An agreement between Conair Group Inc., Cranberry Township, Pa., and Kreyenborg Plant Technology, GmbH & Co., Senden, Germany, gives Conair rights to sell a co-branded infrared polymer dryer (IRD) to plastics processors worldwide. In fact, the first Conair-Kreyenborg IRD has already been sold to a sheet producer in Monterrey, Mexico.
The deal with Kreyenborg expands Conair's dryer product line to include technology that promises faster drying and reduced energy consumption in high-volume applications such as PET sheet and film. The contract with Kreyenborg is open-ended, according to Larry Doyle, vice president of global sales and marketing. It gives Conair rights to sell the IRD dryers into the worldwide plastics auxiliaries market. The machines will be sold and serviced through Conair's global network of representatives, service technicians and regional businesses.
According to the companies, because the IRD crystallizes and dries in one step, the technology is especially suited to processing PET regrind and virgin/regrind blends. For PET flake with initial moisture content of up to 1 percent, the IRD can dry to 0.03 percent moisture in about 15 min while consuming just 130 W/kg/hr (59 W/lb/hr), say its developers. This moisture level can be acceptable for many vented extrusion applications. Even lower moisture levels (down to 0.005 percent) can be reached with one additional hour of desiccant drying.
"IRD is one more tool --along with our conventional desiccant dryers, and the Conair EnergySmart two-stage and single-stage systems – that we can offer PET processors who are trying to meet objectives for energy efficiency, shorter drying cycles and better quality products," says Jamie Jamison, Conair dryer product manager.
