The new environmentally friendly DriTech thoroughly dries even the industry's most challenging pastes and does so with no VOC contamination of the equipment or the environment. DelSolar will utilize their DriTech for aluminum paste drying, the process step that produces the highest volume of contamination and by-products.
"DelSolar is committed to producing high performance solar products, with minimal environmental impact. We achieve this by selectively investing in technology and innovation and continuously enhancing our state-of-the-art equipment," states Mr. Lidon Chen, DelSolar President. "DelSolar believes that the DriTech offers the industry's leading solution to the challenges associated with aluminum pastes and contamination. The environmentally friendly tool requires almost no maintenance and needs no by-product treatment or disposal. The advanced process tuning capability of the DriTech will provide us with the opportunity to process new pastes and to truly optimize our drying performance."
The unique design of the DriTech decouples the VOC removal and binder burn-off for a more efficient drying process. A centrally located point-of-generation thermal oxidizer provides maintenance-free VOC abatement and ensures that the chamber remains free of contaminates, and that smoke and solvent do not leave the ends of the dryer. DriTech airflow is managed to reduce cold air entrainment at the entrance and exit. The DriTech is designed for a fast peak thermal profile that delivers lower wafer exit temperature and maximum VOC release at an early stage, resulting in higher paste drying efficiency. The tool also features a compact design and significantly smaller footprint.
"We developed the DriTech in response to the industry's need for clean, flexible and efficient drying equipment that can accommodate next-generation pastes; and to provide our customers with the ability to truly optimize the performance of each individual drying step in the production line," states John Farrell, Managing Director of Despatch's Solar Business Unit. "The environmentally conscious design of the equipment provides built-in VOC abatement for environmental cleanliness and eliminates the contamination issues that have historically impacted drying. We are very pleased that DelSolar selected DriTech and we look forward to our continued partnership with them."
