Details & Feature
The MARINER is designed for the toughest applications whether in continuous operation or in demanding environmental conditions. The three-stage design and industrial roller bearings ensure durability and smooth operation. The integrated drop frame provides reliable protection and allows easy expansion with accessories. Powerful, corrosion-resistant, and ideal for mobile and shipping applications. Perfect for compressing nitrogen.
Compressor control (PROFI-LINE)
The electrical control with monitoring electronics shuts down the compressor at final pressure, records operating hours and oil pressure, and displays the current status. It also enables fully automatic operation.
System design
The MARINER-GI series is equipped with a robust crash frame that provides reliable protection and allows for easy expansion with accessories. Thanks to its corrosion resistance and low-vibration design, the system is ideal for demanding operating conditions. The design is complemented by the newly developed fan wheel guard, which noticeably improves cooling performance through optimized cooling air flow.
Compressor block
Our compressor blocks are based on decades of experience and development. An efficient air cooling system with large coolers and finned cylinders ensures optimal cooling. Robust industrial roller bearings, pressure lubrication, and fine oil filters minimize wear. Dynamically balanced drive units ensure smooth operation and long maintenance intervals.
B-DRAIN automatic condensate drain
The B-DRAIN condensate drain automatically discharges the water-oil mixture from the intermediate and final separators. Solenoid valves control the discharge individually and reliably. The gentle, controlled condensate release reduces pressure losses, saves energy, and increases efficiency. Compared to conventional solutions, B-DRAIN operates significantly more quietly.
Drive
Power transmission is carried out via a low-maintenance, self-tensioning V-belt drive. Thanks to the integrated motor rocker, re-tensioning is not required. The compressor systems are equipped as standard with energy-efficient IE3-class three-phase motors, ensuring reliable and economical operation.
Options
Purification system
Depending on the system type, the compressors can be optionally equipped with the integrable P 61 or P 81 purification system. This allows pure air and gas qualities to be reliably achieved in accordance with ISO 8573-1.
Trolley set
The trolley set enables easy and effortless transport of mobile compressor units. Equipped with pneumatic wheels, it ensures maximum mobility.
