BLOWER UNIT

Our blower units generate the necessary conveying air in pressure conveying systems. All blower units were tested in our test plant for different conveying distances and line pipe cross sections.

The conveying air is sucked in filtered and compression is provided oil-free. This avoids contamination of the bulk material. Each blower is equipped for the connection of one or two fan bypass valves.

A pressure sensor detects the counter pressure at the blower outlet. This means that pressure-controlled conveyance is possible with our standardised controls.

Blower unit

The blower unit supplies the necessary conveying air for emptying silo vehicles or SeaBulk containers. Switching between these operating modes takes place using a “silo truck / sea bulk” switch.
For emptying SeaBulk containers, we also offer a mobile rotary valve station.

Functions:
  • Filling pressure monitoring (max. 0.8 bar); warning messages when exceeded
  • Automatic shutdown in critical pressure range
  • Key switch (system on/off); emergency stop (emergency shutdown of the system)
  • Start/stop push-button combination (switching the blower on and off)
  • Horn / flashing light combination (warning signal when pressure is exceeded)
  • Option: Control of a mobile rotary valve station for emptying SeaBulk containers
Installation conditions:
  • The system is only suitable for indoor installation in ventilated rooms.
  • The max. distance between the blower unit and the filling point is 20 m.
  • The max. length of the filling pipe at the silo is 30 m (of which 20 m vertical).
