MATERIALS / RECYCLING PETplanet Insider Vol. 24 No. 09/23 www.petpla.net 10 Launch of New Generation Dryer range Italian company PET Solutions has announced the launch of a new range of dryers, branded New Generation Dryer DR-RE Series. PET Solutions says that the new range delivers improved performance across a range of parameters, including higher levels absorption capacity, while improving energy recovery by 25% and reducing consumption by around 15%. Risks of inadequate dehumidification PET is susceptible to moisture absorption from the surrounding environment, which can undermine its mechanical and optical properties. The particular issues PET Solutions lists are: Loss of mechanical strength leads to increased material brittleness. This could result in damage during handling, transport or package opening, raising safety risks and incurring higher costs. Variations in optical properties such as transparency and brilliance, caused by trapped moisture, can affect the aesthetic appearance of packaged products, influencing consumer experience and quality perception. Moisture within PET can lead to problems during the production process, such as bubble formation or surface defects. These can compromise the structural integrity of the packaging and affect its functionality. Moisture can catalyse chemical reactions and lead to degradation of polymer chains. This could impact the chemical stability of the material and even cause the formation of unwanted substances that could interact with the packaging’s contents. Effective dehumidification and proper treatment of PET will help to retain its desired strength, durability, and optical properties. A higher quality end product will result in more attractive packaging, with positive results for brand image and customer experience. Reducing moisture-related defects simplifies production processes and reduces production interruptions and the cost of downtime and repairs. PET Solutions’ New Generation Dryer DR-RE series PET Solutions says that its new range of dryers represents a significant step forward in material processing and establishes new standards for efficiency, performance and stability. The latest iteration of the New Generation Dryer series includes a brand new patented process characterised by the blowers positioned after the dessicant towers in the air process circuit. This location is said to deliver a cut of 15% in blower-related energy consumption. Reduced energy usage makes the new range suitable for environmentally responsible production facilities. What the company describes as a “sophisticated double filter system” is claimed to deliver a 47% increase in filtration capacity. PET Solutions says that this notable boost in capacity is more than just a statistic and that it indicates a substantial improvement in purity and cleanliness of processed rPET materials. In addition, the advanced filter system is claimed also to streamline maintenance operations and consequently further optimise production processes. The presence of a greater number of molecular sieves increases absorption capacity by up to 31 l per tower. This means that the number or regenerative cycles is reduced, while extending dessicant lifetime. The larger size of the exchanger within the dryer results in a 45% amplification in cooling capacity. This accelerates the drying process and ensures that PET and rPET being processed retain their optimal properties during transition from raw to finished product. PET Solutions says that the dryer offers greater throughput while maintaining material integrity, ensuring consistent quality output. The company declares that its New Generation Dryer achieves 25% overall energy recovery, which contributes to a more sustainable production cycle while eliminating the need for an oil condenser. The development is intended to raise standards for efficiency and performance in material processing. www.petsolutions.it New Generation Dryer DR-RE series The DR-RE dryer features a unique, patent-protected design.
