Boost your efficiency when high pressure matters. Our DM-Series reciprocating high-pressure piston compressors are ideal for compressed natural gas (CNG), natural gas vehicle (NGV) refueling and hydrogen applications. With maximum reliability and energy efficiency, our oil-less compressors boost your plant productivity.
The DM-Series oil-free piston compressor range delivers high pressures up to 350 bar (a) with outstanding safety and efficiency – important reasons why compressors have become a mainstay in demanding compressed natural gas and hydrogen applications across the world.
Completely gas-tight, the piston compressors are perfectly adapted to applications such as:
Our DM-Series compressors are equipped with oil-free cylinders, incorporating innovative Scotch yoke technology in a space-efficient vertical design. DM-Series compressors are absolutely gas-tight, thanks in part to a magnetic-coupling for the motor unit and hermetically sealed pressurized crankcase. This design offers you two-way protection: It prevents gas from leaking into the atmosphere and ingress of atmospheric air, providing maximum safety.
Further boosting your productivity, the single-acting compressors run on low per-stage pressure ratio with combined concentric inlet/outlet valves and single-acting pistons with small cylinder clearance. Completing the package, the DM-Series is shipped in a frame-mounted design for quick installation, while total independence from water consumption for cooling further minimizes your cost of ownership. DM-Series compressors are CE-certified machines.
The DM-Series is engineered and tested for a long service life and uncomplicated maintenance. Thanks to magnetic coupling design, the compressor block can be easily dismounted and replaced on site in less than a half a day. The dismounted compressor block will then be refurbished in the factory to guarantee the shortest downtime and maximum availability.
