Marse RWFR 160 - Water Flow Measurement and Regulation Systems for Mold Cooling and Tempering, Compatible with Temperatures up to 160 °C
Developed by Marse, the RWFR 160 Water Flow Regulator systems are advanced water regulation solutions designed for the precise measurement, monitoring, and balanced distribution of high-temperature water flow in mold cooling and tempering circuits used in plastic injection molding, blow molding, and extrusion processes. The RWFR 160 series is specifically engineered for closed-loop tempering systems operating at temperatures up to 160 °C, offering a level of thermal resistance and process reliability far beyond standard water distribution and flow control solutions.
RWFR 160 systems supply multiple cooling or tempering circuits within a mold via a central manifold, ensuring controlled and continuous flow in each individual circuit. This configuration minimizes temperature differences within the mold, makes cycle times more predictable, and significantly improves part quality repeatability. Especially in the production of engineering plastics and tight-tolerance technical parts, RWFR 160 systems make a direct contribution to overall process stability.
Operating Principle and High-Temperature Compatibility up to 160 °C
Marse RWFR 160 systems operate by distributing water coming from a mold cooling or tempering unit into multiple zones through a central distribution block. Each zone is independently controlled using its own flow adjustment and measurement components. The system is specifically designed to maintain measurement accuracy and mechanical stability even under high-temperature operating conditions.
The operating principle of RWFR 160 provides the following key advantages:
• Safe and stable operation at temperatures up to 160 °C
• Full compatibility with closed-loop tempering systems
• Balanced and continuous water flow across all zones
• Reduction of temperature fluctuations inside the mold
• Constant heat transfer performance during long production runs
These features make RWFR 160 particularly suitable for processes involving materials such as PA, PEEK, PPS, PC, and glass-fiber-reinforced polymers that require elevated mold temperatures.
