Taking Efficiency To A New Level

Minimal Power Consumption, Extremely Short Downtimes

Effortless maintenance, and a long-life expectancy – the BOGE S-4 series has what it takes to outshine all screw compressors in the same class. From the outset, the new models offer the most efficient screw compressors in their specific segment. At the heart of every S-4 is the BOGE “IntegrateDrive” Airend, which was developed in-house. This features fully integrated gears or direct drive with speed control.

Practical By Nature – Particularly When It Comes To Maintenance

All Sound-insulating Panels On The S-4 Can Be Removed For Fast Access In Next To No Time

Regular maintenance work can be performed from just two sides: Changing the oil and separation cartridge takes place at the front of the machine, likewise the suction regulator, minimum pressure valve, and oil regulator. Only the oil, air, and primary intake air filters are changed from the side.

SO And SOF – Changing The Oil-free Game

Innovative Down To The Last Detail – Available From 45 To 355 KW

Precise engineering for clean results: The SO series impresses with its intelligent design, high-quality workmanship, and innovative functional principle. Its technologically mature and maintenance-friendly design makes the production of oil-free compressed air safe, reliable and economical. Based on site conditions, you have the option of fixed or variable speed drive and air or water cooling.

Optimally Placed Intake Filter

The principle of pre-separation and subsequent fine separation of the intake air ensures optimal cleaning of the intake air and minimum wear at the Airend in all SO models. The intake filter – mounted at the coolest point – guarantees high delivery rates and low specific power.

Powerful Drive Motor

In the interest of maximum efficiency, only highly efficient IE4 motors are used – optionally with an automatic, demand-controlled relubrication device. All drives can be equipped with frequency converters to further reduce energy consumption.

Effective Sound Insulation

How to achieve an effective reduction of the sound level? Through the consistent use of unique sound insulation material with a higher degree of good adsorption in the relevant octave bands

Tried And Tested Airend

Developed in Germany, the BOGE Airend impresses with high-quality, generously dimensioned bearings, possible minor tolerances, and effective sealing between the oil system and compression chamber. Everything for absolutely oil-free compressed air and high delivery rates with the lowest specific power.

Optional Heat Recovery

The fantastic thing about the BOGE heat recovery solution: 94% of the supplied energy can be used for the heating system, as service water, or as heat for industrial processes. This saves energy and cash and applies to all water-cooled compressors.

Consistent Vibration Recovery

The vibration decoupling and the low-stress design of the compressor and cooling sections, as well as other components, not only result in a further reduction of pulsation vibrations and the sound level: it also guarantees less wear and longer service life of the components.

Low-Maintenance Cooling Concept

In the interest of long service life, the coolers have been oversized and are constructed from high-quality materials. To ensure that the hot compressed air is cooled to a constant low temperature, the cooling system has been designed to provide continuous water velocity through the pipe work, resulting in less contamination and, thus, improved efficiency.

Maximum Condensate Separation

Only effective condensate separation with intelligent flow guidance creates the prerequisite for optimum cooling. This guarantees high energy efficiency with minimal pressure losses.

Oil-free And Safe

From the innovative compressor technology, which operates with the smallest possible tolerances, to the effective sealing between the oil system and the compression chamber to produce oil-free compressed air wherever the highest compressed air quality is required, there are no compromises with the SO series.

Amazingly Economical

Both the type of intake and the intelligent routing of the cooling air and the effective cooling by heat exchangers ensure a high delivery rate with the lowest specific power. The air-cooled versions use an inter-cooling system developed by BOGE. All this provides extremely economical, cost-saving compressed air generation.

More Efficient Through Frequency Control

All machines in the SO series are available in a frequency-controlled version; the frequency converter is housed in the switch cabinet to save space. This allows energy savings to be achieved in several ways:

More Efficiency Through Temperature Optimization

Thanks to effective inter-cooling by a frequency-controlled exhaust fan, the intermediate temperature of the air-cooled compressors of the SO series is optimized. In this way, the inlet temperature to the HP Airend remains constant, and the energy consumption is minimized – the associated increase in efficiency is impressive.
