Plastics Extrusion
Multilayer Films
Issues:
- Purchasers of the film, typically the food industry, will not accept random lengths of film from their suppliers
- Purchasers require precise lengths – several hundred feet per roll
- Multilayer Extrusion machines use numerous variable speed drives
Problems Arise
- Any significant voltage variation, even for a small fraction of a second, can cause malfunction of drives
- Result can be hours of downtime and significant costs
- Significant scrap is caused - not possible to recycle material
- Short rolls have little or no value
- Scrap + Downtime = Loss of Profit Opportunities
Solution
- Active Voltage Conditioner (AVC) will correct voltage variations; voltage sags, voltage phase unbalance, 3 phase harmonics & voltage swells (option)
- AVCs can be applied to groups of machines, individual machines or a complete site - available in indoor or custom outdoor enclosures.
- AVCs available at low voltage and medium voltage to 36 kV
- AVCs have small footprint and very high efficiency
- AVCs can be located close to sensitive machinery
Benefits
- AVC allows process to continue
- Costly unplanned production stoppages are avoided
- Scrap material and emergency maintenance are reduced
- Profits are retained
- Payback period for AVC investment typically less than 12 months
