Drives upgrade: why you should replace your converters

Upgrades & Retrofits | Marco Nottoli, 26 May 2020

In a tissue, paper or nonwovens facility the large majority of machinery, such as tissue machines, unwinders, winders and rollers, require the use of an electric motor.

A drive is the electronic device that harnesses and controls the electrical energy sent to these motors.

Many plants have old machinery equipped with obsolete drives, some dating back to the 1990s. These drives, once the latest in technological advancement, are now lagging behind when it comes to efficiency and productivity.

On the other hand, new drives offer superior performance, modular structure and easy maintenance.

Why upgrade your drives?

Ultimately, new drives provide plants with a number of advantages. This upgrade (as many other updates or plant retrofits) mean increased performance, functionality and optimization of energy usage. This is due to the fact that old drives tend to be fixed-speed, while new ones are Adjustable-Speed Drives (also known as Variable-Speed Drives) that:

  • Allow for the adjustment of speed based on machine load and without the need for recalibration
  • Reduce energy costs
  • Improve system reliability
  • Reduce wear and tear on the system, requiring less maintenance and repairs
  • Improve process control

In addition to this, new drives offer the following advantages:

  • Motion control
  • Improved fan, pump, and compressor functions
  • Integrated safety features that help plants comply with existing regulations
  • Terminals with positioning flexibility that can be plugged in 
  • Improved product quality
  • Push-through cooling
  • Improved energy recovery
  • No problems with spare parts availability

Best of all, the new drives will still offer the choice of cabinet or built-in options, both boasting a modular structure and easy maintenance.

What does it take for a drive upgrade?

Upgrading to new drives for all your machines is a relatively straightforward process for us. Prior to the upgrade, A.Celli conducts an onsite pre-engineering survey. Then, the process continues with the engineering and replacement of the drives, which are preassembled and prewired in one of our A.Celli workshops. The installation requires the modification of existing rewinder cabinets to ensure there is a good fit.

Electrical supervision will be provided during the installation, commissioning and start-up of the new drive system by three A.Celli technicians. Once start-up has been achieved, the new system will be monitored by A.Celli for seven days.
