Marse RWFR 120 - High-Temperature-Compatible Water Flow Measurement and Regulation System for Mold Cooling and Tempering
Developed by Marse, the RWFR 120 Water Flow Regulator systems are professional 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 120 series is specifically optimized for closed-loop tempering systems operating up to 120 °C and delivers higher thermal resistance and process reliability beyond conventional WFR solutions.
RWFR 120 feeds multiple cooling lines through a central distribution manifold, ensuring controlled and continuous water flow in each circuit. This architecture balances temperature distribution within the mold, stabilizes cycle times, and significantly improves part quality repeatability.
Operating Principle and High-Temperature Compatibility
Marse RWFR 120 systems operate by distributing incoming cooling or tempering water into multiple zones via a central manifold. Flow adjustment and measurement components located on each circuit enable controlled and continuous regulation of water flow. The system is engineered to maintain measurement accuracy even under high-temperature operating conditions.
The core operating principle of RWFR 120 provides the following advantages:
• Stable flow control at temperatures up to 120 °C
• Full compatibility with closed-loop tempering systems
• Balanced and repeatable cooling across all zones
• Minimization of temperature fluctuations inside the mold
• Consistent heat transfer performance throughout the process
This design is especially critical in applications involving engineering plastics, glass-fiber-reinforced materials, and tight-tolerance parts.
