These compact gas compressors handle methane
Atlas Copco
This company’s GG-VSD lubricated gas screw compressors (photo) are designed for dry biomethane and methane applications requiring pressure to 16 bars (232 psia). These single-stage compressors are both water cooled and directly driven. The use of a variable-speed drive and a highly efficient rotor profile allows these compressors to maximize flow while minimizing horsepower requirements, and this helps to regulate capacity and keep the inlet pressure constant during operation. The single-stage compressor design is frame-mounted and compact, making it easy to install with minimal floor-space requirements. The GG-VSD compressors comply with ATEX Zone 1 2 design requirements, says the manufacturer.— Atlas Copco North America, Pine Brook, N.J.
