BEST SUITED FOR ALL KINDS OF PROCESS GASES AND PARAMETERS The uniqueness of the Laby®-GI Compressor is also reflected by its flexible performance range allowing very simple operation and control. No other compressor can be operated as efficiently over such a wide range of process duty parameters. For example, the discharge pressure necessary for fuel gas system supply, is automatically available independent of: - Alternating suction gas conditions: ■ Temperature (neither pre-heating of the gas nor pre-cooling of the compressor is necessary) ■ Pressure ■ Composition (e.g. N2 content in...
