The Ersa Hotflow 3/20 is a large industrial reflow oven designed for PCB manufacturing processes. Manufactured in 2011, this model features a robust build with dimensions measuring 6265 mm in length, 1201 mm in width, and 1375 mm in height, and it weighs approximately 1900 kg. It operates on a 400 V power supply.
This reflow oven includes 20 convection heating zones, divided between the preheat zone with up to 14 modules and the reflow zone with 6 modules. Each heating module has an adjustable airflow of up to 500 m³/h, with rated power of 3.3 kW per module and 4.5 kW for the last module. The process zone offers a total length of 4840 mm, with 3725 mm dedicated to heating and 1115 mm for cooling. The cooling system consists of up to a two-level ambient air cooling zone.
The conveyor system supports a working width adjustable automatically and continuously from 45 to 516 mm, with a clearance height adjustable between +35 mm and -37 mm. It features a center support that can be adjusted automatically and continuously, and the conveyor speed ranges from 20 to 200 cm/min. The pin chain conveyor is selectable with pin lengths of 3, 4, or 5 mm.
Electrical specifications include a 400 V, 3-phase, neutral, and ground connection with a frequency of 50/60 Hz, and continuous operating power between approximately 12 and 16 kW. The oven is equipped with an exhaust system featuring extraction capacities of 300 m³/h at the system inlet and 400 m³/h at the outlet, both with monitoring functions.
The machine is equipped with multiple access panels along the side, facilitating maintenance and operation. A monitor and keyboard are attached to the side, serving as the control interface. The unit is clean and appears to be in good visible condition without obvious damage. Warning labels are present near the control panel and on the machine body, indicating safety considerations during operation.
