HES Series

Delta's Hybrid Energy Saving (HES) System provides precise pressure and flow controls for each injection molding process and also solves the energy waste issues of a traditional injection molding machine. This solution helps to improve product quality, market competitiveness and productivity.
 

Ultra Energy-Saving

• Saves up to 75% power consumption depending on the different injection conditions

• Energy Consumption Curve of the Injection Molding Process

(2) Excellent Overload Capability

• All HES-C models feature overload capability of max. pressure 175bar for 60 seconds, and some of the advanced models can reach max. 8 minutes. All these models are especially suitable for thick products production. Please refer to the Pressure-Flow Characteristic Chart on the following pages for more details.

(3) Cost-Effective System

• Delta Hybrid Energy Saving System HES-C adopts Hybrid Servo Drive VFD-VJ Series and Fan Cooling
• Servo Motor MSJ Series, and features high torque and low inertia. This allows users to select the Hybrid Servo Drive VFD-VJ Series and Servo motor MSJ Series with lower power ratings to save system cost.

(4) PID Pressure Control

• Using Delta's special PID control technique, the system is able to perform pressure overshoot under 3 bar with optimized response time and stable product weight.

(5) Field-Weakening Control of a Motor

• Delta's servo drive uses motor field-weakening control to effectively extend the motor operation
• scope, increase system flow and ensure productivity of the injection molding machine.

(6) Easy Commissioning

• Users can directly use the Delta preset motor and hydraulic system parameters without the need for additional tuning. 
• Simply install the drive to easily begin the operation.

(7) Excellent Performance

• Short response time enhances response speed of the system
• Great V/P transfer capability elevates product yield rate
• Lower noise compared with traditional dosing pump
• Stable oil temperature rise

(8) S-Curve Control

• Smooth operation reduces machine vibration

(8) S-Curve Control

• Smooth operation reduces machine vibration

(9) Multiple Protections

• Multiple protection functions, including over current, over/low voltage, over heating, brake protection,
• insufficient pump oil protection. Complete protection prevents the equipment from anomalies and
• serious malfunction, and enhances system lifetime.
• Real-time monitoring of the motor temperature is via a KTY84-130 temperature sensor embedded in the motor winding.

(10) Multiple Pumps Control

• Capable of controlling up to 12 pumps and multiple master/slave pumps system architecture. Users can integrate systems with a different HES-C flow rate depending upon the system requirements of the machines.

(11) User-Friendly Software

• User-friendly software for machine commissioning.
• The software presents real-time system parameters such as pressure, flow, motor current and motor speed.

(12) System Monitoring and Controller Integration

• Built-in PG and communication card, and USB port to connect industrial 3G routers for system monitoring and software upgrade.
• Supports CANopen communication protol, enhancing integration with the controllers
