- 5. GE copyright information© 2015 – Subject to restrictions on cover page SPRINT® Description SPRINT® stands for SPRay INTercooling • The SPRINT® system increases power output by injecting water into the compressor – Allows engine to run at higher firing temperature—more power – Increases overall mass flow—more power Operation • Injection of water into the HPC or LPC compressor • Water spray system operation at base load only • Does not affect requirements for reliability • Operation at ambient conditions above 2°C
