These isolated systems are difficult to maintain and potentially dangerous The Nordson Iso-Flo HD voltage block offers an easier, safer and far more cost-effective way to spray electrostatically charged waterborne coatings. The system supplies charged coating to the spray devices while preventing the charge from conducting back through the paint-supply system. Nordson Iso-Flo systems are built for the most demanding finishing requirements with high-capacity, field-repairable pumps that provide long life with minimal maintenance and an innovative arc-suppression feature that allows continuous coating without delay between cycles. How the Iso-Flo HD System Works An Iso-Flo HD manual or automatic voltage block is installed near the spray booth, and is connected between the grounded paint-supply system and the spray devices. Coating is pumped from the paint-supply system to paint reservoirs inside the voltage blocks. Electrostatic isolation is maintained with a series of shuttle valves that alternately connect the reservoirs to the grounded paint supply and the spray devices. Standard Iso-Flo HD configurations are available for single-gun manual painting systems and single- and multiple-gun automatic painting systems.

Iso-Fio® HD Voltage Block System Iso-Fio System for Manual Spraying single paint reservoir. The reservoir fills from the grounded paint supply ofFbetween parts. When the reservoir immediately disconnects from the grounded paint supply and connects to the spray gun. The electrostatic charge is applied within the Iso-Flo HD unit, between the paint reservoir Throughout the filling and spraying cycles, an air gap is maintained within the system to prevent the electrostatic charge from conducting back through the paint-supply system. Due to the speed of the shuttle, the operation of the Iso-Flo unit...

Iso-Flo® HD Voltage Block System ■ No need for isolation fluids. The air gap maintained in the Iso-Flo HD system provides complete isolation between the charged paint and the grounded paint supply without extra valves, seals, pumps, and isolation lubricants. ■ High-capacity, field-repairable pumps. Pumps deliver excellent performance and optimal flow rates with virtually all paints. Features such as self-adjusting pistons provide a smooth flow rate and long service life. ■ Immediate arc suppression for safe, productive operation. The arc suppression method of the Iso-Flo HD voltage block systems...
