Kaeser's CSG series of oil-free screw compressors are designed to deliver the highest level of purity and reliability. With ISO 8573-1 residual oil class 0 certification, these compressors ensure that the air meets the most rigorous industrial standards. This commitment to quality makes Kaeser a trusted partner in the food and beverage sector, where we uphold ISO 22000 certification to guarantee superior food safety, product quality, hygiene, and process reliability.
Our groundbreaking CSG systems feature a newly developed screw compressor block with SIGMA PROFILE technology. This advancement represents a significant leap forward in both purity and efficiency. The compressor block is coated with a heavy-duty PEEK layer—a high-performance plastic polyetheretherketone fired twice at over 400 °C and is therefore highly temperature-stable. The coating has outstanding abrasion resistance and a strong non-stick effect.

Additionally, our oil-free screw compressors can be paired with the i.HOC rotary dryer, which ensures a consistent supply of high-quality compressed air while operating in an improved energy-efficient manner. This not only reduces operational costs but also minimises environmental impact.
