Applications

In industrial processes a blower often supplies several air heaters in parallel. It excels through its high power and compact design. The durable and maintenance-free blowers are a result of uncompromising quality standards and decades of experience.  The proverbial performance and reliability of our products makes us the first choice

Featured Benefits

  • 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.
