A small compressed-air dryer for micro-parts injection molding is one of the new drying developments on display next month at the K show in Düsseldorf. Motan-Colortronic of Germany (U.S. office in Plainwell, Mich.) will bring out the Luxor CA S line of small dryers with hopper volumes of 0.75 to 5 liters. These compact, machine-mounted units come with a thermostat and low-air-flow safety switch to prevent overheating the material.
In addition, Motan-Colortronic is now offering its ATTN automatic temperature and dewpoint control as an option for all its Luxor A dryer series. It reportedly holds dewpoint within ±1° C.
Another new dryer at the show is the Drymax Aton2, a further development of the segmented wheel dryer from Wittmann Battenfeld (U.S. office in Torrington, Conn.). New features include thermal energy refeed via the 3-Save Process. This reportedly takes only what is needed from regeneration energy in order to dry the molecular-sieve desiccant in the wheel’s segments. This energy also provides a certain amount of heating of process air. If a limiting value for dewpoint is set, the dryer automatically optimizes the drying process through its EcoMode.
New from The Conair Group, Cranberry Township, Pa., is the DC-T TouchView dryer control (pictured). It will be shown as part of a central drying cell that includes a W300 Carousel Plus desiccant dryer and a four-hopper ResinWorks system equipped with Conair’s Drying Monitor. The DC-T has an 8-in. graphical touchscreen that shows everything going on in the drying system, as well as historical temperature data and trending graphs. It also handles dewpoint control. Up to 15 hoppers equipped with Conair temperature controls can be linked to the DC-T for monitoring and control.
