Compress is the Rosedowns press control system. It is designed to provide the optimum throughput and oil yields by continuously monitoring the press operation and regulating the flow of material into the press. Compress provides for automatic start ups and shut downs and protects the press from possible overloads and feed surges.
In Normal Operation the system maintains a constant feed rate to the press and because a press is a volumetric system this gives the most consistent results. However, if the feed material conditions vary such that there is no feed to the press or high main motor loads are developing then the Compress system will adjust the feed rate to protect the press whilst maintaining the optimum performance.
Compress V is the current generation of the system and is built on standard PLC architecture. The Compress V system employs a new control logic that was implemented following highly successfully trials. The controls have also been simplified and designed to be even more operator friendly, making routine operation, system set up and calibration very easy
Supervisors can set certain limits on what settings an operator may apply. All high load and response times may be altered to suit the particular operating characteristics of the plant.
Compress V also benefits from the addition of a data logging facility with graphical displays as standard. Remote access to the system is also available via a standard Ethernet network and can be accessed via a web browser on a standard PC.
A variant of the Compress system will also work with an inverter on the main press drive. This allows the speed of the press wormshaft to be varied so that it can be set to exactly match the plant operating capacity. This option is especially suitable for plants operating a single press or for the last press in a line in multiple press plants.
The Compress system is intended for a plant control room location and can be supplied as a retro-fit control package or as part of a fully integrated panel that comes complete with all press related starters, inverters, meters and overload protection. A separate remote panel can be mounted near to the press to provide operating data. If the Compress is attached to a network then it is possible to monitor the Compress and press operation on any PC with access to the network.
The operating interface can be supplied in English, French, Spanish and Czech. Other languages may be provided on request.
