Technology

Thanks to their pioneering modular systems, nitrogen is produced according to specific demand, which saves cost for the user.

The nitrogen generator has a master channel with one to eight modules. You can extend it for another three parallel channels, again with one to eight modules. Flexibility is our top priority, which is why you can always customise your nitrogen generation within the parameters of:

•  Performance
•  Delivery quantities (1.3 to 265.8 Nm³/h)
•  Degree of purity (up to 5.0 i.e. 99.999%)
•  Efficiency (maximum efficiency is ensured thanks our pressure swing adsorption process)

Maximum efficiency: our pressure swing adsorption process produces oxygen with optimum efficiency.

These high quality features characterise our oxygen generators:

•  Purity: The produced oxygen has a stable purity of between 90 and 95 percent
•  Flexibility: Delivery quantity of 2.49 to 46.8 Nm³/h and adjustable oxygen purity
•  Risk-free: Storage in high-pressure vessels is no longer necessary
•  Economical: There are no losses through evaporation and, due to our high quality components, little maintenance is required

Our PO Series combines durability with  high-performance. With this Series we have developed highly efficient, low-maintenance and compact air compressors with a low noise level. Due to its modular design concept, diverse and targeted results can be achieved.

Completely oil-free compressed air

Sensitive industries and areas where oil-free compressed air is essential will benefit from our continued efforts to optimise even the smallest of details in our oil-free compressed air systems. In our PO Series, the complete absence of refrigerant throughout the system enables entirely oil-free compressed air production. The alternative to the refrigerant? Specially coated pistons and piston rings, with specially designed cylinder liners and hermetically-sealed bearings.

Other advantages of the PO Series are:

•  The narrow and compact lightweight design offers multiple applications
•  The light and enclosed cooling air-flow hood made of heat resistant ABS plastic contributes to improved safety at work. It fully complies with EN 1012-1 "Safety Requirements for Compressors"
•  Due to a design that is focused on low wear, the compressors are virtually maintenance-free. For example, we have minimised the low piston speed to 3 m/sec vibration – thereby lowering temperature and wear. The piston and cylinder benefit from this development and have a longer life cycle
•  The PO Series meets the requirements of the RoHS Directive (2002/95/EC) *

* RoHS = Restriction of (the use of certain) Hazardous Substances

28 different air compressors for individual requirements

A total of 28 different variants within the PO Series are available. Four examples are:

•  PO 8 L: "PO" stands for "Piston Oil-free" and "L" for "Line". This is, with this base unit, an oil-free, direct-coupled piston compressor with an engine output of 8hp
•  PO 8 LR: This compressor has a separate storage container for the compressed air (R = Receiver)
•  PO 8 LDR: This is an oil-free piston compressor in combination with a compressed air tank and a dryer (D in this case stands for Dryer)
•  PO 8 LTR: This compressor is a twin system (T = Twin) with a separate container

Variants of the PO series in different industries

Typical industries where our oil-free piston compressors are used:

•  The medical and pharmaceutical industries, which have relied on BOGE quality compressed air for many years
•  Craft and paint shops, where compressed air must meet the highest quality standards and be absolutely free of oil
•  The food industry, for example when precisely matched amounts of compressed air are required for filling processes
•  In water treatment, where oil-free compressed air is used, for example, during the aeration or "bubbling" of air to support bacteria growth

With production of the compressor taking place at our plant in Grossenhain near Dresden, it really is our traditional German engineering at its finest.

The BOGE airend combines efficiency with silent running and longevity. This is made possible by individual, innovative components developed in-house:

•  Thanks to the innovative rotors with five teeth on the male rotor and six on the female rotor, there is only a small pressure differential between the chambers
•  Low power losses thanks to the silky smooth performance and the optimal design of the power ranges
•  An axial suction guarantees a higher volumetric efficiency
•  The comparatively much lower rotational speed prolongs the lifecycle and reduces not only the sound-levels but also vibrations (and consequently, efficiency losses) caused by splashing
•  Efficiency losses are minimised by the precise manufacturing tolerances
•  Durability: The largest possible high-quality bearings are chosen, which doubles the lifespan of the bearing
