Used HITACHI / KOKUSAI DD-802V-H #293608648 for sale

HITACHI / KOKUSAI DD-802V-H is a top-of-the-line diffusion furnace and accessory package that is designed for demanding industrial-grade applications. It is a double diffusion furnace capable of reaching temperatures up to 1,450°C and can accommodate up to 3 stacked substrates up to 6" in diameter. Being quartz tube-based has allowed for very high thermal uniformity and reproducibility of over 80% across the furnace. It is equipped with a vacuum pump which is used to evacuate oxygen and other contaminants from the vacuum chamber and can be used to maintain a vacuum environment up to 30 mBar. The graphite heating elements are situated in a cylindrical configuration a pair of dual-blade isolated heating elements in combination with microprocessor-controlled PID temperature regulation. HITACHI DD-802V-H features a highly-sensitive, high-precision thermocouple temperature controller providing precise and repeatable N2/H2 profile management. The dual-blade element arrangement also allows for optimized cleaning atmosphere management allowing for optimal temperature uniformity. The heating system has also been designed to minimize thermal efficiency loss to produce rapid response temperature ramping, even with large substrate sizes. KOKUSAI DD-802V-H is equipped with an advanced LCD controller panel with a graphical display that is intuitive and easy to use. It has several safety features to protect from over-heating, open-circuit, and abnormal pressure alarm. Other features include multiple heating and cooling curves, programmable preheat cycle, auto-shut-off, gauge calibration and fine-tuning of parameters to ensure accurate diffusion results. This package also comes with a range of accessories such as a heater shield chamber, a nitride liner, element guards, and alarm buzzer. It also has an auto-leveling and door alignment mechanism to help ensure perfect centering and uniform pressure on the crucible when loading substrates. In conclusion, DD-802V-H diffusion furnace package is a premium package that provides reliable and repeatable results. With its highly-sensitive thermocouple and advanced LCD controller, tight temperature uniformity and precise substrate loading and placement, this package offers a wide range of applications. Its safety features and selection of accessories make it the ideal package for precision diffusion and advanced application processing.
