Unrivalled versatility. These two words describe in a nutshell exactly what makes AERZEN screw compressors so special: the biggest range of models; the highest number of possible modifications and the widest range of accessories. But these stages and packaged unit series have a lot more going for them, not least the development capability of the global market leader, which has been continuously working on innovations, optimisation and completion of its successful compressors since 1943.
For decades, leading packagers and industrial users have insisted upon AERZEN compressor stages and packaged units. Why? Because with their exceptional versatility these machines are the ideal solution for every application. Originally designed for compressing air, nitrogen and neutral gases, these all-round geniuses are also developing their strengths in use with special gases, in vacuum operation and in inlet pressure applications. Direct and belt-driven, dry running and classified oil-free to class 0 or with oil injection, with or without pre-inlet. Let’s put it this way: AERZEN has the right compressor for every application.
Screw compressors are perforce twin-shaft rotating lobe machines. They work on the positive displacement principle with internal compression and are so-called compulsive conveyors. This applies for all screw compressors. However, what makes AERZEN screw compressors special is that we have made reliability, ease of maintenance, user-friendliness, flexibility and energy efficiency a matter of principle. The result is a range of unique design features. Take the efficiency coefficients for example, such as the AERZEN 3+4 VML profile or the 4+6 VM profile. Compared to standard compressors they deliver an considerable energy saving. And what is the ultimate in compressor technology? That is AERZEN new E-compressors. With an increase in efficiency of around 6% they free up even more valuable potential.
