Details & Features
The MARINER-OX is one of the most powerful mobile compressors worldwide for compressing Nitrox and breathing air. Specially engineered for Nitrox mixtures up to 40% oxygen, it meets the highest standards of safety and quality. The integrated B-CONTROL MICRO control system with temperature monitoring of all stages and the final separator ensures maximum operational safety. The MARINER offers excellent performance while requiring minimal space - ideal for mobile use at dive centers or in the field. Its robust components and wide range of options allow for individual customization.
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.
P 41 filter system
The P 41 filter system with additional oil and water separator as well as pressure-retaining non-return valve ensures reliable breathing air in accordance with DIN EN 12021:2014¹ when using original BAUER filter cartridges. A type-tested, sealed final pressure safety valve ensures high operational safety. The processable air volume is 1,550 m³.
¹ Applies with proper maintenance, installation according to the operating manual, and when using the BAUER B-AEROGUARD if the CO₂ concentration exceeds the standard limits.
B-CONTROL MICRO compressor control system
The B-CONTROL MICRO is a modern, user-friendly compressor control system with a color display that intelligently manages and reliably monitors all basic functions. Interaction between the user and the control system is intuitive and straightforward, with information displayed in clear text. Various languages are available. External signal transmitters can be connected at any time, and operation in a networked system or with an external display is also possible.
Kompressorsteuerung B-CONTROL SMART
Die B-CONTROL SMART ist eine leistungsstarke Kompressorsteuerung mit erweitertem Funktionsumfang, viel Speicher und IoT-Konnektivität via B-CLOUD. Sie unterstützt den Verbundbetrieb und bietet hohe Performance für anspruchsvolle Anwendungen. Wahlweise mit 3,5" Farbdisplay oder 7" Touchscreen ermöglicht sie intuitive Bedienung und sicheren Fernzugriff – eine zukunftssichere Lösung.
Crash frame incl. carrying handles
The corrosion-resistant crash frame provides additional protection and space for accessories such as compressor control or larger filter system. The carrying handles ensure easy and comfortable transport.
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.
Temperature monitoring in final separator and cooling air
All BAUER B-NITROX compressors are equipped with temperature sensors to monitor cooling air and the final separator, ensuring safe operation. The sensors reliably control compliance with the specified operating temperatures.
Filling device
The filling device consists of a flexible "UNIMAM" high-pressure filling hose and a filling valve with a final pressure gauge. The gauge allows easy reading of the filling pressure and is reliably protected against damage by a robust rubber coating.
Filling hose
The high-quality UNIMAM high-pressure filling hoses are made of food-grade, durable material and provide maximum flexibility during handling. Swiveling hose connections allow for quick, easy, and safe connection of the filling valve to the breathing air cylinder.
Motor rocker with belt tensioner
Thanks to the integrated motor rocker with belt tensioner, no retightening of the V-belt is required anymore.
Options
B-SECURUS filter monitoring
The B-SECURUS system monitors the saturation of the filter cartridge(s) by measuring the moisture level in the molecular sieve and provides a timely indication when a cartridge replacement is required – either on the display or via the control unit. Once saturation is reached, the system automatically shuts down the unit. The B-SECURUS filter monitoring system can only be used in conjunction with the P 41, P 61, or P 81 filter systems, as well as the external BAUER filter systems.
First-stage separator
For operation in humid ambient air, such as in tropical regions or when handling moist gases, a separator is recommended after the first compression stage. It reliably discharges the increased amount of condensate and minimizes its entry into the compressor oil.
Intermediate pressure gauge
Analog pressure gauges are installed at appropriate points of the compressor system and allow for easy monitoring of operating pressures. They support diagnostics and simplify maintenance work on the system.
Trolley set
The trolley set enables easy and effortless transport of mobile compressor units. Equipped with pneumatic wheels, it ensures maximum mobility.
B-CONTROL III
The B-CONTROL III is the premium control system for complex applications. Its 7-inch touchscreen display provides a user-friendly visualization of all operating data. Features such as a data logger, USB interface, Remote HMI, and protocols including OPC UA, Modbus, and CAN bus are integrated. The control system supports up to four compressors in a network and can be expanded flexibly.
