Retrofit kits will be available for upgrading existing EconoRed dryers with adjustable exhausts. Vastex EconoRed™ conveyor dryers are now equipped as standard with an adjustable exhaust for optimising the curing of printed textiles, DTF films and/or powdered adhesives, while cooling the skin of the enclosure and minimising wasted heat.
Using a damper control knob, the user can adjust the volume of exhausted air from 100% to 10% to remove all fumes emitted in the heating chamber according to the size, weight, throughput and ink type of DTG and screen printed garments, and/or the dwell time needed to cure powdered adhesives of DTF images or screen-printed transfers. Excess airflow unnecessary for exhausting of fumes is diverted and filtered to cool the double-wall skin of the heating chamber for worker safety.
Together with digital control of heater temperatures in one-degree increments and variable belt speeds from .55 to 7 metres per minute, the adjustable exhaust allows operators to fine-tune all critical drying parameters on a job-to-job basis, while accommodating the differing exhaust requirements of systems having multiple heating chambers.
The adjustable exhaust is available on all EconoRed Series II and III high capacity dryers in belt widths of 76cm, 137cm, and 198cm. All can be configured as new or retrofitted with additional heating chambers to double or triple curing capacity (belt speed) of screen printed plastisol inks, water-based inks and discharge, DTG pretreatment and printed images, and powdered adhesives of DTF substrates and screen printed transfers.
