High Temperature Godet Rolls – for high performance fibres

Some unique yarn characteristics are made possible by impressive temperatures. High-performance fibres require temperature of extremely high level based on the fact that fibres like para-aramids have high glass transition temperatures nearing 370 °C.

Retech high temperature godet rolls have a heating power up to 400 °C.

TECHNICAL SPECIFICATIONS 

• Temperature: 60 - 400 °C
• Speed: up to 3000 m/min
• Roll diameter: 220 - 400 mm
• Roll length: 250 - 550 mm
• Supply voltage: 230 / 400 V
• Frequency: 50 / 60 Hz
• Installed Power: up to 24000 W

CHARACTERISTICS

• Multizone (3 or 4) induction heated
• Rotating (RTS) temperature transmission system
• PT100 temperature sensor (thermocouple optional) with monitoring sensor (for overtemperature protection)
• Special cooling systems for bearings and induction heater implemented

ADVANTAGES

• Accurate and precise surface temperature profile (for consistent yarn quality)
• Robust, simple modular design with installation from the front
• Low maintenance
• All electrical connections with “plug-in” facility
• No system balancing (roll exchange without rebalancing)
• No additional lubrication (lifetime bearings)
• Integrated cooling without additional cooling systems (water, oil mist, etc.)
• Supervision of temperatures to protect damage (IoT)
