West Control Solutions’ KS 94 industrial controllers have improved production quality at a spice extraction plant in Hagen, Germany. The controllers have enabledthe workforce to process recipes with high precision and have made possible an efficient decentralised process control system to serve equipment that is widelydistributed across the plant.

The plant uses CO2 gases to dissolve the spices and to enable the complicated extraction process. CO2 gas must be provided to a range of equipment across the site, at temperatures ranging from 30°C to 80°C.  

The KS 94 was used for this application, while a decentralised automation system across the plant could be created due to the KS 94’s compatibility with the Interbus network, which was used to connect 15 standalone KS 94 process controllers to the central supervisory computer and associated units.

The controllers were connected by an Interbus network to various input/output modules and numerous field transmitters and actuators to the central supervisory computer.

Thanks to the success of this initial prodution plant, further plants are being built.

Key benefits of product application

  • The KS 94 was chosen as it was found to offer excellent precision control and the opportunity to create a decentralised automation system across the plant.
  • All of the KS 94 controllers have a standardised interface, enabling users of all experience levels to quickly and effectively harness the powerful functions within the controller.
  • The ability to control the temperature and pressure of the CO2 with such precision improves capability for the plant, since high-pressure extraction for both liquids and solids can be applied with equal success, and fewer production stages are required.
  • The company found that wiring costs were reduced and overall maintenance processes were simplified.
  • The system proved popular with the operating personnel, with the day and night display settings improving readability and simple on-site operation.
  • The decentralised controllers run a powerful algorithm that handles the high workload resulting from real-time computation, relieving the central PC from handling this work alone.

Key products from West Control Solution include:

  • Temperature controllers (single-loop and multi-loop contollers)
  • Process controllers
  • Limit devices
  • Profilers and programmers
  • Digital indicators
  • Transmitters
  • Circular chart recorders (analogue and digital)
  • Paperless chart recorders

Controllers are available in 1/32, 1/16, 1/8 and 1/4 DIN sizes. There are also a number of DIN-rail-mounted controllers available. At the heart of all product designs from West Control Solutions is exact, accurate temperature control in easy-to-use products complemented with excellent reliability and durability.

West Control Solutions works with a global base of equipment manufacturers and end users. The products are ideally suited to challenging and tough environments such as industrial ovens, furnaces and kilns, plastics and extrusion. As the products offer excellent levels of precise control and accuracy together with being attractive instruments with strong aesthetic consideration during design they are often commonly used in laboratory, testing equipment and food and beverage applications.

The products are supported by a dedicated team of technical support specialists. The team has more than 25 years’ experience in temperature control instrumentation, specifically supporting products in industrial applications. This knowledge provides customers with complete peace of mind that they will be able to maximise the functionality available within the products even for the most complex of applications.

In addition to the core product offering there is also a customisation team that is available for those occasions where a custom controller will fit your requirements better than a standard product. In these cases, a comprehensive specification will be created, considering all requirements relating to the look and feel of the instrument, the format and functionality that is required. For the majority of customisation projects either a standard controller or a previous custom design can be used as the starting point for the bespoke design. This allows customers to benefit from reduced design and manufacturing costs, resulting in more customers to gain competitive advantage through unique designs and advanced functionality.
