Problem

ROLOFOL a.s., a leading Czech producer of stretch films, operates extrusion machines that run continuously to meet demand in the packaging industry. One of its extruders, dating from 2005, had begun to experience reliability issues, with its existing Profibus-based drives becoming increasingly difficult to maintain.

Solution

Invertek Drives supplied two Optidrive P2 variable frequency drives (VFDs) to renovate the extruder systems.

The drives were selected for their high-performance torque control, ability to integrate into existing systems, and reliability in 24/7 continuous operation.

Industry: Packaging

Application: Extruder and product winding for stretch film production

Products Used: Optidrive P2

The Challenge
ROLOFOL a.s., a leading Czech producer of stretch films, operates extrusion machines that run continuously to meet demand in the packaging industry. One of its extruders, dating from 2005, had begun to experience reliability issues, with its existing Profibus-based drives becoming increasingly difficult to maintain.

For ROLOFOL’s maintenance team, sourcing spare parts and managing repairs was time-consuming and costly. Any downtime risked disruption to production, creating a need for a robust and modern solution to keep extrusion.

The Solution
Invertek Drives supplied two Optidrive P2 variable frequency drives (VFDs) to renovate the extruder systems - 2 × 110kW P2 drives for the extruder screws

The drives were selected for their high-performance torque control, ability to integrate into existing systems, and reliability in 24/7 continuous operation. The TFT display provided operators with clear visibility and control during production runs.

Results
- Increased reliability and reduced risk of downtime in extrusion
- Simplified maintenance with modern, widely supported drives
- Improved communication between operators and the system thanks to the TFT display and easy integration
- Greater confidence in maintaining high-quality film output

Why Invertek?
ROLOFOL selected Invertek after considering. Invertek’s fast response, ability to meet deadlines, and direct communication with the customer gave it the edge in a highly competitive environment.

Future Collaboration
Following the successful installation in mid-2025, ROLOFOL plans to renovate another extrusion machine dating from 2007 using Invertek technology, building on the strong partnership established.
