uv ink combination dryer for Full auto screen printing line
TAMPRINTER TURBOSTAR CBS
The combination dryer series CBS, is a complete new modular design based on high volume jet-air technology together with energy saving UV systems. The Teflon coated conveyor system with vacuum under the belt will securely and scratch free transport the material throughout the dryer.
When used in combination with cylinder machines, the dryer inlet would start with a "fold down" belt segment that will allow the operator to access the cylinder at the machine exit side.
Optional a UV bridge can be placed over the dryer inlet segment. This initial UV source is used mainly to "freeze" sharp edge / small detail UV ink.
The heating sections are 2 m long segments. High-volume circulation fans create a focused high speed jet-air stream to the material surface. Precise temperature setting with variation Less than or equal to2 CELSIUS. The maximum temperature is limited at 90 CELSIUS. The heating sections can be completed with additional IR radiators. Such feature will decrease the ramp up time needed to bring the substrate to the set temperature.
A separate UV section holding 2 UV lamps, 170 W/cm. The UV lamps can be mercury, ferro or gallium doped. The UV lamps are controlled by electronic power units. These systems allow for stepless power settings per individual lamp between 30 and 100%. Due to a "soft start system" the life time of the UV lamps is prolonged with more than 30% compared to conventional power control units. Also when used in combination with modern screen printing machines, the "smart UV function" can be activated. This function will automatically reduce the UV power when the printing press is stopped. IR quartz filters with in-between jet-air cooling effectively decrease the substrate temperature when passing under the lamps.
The highly efficient cooling section can either take in fresh air from outside or can be combined with a "cold water / heat exchanger" system running cold air in a closed loop system.
The CBS dryer series are the most efficient jet-air conveyor dryers on the market today. They effectively dry solvent as well as water based inks and cure UV inks with minimum heat transfer.

The separated section: cool

The optional section:
One in the warm air operating mode
Combination dryer, used for
physical drying of solvent-based paints, there is a gradual decrease in temperature in the transition to the cooling zone
and tension is achieved on the sheet surface. The transit section
also serves the thermal
Separation of heating and active cooling zones.
For the alternative UV operation is

switchable UV lamps out of transit
A high flow of circulating air, exactly in the
Temperature controlled, transmits the
Energy for solvent evaporation. Exhaust air and fresh air
are kept in the by-pass.

The resulting compact

Nozzle cooling fields immediately behind

If the combination version
of the dryer is used for UV painting tasks, the

IR emitters can be installed on request
