K 2019 / Farrag Tech Resin drying and more saves energy and costs
With his invention, the Economic Resin Dryer (ERD) in 1991, Rainer Farrag, Founder of Farrag Tech, revolutionised the resin drying process.
Resin drying carried out using adsorption driers to dehumidify plastic material was the tool of choice for most companies until the beginning of the 1990s. This procedure, however, required high acquisition, maintenance and energy costs. Furthermore, over time the result suffered from the continuously, decreasing performance of the integrated molecular sieve.
With his invention, the Economic Resin Dryer (ERD) in 1991, Rainer Farrag, Founder of Farrag Tech, revolutionised the resin drying process. It compressed air during drying and also enabled consistent product quality at low energy consumption. Over the years, the ERD technology was further developed and is used today under the name of Card (Compressed Air Resin Dryer). The dryer variants of the Card series can be combined with systems for condensing water and internal mould cooling, all of which allow for the entire process of plastic processing to be more efficient, the Austria-based company explains. The company will showcase its sustainable dryer technology at K.
Today, Card has a more efficient process integration and modern controls such as the Sleep mode. It also automatically reduces the amount of air on reaching a certain temperature in the upper range of the drying hopper, which provides for further reduction of energy consumption of the entire process. The heat recovery from the air compressor is now used for resin drying, the company adds.
Apart from pure resin drying, Card is also used in combination with other systems. For example, Card can also combine the dehumidification of the resin with internal cooling of the product. This way, material stress, which is caused by additional condensation water of the supplied exhaust air, is avoided. Subsequently, production could be increased by up to 35 percent at increased product quality, while lowering manufacturing costs, Farrag Tech claims.
At the K show in Düsseldorf, among the exhibits at Farrag Tech's booth are bulk material dryers — the Card E/S, Card M and Card L/XL as well as the internal cooling units from the company, namely the Blow Molding Booster and Blow Air Chiller. On hand to receive visitors will be Rainer Farrag's son, Aaron Farrag, who is also the managing director.
At the K show, Farrag Tech will be in Hall 12, Booth E 49-7.
