Utilize energy potentials

Thanks to open system integration, modular basic components as well as variable mechanical and electronic interfaces, the oil-free two-stage Aerzen screw compressors of the 2C series offer the highest functional adaptability for different drive and control concepts. In combination with tailor-made systems for heat recovery, the customized compressed air units become true energy-saving masters and part of a system solution.

A large amount of heat energy is generated during the production of compressed air. If this process heat is utilized by means of heat recovery for further operating processes such as water heating, drying processes or preheating of burner air, considerable energy savings, emission reductions and cost reductions can be achieved.

With high-performance compressor technology and customized systems for heat recovery, Aerzen offers exactly the right answer. The result: maximum resource efficiency and economy. An example are the two-stage screw compressors of the series 2C with heat recovery from the house of RKR Gebläse und Verdichter GmbH, a 100% subsidiary of Aerzen and the specialist for two-stage compressor solutions in the group of companies. These two-stage compressor solutions become an innovative system solution of the customer application by the Aerzen customer consulting and engineering competence of RKR.

From compressor to system solution

While the traditional machine perspective is "only" focused on inlet and outlet conditions, a system solution adds other perspectives and requirements - namely the customer's overall process. In this case, the focus is on the thermal energy contained in the compressed gas and the question of how this energy source can be used outside the machine technology for the environment or even a process engineering process. The art here is to create an optimum of functional integration, cost-effectiveness and efficiency while dissipating the greatest possible heat energy.

Making sensible use of thermal energy

The solution is an intelligent functional interconnection and control of several water coolers integrated in a tailored system technology and control architecture. This means that a large part of the electrical drive energy converted into heat during compressed air generation can be used, for example, for temperature control in the production process without having to access additional energy sources. This enables considerable energy savings, improved cost-effectiveness, increased energy efficiency of the overall system, and thus an important contribution to the climate and the carbon footprint.

Maximum system performance thanks to customized compressed air solutions

The air- or water-cooled compressors of the 2C series supply oil-free and absorbent-free compressed air in the pressure range from 4 to 11.5 bar (g) and are designed for volume flows from 166 m³/h to 9,300 m3/h. The modular concept guarantees a high degree of functional adaptability for different drive and control concepts and ensures maximum flexibility in adapting to application-specific requirements and customer-specific process conditions. In addition to functionally tailored solutions, individual designs for particularly noise-reduced applications, outdoor installations or heavy-duty container configurations are also used.
