Res-Kem supplied, to a new nanotechnology center in Philadelphia, an ultrapure water system. The start up will commence this Monday. The system is designed to produce water with three different qualities to supply:
- 10 gpm to process cooling equipment
- 40 gpm to laboratory benches and humidification equipment
- 75 to 125 gpm to recirculation loop feeding process tools
 |
| Ultrapure Water System Produces a Maximum of 125 gpm of UPW |
