The 1809EXL- from Heller's newest generation of reflow ovens- provides 25% higher airflow for enhanced temperature uniformity, repeatability and high-load handling. The 1809EXL features Heller's new, enlarged heating tunnel and baffle-free design, for six-sigma consistency, zone-to-zone and oven-to-oven. It also provides more flexibility in board handling and robust construction. The 1809EXL supports high-speed, high-volume throughput… at speeds up to 40 inches (one meter) per minute… while conserving valuable factory floor space. Rapid response times and precise temperature controls assure process uniformity, regardless of component density or board loading, with identical profile performance in either air or nitrogen.
