The GRELCI MARAS PULZON Series is a digital temperature controller engineered for the precise thermal management of hot runner systems in injection molding. It is designed to maintain optimal melt flow and part quality through intelligent automation and robust fault tolerance.

Key Operational Benefits

• Auto-Tuning Intelligence: The controller features smart self-optimization, automatically adapting its control parameters to the thermal load to maintain precise temperatures without manual PID adjustment.
• Built-in Resilience: A critical feature for demanding production environments is its ability to continue operation even with one or multiple defective thermocouples, minimizing downtime and scrap in multi-zone heating applications.
• Protection & Longevity: The soft start function protects heaters from the high inrush currents that occur during startup, extending the service life of heater elements and reducing the risk of electrical faults.

Applications

• Hot runner injection molding systems
• Multi-zone plastic processing equipment requiring precise and reliable temperature control
