Units for rotary vane, liquid ring and lobe vacuum pumps in packaging machines, laboratories, hospitals and industrial processes: operating temperature, running and vacuum hours, motor protection and vacuum cycles. For manufacturers we design custom units with display and ModBus communication. We also design custom electronic boards and can fit your vacuum pump or vacuum system with a capacitive HMI touch screen driven by a sequencer (a small PLC), at a much lower cost than a PLC with an HMI display.
Featured product
MCT403 temperature alarm with pre-warning
Monitors the actual temperature of the motor or pump with a Pt100 probe. It gives a pre-warning output before the alarm is reached and stops the motor with its 16 A main output.

Which unit protects a vacuum pump against overtemperature?
The MCT403, with Pt100 probe, pre-warning output, alarm output and a 16 A main output to stop the motor.
How is the cycle of a vacuum packer controlled?
With an XTDU302 multifunction timer or with the MTDS04 sequencer, which chains 4 times and 4 pauses.
How do I know when to change the pump oil?
With the XVDU071 hour totalizer, which switches an alarm output when the programmed hours are reached.
