Преимущества и инновации
High energy efficiency in continuous operation
Our screw compressors for biogas and CO₂ compression are designed for economical continuous operation. Modern manufacturing processes and efficient compressor geometries enable high performance with low energy consumption. This reduces operating costs and supports sustainable, resource-efficient production.
Exceptionally smooth and low-vibration operation
An optimized coupling concept allows the screw compressor to operate with very low vibration, significantly reducing noise levels. At the same time, mechanical loads are minimized, increasing the service life of both the compressor and connected systems.
Individually configurable for your application
Thanks to the modular design and a wide range of options, our screw compressors can be precisely configured to meet your requirements. You receive a solution that is accurately matched to your process.
Fast service and reliable spare parts supply
Our service concept ensures that your compressor system remains permanently available. With original spare parts, short delivery times and trained technicians, downtime is minimized and long-term system operation is secured.

Details & Features
BAUER screw compressor systems stand for top quality, durability, and maximum efficiency. With a pressure range of 6 – 20 bar, they are perfectly designed for the reliable compression of CO₂ and biogas. This makes them an energy-efficient and sustainable solution for demanding industrial applications.
The typical scope of supply includes the compressor with motor, base frame, intake section, discharge section, oil cooling, as well as software cards with display and frequency converter for seamless integration into the customer’s control system.
ROTORCOMP EVO screw compressors
Rotorcomp's EVO screw blocks for biogas are characterised by their extremely high efficiency thanks to the wear-free ROLLING PROFILE® rotor and offer a long service life and modular design, which is ideal for biogas compression systems in particular.
Oil cooling
Oil/water heat exchanger located in the oil circuit, which maintains the oil at a stable temperature of around 90°C.
Software cards, display and frequency converter
These are supplied separately as standard and integrated into the overall control system by the customer.
Options
Heat recovery
The optional heat recovery system utilizes the waste heat generated during compression and efficiently provides it for heating or process applications. This reduces energy costs while simultaneously increasing the sustainability of your system. Up to 80% of the drive power can be recovered in the form of heat.
Complete unit control
The optional complete plant control enables central monitoring and management of all relevant processes of your screw compressor. This gives you full control at all times, optimizes operation, and increases the overall efficiency of the system.
Gas cooling (for water-cooled systems)
The gas cooling option reliably reduces the temperature of the compressed biogas, thereby protecting downstream system components. This ensures efficient, safe, and continuous plant operation.
Fine oil filtration
The fine filtration (oil removal) option ensures the reliable separation of oil from the compressed gas. This guarantees high gas quality and protects downstream processes. A residual oil content of up to 0.003 mg/m³ can be achieved.
Tanktdatenerfassung
Wird die Min-Markierung des Ölstands erreicht, erscheint eine Warnmeldung in der Steuerung. Diese Option ist besonders für den Dauerbetrieb empfehlenswert und erhöht die Betriebssicherheit der Kompressoranlage durch frühzeitige Information über kritische Füllstände.
