Operating limits
Operating Parameters
- Maximum Temperature: 60°C (140°F)
- pH Range @ Max Temperature: 2-10
- pH Range @ Ambient Temperature: 2-10.5
Pressure
- Max Inlet Pressure: 120 PSI (8.3 Bar)
- Min Outlet Pressure: 10 PSI (0.7 Bar)
- Max Differential Pressure per Element: 18 PSI (1.2 Bar)
- Max Permeate Backpressure: 5 PSI (0.3 Bar)
