Single screw extruder GL

compactfor energy savinglow energy consumption

Overview
The GL (gearless) extruder series provides an alternative drive concept. A frequency-controlled, high-torque AC motor drives the screw with the screw and the motor output shaft aligned in one line. The high-torque AC motor maintains high efficiency across operating ranges, including partial-load operation. Because GL drives operate without gears, energy losses associated with gear transmissions (e.g. flange loss, heating) are eliminated.

Your Advantages

• Minimal maintenance effort (no motor air filter servicing, no gearbox oil change), reducing operating costs
• Low noise and vibration levels in operation
• Improved drive-chain efficiency thanks to high-torque motor technology
• Smaller footprint with good accessibility
