Rehm Launches Low Maintenance Residue Management
Convection reflow oven that uses low-residue management system.
Blauberen, Germany — Rehm Thermal Systems has launched an advanced new flux residue management system that is deployed within the heating zones of the company's VXP convection reflow ovens.

Rehm Pyrolysis is the thermally induced decomposition of organic compounds. Complex molecules are broken down into simpler substances by the high temperatures (500 to 900°C) in a largely oxygen-free (anaerobic) environment that avoids burning.

According to the company, pyrolysis is the thermal splitting of long molecular chains into shorter ones, which significantly reduces the amount of condensable waste and unwanted dripping within the process chamber. The remaining residues are then captured within a special granulate. The system is reportedly nearly maintenance-free, requiring only an exchange of the granulate at 12-month intervals. The VisionXP's complete residue management system combines pyrolysis action mechanisms in the preheating and peak zones with cold condensation in the cooling zone. This way, both the amount of liquid residues and crystalline residues are dramatically reduced. As a result, the system reaches a higher efficiency than systems that use other techniques — by providing both a cleaner process chamber and greatly extended maintenance intervals.
