ERSA HOTFLOW 4/26 Reflow Soldering  Machine

The high-end reflow soldering systems of the Ersa HOTFLOW 4 series distinguish themselves by providing excellent thermal performance and the best energy balance. With process lengths from 3.3 meters to over 7 meters, respectively 8 to 26 heating and up to 4 cooling zones, the systems of this series cover all applications calling for economical reflow soldering with the highest throughput and the lowest energy and N2 consumption. Naturally, the traditionally high solder joint quality achieved with Ersa systems, the optimized process control and the necessary process stability are being maintained, while still offering a very high degree of system uptime.

The newly developed, smart Nitrogen control system substantially reduces the consumption of this costly consumable, offering, in conjunction with the efficient blower motors, a total reduction in energy use of more than 25%.

In the relation footprint to productivity, the HOTFLOW 4 series redefines the industry standard. Thanks to the dual- or triple conveyor option, the throughput can be substantially increased without enlarging the footprint. And to achieve the maximum in flexibility, up to three different conveyor speeds can be programmed.

Ersa HOTFLOW 4 systems can be equipped with multiple chain conveyor systems, with pyrolysis air cleaning, and with a number of different cooling options.

To ensure the maximum availability of the system for production, only high-grade materials and components are being employed, and much attention has been paid to the requirement that all important components should be able to be replaced within a few minutes.
