With more and more applications in the building automation sector requiring high performance, cost effective and easy to use explosion-proof control systems, Schischek provides the solution with the ExReg.
The ExReg control unit is designed to ensure smooth operation when controlling HVAC systems for variable air volume (VAV), pressure, temperature and humidity by minimising the number of separate components required.
Developed from the successful ExCos and ExBin HVAC sensor series used extensively in hazardous area locations including ATEX zones 1,2,21 & 22, the new ExReg control unit features a compact design which incorporates an internal proportional-integral-derivative (PID) control structure. The parameterisation process is easy to use and automatically achieved for standard applications. The system provides support, especially during the start up process, with many predefined settings and damper characteristics.
Features retained from the globally established ExCos and ExBin series include the elimination of intrinsically safe wiring, digital adjustment, actual value indication and LED status display. Designed for electrical and mechanical compatibility with market standards, the ExReg is suitable for 24Vac or dc supplies and environmentally protected to IP66.
