Is DC/AC music to your ears?
Plastic Extrusion Companies using DC systems have saved thousands in energy costs, reduced running costs, reduced maintenance costs and increased flexibility through a DC to AC energy conversion.
Why you may want to consider change?
In the Plastics Market, using DC equipment was once the only option for high level speed control needed for Plastic extrusion. Annual inspection costs and spares can become expensive for your maintenance teams.Modern AC technology has now caught up, and ABB AC Drives and Motors can deliver the precision speed control you need without the need for these costly maintenance chores and without the need for encoder feedback.
Who can help?
As your local Drives specialists, Sentridge Control can offer you a free Energy Consultation to show you just what you would be saving were you to install the latest AC Variable Speed Drive (VSD) and latest efficiency Motors technology to regulate the energy consumption of your processes.
Our Process – Your Solution
As a dynamic and experienced engineered solutions provider, Sentridge Control has developed a seamless process for conversion of existing DC equipment to the latest AC Motor and ABB AC Variable Speed technology. It’s not just the lower capital costs of an AC system compared to a DC system that makes conversion attractive, there are other issues too. AC technology is more efficient than DC and through greater efficiency comes lower running costs and far less annual maintenance required.
There’s no need for annual replacement of brushes, filters or oil, no Commutator or wear checks and no need to stock spares.
With AC variable speed control, you will only consume the energy that the process actually requires. Heat loss is dramatically reduced, motors and pumps are slowed to an electronically controlled speed and they are also soft started and stopped. There are good space and noise savings too and the efficiency of your process is generally increased.
Typically, converting from DC technology to AC will save your process 20-30% in energy consumption. The conversion not only changes the active motors to AC but also the controlling variable speed drives.

A Blue-Chip client ran a line of 8 off 160kW extruders, but the current control of DC was obsolete and difficult and troublesome to maintain
A Leamington based plastics company using a Negri Bossi Moulding Machine needed to reduce production costs, but without compromising any of its daily manufacturing processes.
Atlantic Plastics of Bridgend, South Wales, part of the Talis Group, makes fittings for water utilities and the distribution market, including boundary boxes for domestic properties. The company wanted to cut energy costs for its production as well as improve its environmental credentials.
The largest extrusion machine at a plastics factory in Chippenham was unreliable and very energy hungry. The unreliability was caused by an extremely small drive pulley requiring frequent drive belt maintenance. APDS were asked to investigate how to increase uptime and decrease energy costs of this machine.
