Wet Processing Center
Process foil with immersion, spraying, heating/cooling, agitation and electrochemical treatments in a fully enclosed, zero-emission system.
Precision Wet Processing for Roll-to-Roll Foil
The Wet Processing Center is a component for the Laboratory Roll-to-Roll Coater that enables accurate roll-to-roll handling of foil in a fully enclosed, safe environment. Designed for research, prototyping, and pilot production, it supports immersion, spraying, and electrochemical treatments for thin-film technologies, printed electronics, solar cells, and other advanced materials.
Immersion and Spray Processes
The system allows full liquid immersion for etching, washing, coagulation, imbibition, and ion or solvent exchange. Spray treatments apply liquids across foil surfaces while washings are recovered or safely discarded, offering controlled and efficient processing.
Electrochemical Treatments
Built-in electrochemical functionality provides heating, cooling, and agitation, while foils can be electrically connected with counter electrodes for various surface treatments.
Handles Extensive Chemistry
All Non-Oxidizing Acids
All Bases
Glcohols
Gliphatic Hydrocarbons
Vegetable and Animal Oils
Biological Agents
Aqueous Salt and Detergent Solutions
Modular and Scalable Design
Processing tanks can be linked for sequential treatments such as etching, developing, stripping, and washing. Configurations include direct docking with the Laboratory Roll-to-Roll Coater (10 L) or stand-alone systems (50 L). Processing lengths range from centimeters to five meters, and a variety of rollers supports integration with ovens, coaters, knives, and laminators.
Safe, Clean, and Durable Operation
Closed-system operation ensures zero solvent or liquid emissions. Double-sided air knives enable rapid drying, and high-quality plastics, ceramics, and stainless steel (316L) ensure long-lasting chemical resistance.
Integration with the Laboratory Roll-to-Roll Coater
Designed to integrate seamlessly with the Laboratory Roll-to-Roll Coater, the Wet Processing Center provides a compact, versatile solution for lab and pilot-scale thin-film applications. Modular components allow customization for batteries, medtech, fuel cells, printed solar cells, sensors, and more, enabling optimized performance with flexibility and scalability.

Wet Processing Center
Wet Processing Components
The essential part of the Wet Processing Center is the tank that holds the liquid, the rollers and all the auxiliary products such as stirring, cooling, heating, circulation, ventilation in a pseudo sealed container.
The Infeed-Outfeed Rollers can be designed as self-centering or straight and can be electrically connected to circuitry for electrochemistry or electrically insulating. The rollers feature 316L stainless steel bearing holders, equipped with either stainless steel or ceramic bearings.
In the Wet Processing Center, handling foil immersed in liquid requires that the rollers and their bearings are also submerged. Our chemically inert immersion rollers provide reliable and smooth foil transport while fully immersed, ensuring safe and efficient operation.
Blowing air or inert gas onto both sides of the foil, directed toward the Wet Processing Tank, effectively prevents emissions from escaping. This creates a pseudo-enclosed environment that is safe, contained, and adaptable for various processing needs.
The electric heating coil enables precise temperature elevation during wet processing, which is often critical to achieving optimal results. It is constructed with Teflon lines and stainless-steel heating elements, ensuring reliable performance, durability, and efficient heat transfer.
Wet processing of foil by immersion in liquids requires effective mixing and precise control of the intended contact time. Mechanical stirring is the most efficient method to achieve these objectives.
Enhance your thin-film drying process with the compact Dual-Sided Inert Gas Oven. Featuring precise PID temperature control and flexible gas flow options, it's ideal for fast, consistent drying in research and pilot runs.
