ROPEX RES-408 Resistron:

RES-5008 ... replaces the obsolete RES-408 | USA

The ROPEX Resistron RES-408 controller utilizes microprocessor technology for sensorless, closed-loop control of impulse heating elements. The ROPEX RES-408 is designed for simple plug-in system integration.

The use of ROPEX Resistron controls goes beyond impulse heat sealers, form fill machines, and converting equipment. ROPEX Resistron controllers also provide a solution for an extensive range of heating applications:

  • Heat-seal-bands and cutting-wires ... for hermetic sealing, and trimming of flexible films

  • Zebra and intermittent heat-seal-bands ... for skip seals and packaging ventilation

  • Impulse heating tools ... for activation of adhesives used in the bonding of non-thermoplastic materials

  • Flexible or rigid impulse blades ... for scoring, cutting, and bending of thermoplastics

  • Impulse heater coils ... for hot air bonding, and scoring of thermoplastics

  • 2D and 3D contour heat-seal-elements ... for custom shaped heat-sealing, and heat-seal plus cuttings

The ROPEX Resistron RES-408 contains the following features:
