ACU Air Control Unit
Pneumatic Conveying Systems
Adjusts valve opening and air flow from pipeline pressure – the most material with the least air.
Design data
- Used for
- Dense phase conveying; tanker unloading
- Main components
- Control valve (PIVC) / pneumatic panel / field control box
- Control
- PID module with 0–99 parameter sets; PLC / HMI interface
- Safety
- Automatic anti-blocking; shuts down if a blockage persists
The Air Control Unit (ACU) is used in dense phase pneumatic conveying. Where pressure is high and gas velocity and volume are low, with material moving in plugs, the ACU automatically controls the gas supply to keep velocity and flow stable.
Features
- Adjusts valve opening and air flow from pipeline pressure – the most material with the least air
- PID module stores parameter sets 0–99 for different materials and duties
- Detects an imminent blockage and boosts gas flow instantly to clear it
- Reduces pipeline vibration caused by pressure fluctuations
- Lower gas consumption saves energy
- Shuts down automatically to protect the system if a blockage cannot be cleared
Applications
- Dense phase pressure conveying systems
- High pressure, low velocity, low gas volume duties
- Plug-flow conveying
- Plastic pellets sensitive to breakage and streamers
- Tanker unloading systems – up to 40 t/h
Main components
01
Control valve (PIVC)
Adjusts the conveying air volume.
02
Pneumatic panel
Pressure and flow transmitters provide the control signals.
03
Field control box
A built-in PID controller sets the control valve opening from the pipeline pressure.
