ERSA Hotflow 7 is a robust, reliable and high performance reflow oven designed to process lead or lead-free solder alloys. It is designed with a robust base to ensure optimal performance and long lasting use. Hotflow 7 has a wide working range, with temperatures ranging from 90°C to 415°C, which allows it to be used in a variety of different soldering applications. It also features an intuitive user interface, which enables users to quickly and easily control settings such as rate of ramp up, reflow point, peak temperature, and other soldering parameters. The oven also has multiple options for cooling, including natural or chimney-type cooling, forced-air cooling, and several types of PID controlled cooling. The latter two options improve the overall performance of the oven by ensuring that the parts are properly cooled down after the soldering process. This helps avoid damage and ensures a quality soldered joint. ERSA Hotflow 7 is equipped with a 10-zone heating zone mechanism which allows it to maintain consistent temperatures throughout the reflow chamber. This helps avoid "cold solder" spots, meaning solder joints which are not adequately melted and joints that don't have a sufficient connection. Hotflow 7 also has an advanced, PC-based data logging equipment, which enables users to track the temperature profiles during the reflow cycle. The data logging system also helps users optimize process parameters for successful soldering processes. Moreover, the data can be downloaded and edited if needed. In addition, ERSA Hotflow 7 has a conveyor unit that helps ensure that parts of different sizes can be processed efficiently. This conveyor machine is adjustable, allowing users to select from several different speed settings. Overall, Hotflow 7 is a reliable and efficient reflow oven which is capable of consistently producing high-quality and safe solder connections. Its wide temperature range and excellent data logging capabilities make it the ideal soldering solution for commercial and industrial applications.
