Can you afford to waste efficiency by operating your compressor with an outdated controller? Unisab retrofit, HB/AAS/bbp | 12 May 2009 F:\RPC\Roadshow´\Unisab III\Unisab III retrofit HB-AAS

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. Unisab retrofit, HB/AAS/bbp | 12 May 2009 F:\RPC\Roadshow´\Unisab III\Unisab III retrofit HB-AAS
