2. Can you afford to waste efficiency by operating your compressor with an outdated controller?
Unisab retrofit, HB/AAS/bbp | 12 May F:\RPC\Roadshow´\Unisab III\Unisab III retrofit HB-AAS

3. The compressor controller as competitive advantage
The controller is the brain
of the compressor.
The controller determines the compressor efficiency, lifetime and communication skills.
It can turn a simple compressor into a highly efficient, long-lasting and talkative engine.
