Leister Process Technologies offers the right high quality tool for all areas in which plastics are processed. Whether for welding plastic waterproof roof sheeting, earthworks or tunnel engineering, in process equipment manufacture, for processing tarpaulins, for floor coverings or vehicle repairs. We have the appropriate tool for every field of application. - Such diversity is only offered by Leister!

The proverbial performance and reliability of our products makes us the first choice

  • Better hot air processes - Because air volume and heating performance can be set independently, precisely and reproducibly from each other.
  • Up to 60% higher blower performance - Because the frequency converter lets the blower turn faster than the mains frequency
  • Lower system costs - Smaller and cheaper blowers can be used or fewer blowers will be necessary, because multiple air heaters can be connected to a blower.
  • Easy to integrate in the controller - By the remote control interface 4-20mA/0-10V or by fixed set values (up to 4) via clamp contacts.
  • Air supply controller - Active braking function enables quick air volume changes, i.e. for timed systems.
  • Save energy – heat only when necessary - There are timed processes, where hot air is necessary within a clearly defined time window. For the rest of the time, the air volume can be minimised and the heating performance switched off.
  • Simple plug & play installation - The frequency converter is already configured for operation with Leister blowers.
  • Secure - Integrated current monitoring and a built-in motor protection switch protect the blower.
  • Elimination of the motor condensator - This function is already integrated in the frequency converter.
