For designing the system, Ersa was able to draw on their extensive know-how and a hoard of experience gained during the 25 years of Ersa’s excellent track record in building reflow systems. Numerous economical and technical solutions could be ideally combined, without compromising in any way the reliability and uptime of the system. At the same time, the high-grade materials and proven components expected to be found in Ersa equipment are specified, yet, should a component fail, the necessary ease of access to repair and service is available to facilitate these services.

There was no compromise made in the selection of the controller. The HOTFLOW 3/20e is equipped with a premium PLC controller, and it offers a PC with Windows 7 operating system as the user interface.

The comfortable system visualization simplifies programming and has all necessary operating and process data on board. The solder protocol, available in the standard program version, is built on the ZVEI standard, which is a pre-requisite for future traceability applications.

The HOTFLOW 3/20e enthuses not only because of its technical features and performance, but also on account of its very attractive price. Considering it all, and taking it together with its high level of machine availability, excellent TCO values and a quick ROI are assured.
