Iso-Fio® HD Voltage Block System

nnnn

Advanced voltage blocking technology for the

nnnn

electrostatic application of waterborne coatings.

nnnn

For many finishing operations, the most cost-effective way

nnnn

to reduce VOC emissions is to convert from solvent-based to

nnnn

waterborne coatings. But due to the higher electrical conductivity

nnnn

of waterborne coatings, it is necessary to isolate the charged

nnnn

paint-supply system from any ground source. These isolated

nnnn

systems are difficult to maintain and potentially dangerous

nnnn

to plant personnel.

nnnn

The Nordson Iso-Flo HD voltage block offers an easier, safer

nnnn

and far more cost-effective way to spray electrostatically charged

nnnn

waterborne coatings. The system supplies charged coating to the

nnnn

spray devices while preventing the charge from conducting back

nnnn

through the paint-supply system.

nnnn

Nordson Iso-Flo systems are built for the most demanding

nnnn

finishing requirements with high-capacity, field-repairable

nnnn

pumps that provide long life with minimal maintenance

nnnn

and an innovative arc-suppression feature that allows continuous

nnnn

coating without delay between cycles.

nnnn

How the Iso-Flo HD System Works

nnnn

An Iso-Flo HD manual or automatic voltage block is installed

nnnn

near the spray booth, and is connected between the grounded

nnnn

paint-supply system and the spray devices. Coating is pumped

nnnn

from the paint-supply system to paint reservoirs inside the voltage

nnnn

blocks. Electrostatic isolation is maintained with a series of shuttle

nnnn

valves that alternately connect the reservoirs to the grounded

nnnn

paint supply and the spray devices. Standard Iso-Flo HD

nnnn

configurations are available for single-gun manual painting

nnnn

systems and single- and multiple-gun automatic painting systems.
