Coating Delivery Systems
Insight Process Solutions specializes in fluid delivery systems for Precision
Coating systems, such as the Slot, Curtain, or Slide Coating methods. Our
experience designing innovative flow control, in-line mixing, and degassing
systems comes from the precision photographic coating industry. The solutions
described on this page, however, can provide cost-effective quality
improvements to any coating operation.
High Rangeability Metering Valve (Patent Pending)Insight's new High Rangeability Metering Valve is a high performance solution for your critical coating delivery applications. This valve is capable of 10,000:1 flow rate range in the same valve, with easy control of low flow rates down to 0.1 ml/min and below. The valve has a hygenic design, holds absolutely no bubbles, and is fully compatible with the most unstable shear sensitive solutions, emulsions, and dispersions. Valve comes with customized control algorithms necessary for proper operation. Available in a variety of materials and tubing sizes.
Pumpless Delivery Systems
Insight Process Solutions has developed an innovative "pumpless"
delivery system. This system throttles coating fluid from a constant pressure
vessel to the coating head using a special Low Shear Metering Valve and enhanced
control algorithms. Simple, low-cost transfer pumps are used to filter the fluid
and pressurize the holding vessel. Flow meters are used to assure precise flow
Advantages of Pumpless Delivery
Equilibar® Precision Back Pressure Regulator
Maintaining quiet conditions in the pressurized delivery vessel is crucial for high coating quality. To assure stability during upstream filter and batch swings, Insight Process Solutions has developed the Equilibar® ultra-sensitive back-pressure regulator. This patent-pending device provides the ultimate in precision vessel pressure control by venting excess gases.
This device can relieve high volumes of gas with only a fraction of a psi in
pressure deviation. The set-point is provided via a reference air
pressure, allowing for easy process automation. See how it it controls back pressure.
Dissolved Gas Removal
Bubbles are a major concern for most coating operations. Many established firms
have invested in complex vacuum systems to remove dissolved gases from their
coating solutions (a major cause of bubbles). However, a new generation of
separation technology can now extract virtually all dissolved gasses from your
coating solution in a simple, affordable module. Insight Process Solutions has
experience deploying this exciting technology to solve industrial coating bubble
In-Line Injection and Mixing
Pre-metered coating allows for the in-line addition of minor components into the
coating stream just before application. Using in-line injection, it is possible
to: Extend liquid batch life by removing cross-linkers, catalysts, and other
reactive components Reduce clean-up efforts by injecting latices and other
difficult to clean ingredients Control product variables in real time Expand
kettle capacity through concentrated prep and subsequent in-line dilution
Other Delivery Capabilities
We have experience throughout the solution prep and delivery process, such as:
