Emotron FDU 2.0 Variable Speed Drive

6.1.3Compressors
Challenge Emotron FDU solution Menu
Compressor is damaged when cooling media
enters the compressor screw.
Pressure is higher than needed, causing leaks,
stress on the equipment and excessive air use.
Motor runs at same speed when no air is compressed.
Energy is lost and equipment stressed.
Process inefficiency and energy wasted due to e.g.
the compressor idling.
Overload situation is quickly detected and safety
stop can be activated to avoid breakdown.
Load Curve Protection function detects deviation.
Warning is sent or safety stop activated.
PID continuously adapts to the level required.
Sleep function activated when none is needed.
Load Curve Protection quickly detects deviation.
Warning is sent or safety stop activated.

Difficult to compensate for pressure fluctuations.
Wasted energy and risk of production stop.
Motor runs at same speed despite varying
demands. Energy is lost and equipment stressed.
Process inefficiency due to e.g. a broken damper, a
valve not fully opened or a worn belt.
PID function continuously adapts pressure to the
level required.
PID continuously adapts air flow to level required.
Sleep function activated when none is needed.
Load Curve Protection quickly detects deviation.
Warning is sent or safety stop activated.
