Uniplex III
High-performance control system for heating systems
Even in the latest version, the UNIPLEX heating controller of Klöpper-Therm will convince you due to development competence and future-looking technology in a single device. Developed especially for the control and monitoring of electrical heating systems, several function blocks are combined in a single device. The temperature controller, safety temperature limiter, and current controller are accommodated on a 19" plug-in card in European format in a space-saving manner.
Our innovation, your advantages
For you, this means:
- Almost no temperature fluctuations
- Cost reduction due to fewer lines and resistors
- Ready for changes in your production
