TwisTorr Medium-TMP onboard Controller

The Medium-TMP onboard controller is a solid-state frequency converter driven by a single chip microcomputer. It consists of a PCB including power supply, three-phase output, analog input/output section, microprocessor, and digital interface section. The power supply, together with the three-phase output, converts the single-phase AC mains supply into a three-phase, low voltage, medium frequency output required to power the pump. A remote host computer can operate the controller via the serial connection. Optional Windows-based A-plus software is also available. The Medium-TMP onboard controller can be mounted onboard, on the bottom or using an optional bracket on the side, of the TwisTorr 704 FS and 804 FS pumps.


  • Drives the TwisTorr 704 FS and 804 FS pumps, the vent valve, and the cooling fan.
  • Universal voltage, the controller can auto set according to the input voltage, providing flexibility for easy installation worldwide.
  • Three-dimensional pump control software provides maximum flexibility, speed, and simplicity – always the best throughput and compression performance according to pump operative conditions.
  • RS-232/485 communication protocols and Profibus through optional converter.
  • Allows the pump to interact with the system controls (remote I/Os).
  • Enables the pump to be operated via PC with A-plus software.
  • Allows development of own customer software.
  • Normally open vent valve drive.
