Industrial automation allows precise control of all stages of pellet production, from the feeding of raw material to the packaging of the finished product. This makes the production process efficient and reliable. WALW’s proprietary software for controlling the pellet line provides intuitive operation and full control over the production process. This makes it easy for operators to monitor and optimise machine operation. This minimises the risk of breakdowns and downtime, ensuring production continuity. WALW automation systems can be easily integrated into existing production management systems, allowing the entire process to be centrally monitored and controlled. This allows better management of resources and a rapid response to any irregularities.

The standards we meet

  • Low Voltage Directive (2014/35/EU): It concerns the safety of low-voltage electrical equipment
  • EN 61439-1:2019 and EN 61439-2:2018- Applies to low-voltage control cabinets and their assemblies. Specifies requirements for construction, performance, testing and documentation
  • EN 60204-1:2021- Specifies electrical safety requirements for electrical machines and equipment

The professional control cabinet and its advantages

  • Free-standing control cabinet with high IP 66 protection for electrical components
  • PLC - Siemens S7-1200 - allows for complete freedom in configuring and upgrading the line
  • HMI Weintek 10" - allows intuitive control and constant overview of line operating parameters
  • Ethernet switch - remote access to control from any computer or smartphone
  • Inverters from a renowned manufacturer - for soft starting of large motors and precise speed control of feeders. They avoid overloading the network and reduce current consumption.
  • Other motors started by contactor starters - EATON
  • Safety system using EUCHNER safety relay and safety contactors - ensures line safety compliance with current safety standards
  • Lighting in the cabinet - for the service
  • Cabinet heating - heats and dehumidifies the air in the control cabinet extending the life of components

Possibility to manage production from the application installed on the phone.

Control cabinets installed on the granulator frame ensure simple, self-assembly of the line.

Manual and automatic operation mode.

The cabinets have customer Internet connectivity and a unique operating system that is user-friendly.
