Heat treatment process controller Optipac VMC-15

probemodularprogrammable

Overview
The Optipac VMC-15 from Mahlo GmbH + Co. KG is a modular process control system designed for textile drying and finishing. It measures, logs and controls key process parameters across the full working width to manage drying, fixing and stenter-related steps. The system enables reproducible process control, higher throughput and significant energy savings. Modular architecture allows adaptation to standard lines and customised installations. Integration with Orthopac weft straighteners is available to combine straightening and process control in one solution.

Product highlights

• Modular system architecture for scalable installation
• Operator-friendly touch-screen interface and ergonomic software
• Clear process visualisation and online monitoring
• Closed-loop control of temperature, dwell/fixing time, residual moisture, exhaust-air moisture, thread/course density and basis weight
• Designed for easy retrofit into existing stenter lines

Customer benefits

• Improved productivity and process reliability
• Enhanced reproducibility and quality comparability
• Comprehensive documentation and data logging
• Lower energy consumption and reduced operating costs
• Short payback times through efficiency gains

Area of application

• At the stenter frame
• In textile converting operations
• For drying, fixing and finishing processes

Sensors (examples that can be connected and used with Optipac VMC)

• Permaset VMT – infrared pyrometer for measuring and controlling web/surface temperature and dwell/fixing time (example range: 0 - 250 °C)
• Famacont PMC – optical thread-density sensor for weft density, course (stitch row) density and basis weight
• Ecomat AML – exhaust-air humidity sensor to measure water vapour, oxygen and exhaust-air composition for exhaust-air moisture control
• Gravimat FMI – beta transmission sensor for basis weight and thickness measurement
• Textometer RMS – residual moisture sensor using electrical conductivity to determine residual moisture at the stenter outfeed
• Wilot WMR – product width sensor using IR LEDs in reflex mode to record fabric width

Integration and software
The basic Optipac VMC unit comprises the main control cabinet with electronic control components and an operator station with touch-screen display. Optional software packages provide visualisation, logging (e.g. mLog) and process data management. The system supports online monitoring and closed-loop control and can be integrated with weft straighteners and pattern control systems to coordinate straightening, pattern control and process control.

Variants

• Stand-alone unit
• Integrated solution combined with Orthopac weft straighteners (straightener + process control)
