                                                                                                       61 - 152 cm (24" - 60")



DEL series electric dryer is affordable multitask tunnel dryer. With its segmental chamber design provides choice of productivity
speeds. The choice of belt widths (24" - 60") determines the max. curing element size. Compact transportation package foot print
lowers transport cost and provides easy floor access.
         Conveyor belt system driven by AC gear reducer controlled with frequency converter drive. Belt speed is readable on LCD
display. Remote belt speed adjustment possibility.
         Temperature true-on belt reading, PID temperature regulator control, independent heat chambers power supply and
temperature settings.
         Low energy consumption is assured with 100 mm insulated walls, efficient IR ceramics and segmental design. Exhaust of
fumes is gravitation type, while it do not affect temperature stability in heat chamber. Hot air adjustable flow with thermal
insulated drive provides great flexibility in curing.
ANY INK ON ANY SUBSTRATE CURING with DEL series tunnel dryer.
         As DEL series tunnel dryer combines 3 way of heating transmission it becomes universal for many substrates and ink
types. In general DEL's series dryer can work in 3 modes:
IR MODE explanation
         While Ceramic Infra Red heat elements provide heat as IR radiation transmitted directly into curing substrate. We
benefit from IR radiation with low heat losses spread into surrounding air in heat chamber. We can also fit our transmitted wave
length into the requirements of specific ink. Common mistake made by other manufactures is use of hight adjustment for IR
elements. The reference point for temperature sensing is lost in such situation and calibration must be done for each height level
separately.
HOT AIR MODE explanation
         Hot air is necessary for proper water and solvent ink curing. The flow amount and temperature is crucial in this process.
The air flow is transmitting energy from Ceramic panels IR radiation into convection of HOT AIR. For this mode the temperature
sensor will need offset for proper readings according to IR MODE.
MIX OF HOT AIR + IR MODE explanation
         In this mode we combine IR radiation with HOT AIR convection. By reducing air flow amount we keep IR ceramic panels
in higher temperature providing IR radiation. However we have also hot air low flow amount blowing. This configuration might
be used for transfer paper printed with plastisol ink curing. While substrate is highly temperature sensitive and ink demands
certain energy amount absorption to be cured.
