Intelligent control technique
The electrical system with intelligent control technology is the heart of every extraction system. It automatically ensures safe and energy-efficient operating processes so that the customer's requirements and expectations with regard to operating costs, availability, operational safety, ease of operation and information needs are met.
The following control, monitoring and regulation functions are examples of the overall process:
Automatic and controlled activation and deactivation of the entire system
- Automatic opening and closing of the lock slides
Speed control of the extraction fans
- Speed adaptation of the transport fans
Minimum air speed in the piping system
Degree of contamination of the filter bags
Switching on and off of conveying systems based on demand
Residual dust concentration in the return air
Spark detection and -extinguishing
Threshold values of differential pressures
Development & Production
SPÄNEX has recognised the importance of the electrical control system for the functionality, energy efficiency and user-friendliness of the systems from the very beginning and has therefore set up a development and design department as well as its own control system production. In the development and design department, the switch system is planned and designed by an experienced team using CAD systems (e.g. E-Plan, WSCAD) and the production documents including detailed documentation are prepared.
The control systems are based on SIEMENS PLC devices (LOGO! or S7-1200) with different touch panels. With the S7-1200 in particular, additional functions are possible, such as visualisation of the system, Sm@rt service, integration of the SPÄNEX control units into the customer's internal network, e-mail dispatch in the event of faults or limit value overruns and service via remote maintenance. The power and control elements are installed in Rittal switch boards.
In the control unit construction department, we manufacture and test the complete switch boards. The power elements, switching and control elements are installed in Rittal switch boards, whereby special equipment and designs (stainless steel) are also possible. In addition to Rittal and SIEMENS, other quality products from Danfoss, EATON and ifm Electronic are used. Naturally, all elements are connected in accordance with standards and tested during commissioning.
All control units are planned individually for each customer and thus tailored precisely to the conditions of each individual case.
