BLUE LINE: Innovative Water-Injected Oil-Free Compressor Family
The perfect solution for professional users, guaranteeing clean compressed air!
The BLUE LINE oil-free compressor family, launched in 2020, was specifically developed for manufacturing technologies requiring clean compressed air. Market demands are increasingly moving toward oil-free solutions, as required by the pharmaceutical, food, chemical, automotive, and brewing industries, among others. The series is available in power ratings ranging from 7.5 kW to 200 kW.
Perfect Purity and Outstanding Energy Efficiency
Water-injection technology provides a higher level of purity and energy advantage:
- 100% Oil-Free Guarantee: No oil contamination enters the compressed air under any circumstances.
- The compressor meets the strictest ISO Class 0 requirements, including silicone-free operation.
- Thanks to water cooling, the compression is near-isothermal, making the unit significantly more energy-efficient, as it does not require intermediate cooling like dry compression technologies.
- The water essentially washes solid contaminants out of the compressed air.
Innovative Block Design and Reliability
This modern-design block enables more reliable operation and significantly more cost-effective overhaul than conventional oil-free alternatives.
Technology: Single-stage oil-free screw compression with one main rotor and two gate rotors on the sides.
Clean Internal Design: The compressors are manufactured with completely stainless steel internal piping to achieve maximum air purity.
Stability: Ensures extremely balanced, pulsation-free compressed air production thanks to the symmetrical design.
Reliability: Contains far fewer bearings, seals, and gears than dry compression solutions.
Availability: Available in both fixed-speed and variable-speed configurations.
