Used HELLER 1913EXLA #9301760 for sale

HELLER 1913EXLA is a reflow oven designed to automatically heat printed circuit board assemblies (PCBs) to the necessary temperatures to solder and complete components. The process of reflowing solder paste to board assemblies facilitates the removal of air during the soldering process and makes assembly more efficient and reliable. 1913EXLA is a combination convective and conduction reflow oven with a simple and reliable design, resulting in minimal maintenance and easy operation. It can accommodate up to a 13" x 19" board size. The conveyor equipment consists of formed stainless steel mesh with a variable speed drive. The motorized mesh belt transports the PCBs along the reflow process, allowing for even and repeatable heating. The oven temperature profile is controlled using a PID algorithm which allows the user to define up to 6 temperature zones and 6 dwell times. The entire conveyor from roller to roller measures 38" and the total heating zone length measures 24" (including the cooling zone). HELLER 1913EXLA is a dual air circulation system with top and bottom air recirculation fans that evenly distribute heat across the entire conveyor. The top recirculation fans are located at the top side of the oven and each have a power of 1.1kW. The bottom recirculation fans are located at the bottom of the oven and each have a power of 0.4kW resulting in total combined air recirculation power of 3.2 kW. The oven, with its dual air circulation unit, ensures temperature homogeneity across the entire oven chamber and is designed for rapid thermal recovery from the door being opened. A forced air cooling machine is used to cool the PCBs' soldered components while on the exit conveyor and is included in the design. 1913EXLA is a digital reflow oven and is controlled by a full-color 5.7" touchscreen panel with a simple user friendly interface. The user can control all aspects of the oven's performance from temperature setting and timed dwells to conveyor speed. The user can save up to six profiles on the oven's memory and select them for future use. The oven can also be connected to a PC using an Ethernet connection and the user generate reports with the generated reflow profiles. All of these features make HELLER 1913EXLA a reliable and robust reflow oven designed for efficient soldering of PCBs.
