+ Wet compression systems benefit from years of experience building water wash
+ Uses high reliability pumps & control systems
+ Line of sight injection allows much better control of the water distribution and ensures 100% water usage
+ Even when not running wet compression, efficiency and power gains are realized by having a cleaner compressor improving the ROI of the system
