Features HOTFLOW THREEErsa Reflow Soldering
Even more quality in soldering
With the HOTFLOW THREE, Ersa is making a clear statement for even more quality in soldering. An absolutely unique feature: the SMART CONVECTION POWER UNIT (SCPU®). The exclusively developed motor and control unit ensures an optimized soldering profile and thus even better soldering results. Individual zones can be controlled individually, enabling perfect adaptation to the requirements of the material and solder paste.
Variable transport system
The HOTFLOW THREE, available with 16, 20 or 26 heating zones, offers single-track and variable dual-track systems for transporting PCB widths of up to 686 mm (single track) or up to 2x 300 mm or 510 mm wide (dual track). All versions have a center support that can be optionally activated or deactivated. The HOTFLOW THREE also impresses when it comes to maintenance - servicing the cooling zone and cleaning the filter systems is simply carried out from the front.
Intuitive User Interface
The HOTFLOW THREE is easy to operate! Its industrial PC with touch screen and the intuitive ERSASOFT 5 make soldering program creation and management extremely convenient and future-proof. Thanks to the new, exclusively developed motor and control unit SMART CONVECTION POWER UNIT, the HOTFLOW THREE delivers exact process data from each individual zone.
