We design equipment depending on the line (paint, substrate, type of line, etc.) and available energy (gas or electric).
Controlled supply and exhaust flows for safety (LEL)
Pyrometric control for reliable and even curing in all situations
Our chemists are at your service to determine the best IR or UV/EB technology
INFRARED
Gas and electric infrared dryers :
CSI develops on demand gas or electric IR tunnels to dry chemical or aqueous treatments on steel or aluminum coils running at highly variable speeds (from few meters per minute up to > 200 meters per minute) for gauges ranging from 0.2 to 2 mm.
This equipment uses high power density that can reach 700 kW/m² in some cases. Vertical or horizontal design, it can be integrated into a new line or an existing line that does not allow hot air alternatives.
The almost immediate response of IR technologies is a significant advantage for lines with various productions in order to reduce transitional phases as much as possible and associated production losses.
Infrared technologies also optimize power use by selecting radiation width according to the selected web width. This saves a significant amount of energy.
Finally, CSI dryers are designed for quick and efficient maintenance (panels mounted on drawers, easy access to wear parts, etc.).
High Density Electric Infrared Curing Tunnels :
CSI has developed a range of R6 high density curing tunnels to cure solvent or powder paints on steel or aluminum coils running at variable speeds (up to to 50 meters per minute) for gauges ranging from 0.2 to 2 mm.
These installations use high power density that can reach 500 kW/m² in some cases. Vertical or horizontal design, it can be integrated into a new line or an existing line that does not allow hot air alternatives.
CSI tunnels are adapted to LEL standards with full or partial separation of the IR emitters from the process air. The quantities of air injected into the process air can be regulated to optimize operation of the incinerators or other pollution control systems.
The almost immediate response of IR technologies is a significant advantage for lines with various productions in order to reduce transitional phases as much as possible and associated production losses. This feature, combined with one or more pyrometric control loops, allows for reliable curing and controlled changes in speed, size and thickness.
Infrared technologies also optimize power use by selecting radiation width according to the selected web width. This saves a significant amount of energy.
Finally, CSI curing tunnels are designed for quick and efficient maintenance (panels mounted on drawers, easy access to wear parts, etc.).
Low Density Electric Infrared Curing Tunnels :
Some applications do not necessarily require high a power density. CSI can offer low density IR gas or electric tunnels, or even panels to be installed by the user. These installations can still reach power densities of 150 kW/m² and benefit from the same advantages as high density solutions.
They can be used in solvent management and provide important reactivity during transitional phases or changes in speed, format or thickness. One or more pyrometric control loops can be provided to offer the greatest flexibility of use.
Power used can also be optimized by selecting the radiation width according to the selected web width.
Finally, CSI curing tunnels are designed for quick and efficient maintenance (panels mounted on drawers, easy access to wear parts, etc.).
Electric Infrared line side equipment :
Coil coating lines are often paired with product and/or cycle testing facilities at the line side or in the production laboratory.
CSI also offers this type of equipment in order to provide as much consistency as possible between production and testing of the applied substrates and products.
These IR conveyors are designed for any format from A5 to A3 depending on your needs. They allow you to carry out the same cycles as the curing tunnels and manage them in 4 manual or regulated operating modes. The regulated cycles are controllable by pyrometer or thermocouples depending on possibilities or user needs. Curves can be retrieved from the network or USB key to approve and archive each cycle.
Electron beams
Ebeam polymerization tunnels :
CSI was a partner of the first industrial line combining of the three IR /UV /EB radiation technologies in Europe.
Tightened regulations on VOC emissions, reduced energy consumption, gradual increases in the CO2 tax and product recycling require end users to look for more environmentally-friendly processes. Electron beam polymerization drastically reduces energy consumption (by a factor of 10 compared to traditional convection ovens), avoids temperature increase and consequently the need for water quench.
Zero VOCs emission (EB coatings are 100% dry solids) means no need for air treatment (incinerators !).
Finally, EBeam technology significantly reduces the space required for a process line and allows very high productivity.
CSI and its sister company RADSYS (www.radsys.eu) can answer all questions about this rapidly growing technology.
