FarragTech of Austria(U.S.office in Glendale Heights,III.)will feature its CARD(compressed air resin dryer)technology at K 2019,as well as internal blow molding cooling units.The CARD E/S,CARD M and CARD L/XL dryers and Blow Molding Booster and Blow Air Chiller internal cooling units will be presented during the show.The company notes that in extrusion blow molding,it was standard to vent the dry blowing air at the end of each cycle.Seeing this as wasteful,company founder Rainer Farrag developed CARD technology in 1991 to reuse the blowing air for resin drying.Since that time,FarragTech says it has made improvements,including better process integration and new controls,including a sleep mode.With sleep mode,the amount of air is reduced after reaching a set temperature in the upper range of the drying hopper.Heat recovery from the air compressor has further boosted efficiency.
