Advantages that pay off
for you every day

It is not only the outstanding delivery rates that testify to the perfect interplay of innovative functional principle, intelligent design and high-quality workmanship. Also in terms of efficiency and the holistic cost view, the SO-3 series achieves top values. Its technologically sophisticated and at the same time maintenance-friendly construction not only makes the environmentally friendly, reliable production of oil-free compressed air particularly sustainable, but also has an immediate cost-minimising effect.

The compressor stage of the BOGE SO-3 series is an in-house development. The compressor stage features high-quality, generously dimensioned bearings and operates at 40% lower speed than its predecessors. Low compression temperatures and reduced wear increase service life, and the flow-optimised rotors guarantee — at the lowest specific power — high delivery rates as well as outstanding efficiency values!
Motors of energy efficiency class IE4 promise maximum efficiency. With an optional frequency converter, energy consumption can be reduced even further.
The highly efficient cooling system relies on extra-large coolers made of high-quality stainless steel and a cooling principle that reduces the risk of contamination by maintaining a constant water velocity. The low compressed air outlet and compression temperatures as well as effective condensate separation also contribute to high energy efficiency. To ensure cooling of the hot compressed air to a consistently low temperature, the principle “air through the pipes” applies with a constant flow velocity.
The measures for consistently vibrational and stress-technical decoupling of many components have multiple effects — noticeably reduced pulsation vibrations and significantly less wear. Not to mention the surprisingly quiet operation.

Why the SO-3 Series

Engineered for the lowest
total cost of ownership

Guaranteed Oil-Free
Innovative compressor technology operating to very fine tolerances with perfect sealing between the oil system and the compression chamber. Oil-free air guaranteed — suitable for the most demanding sensitive applications.
In-House Compressor Stage
BOGE-developed compressor stage running at 40% lower speed than predecessor designs. Flow-optimised rotors and low compression temperatures combine to deliver outstanding efficiency and extended component life.
IE4 Motor — Premium Efficiency
IE4 Super Premium Efficiency motors as standard — the highest energy efficiency class available. Combined with an optional frequency converter, energy consumption can be reduced even further for variable-demand applications.
Heat Recovery up to 94%
Up to 94% of the energy required for the compression process can be recovered and made available for other uses — process water heating, space heating, or other applications. A significant contribution to reducing overall energy costs.
Stainless Steel Coolers
Extra-large coolers manufactured from high-quality stainless steel, maintaining constant water velocity to reduce the risk of contamination and ensuring consistently low outlet temperatures throughout continuous operation.
Individually Configurable
From heat recovery to frequency converter to hot gas outlet for a warm-regenerating DAV-2 adsorption dryer — the SO-3 supports a wide range of configuration options for highly specific application requirements.
Available Options

Individually configurable
down to the last detail

Given the many options available, there is certainly no shortage of choices. Contact Tranco Tech for a configuration recommendation tailored to your process and energy requirements.

Heat Recovery (up to 94%)
Recover up to 94% of compression energy for process water, space heating or other applications, dramatically reducing total energy costs.
Frequency Converter (VSD)
Optional frequency converter for demand-matched operation — further reducing energy consumption in applications with variable compressed air demand.
DAV-2 Adsorption Dryer
Hot gas outlet option for connection to a warm-regenerating DAV-2 adsorption dryer, achieving very low dew points without additional regeneration energy.
Compressed Air Treatment
Full range of downstream treatment options — filtration, drying, condensate management — available to meet specific air quality requirements per ISO 8573-1.
Typical Applications

Reliability counts —
wherever oil-free air is essential

Whether in the pharmaceutical, food or beverage industries, in mechanical engineering or industrial paint shops — wherever larger quantities of high-quality, oil-free compressed air are required, the BOGE SO-3 series comes into its own.
