1.5 Specifications for E-Series Machines
1.5.1 Feed Water Requirements
Table 1.1
Feed Water Requirements
1.5.2 Permeate (Product Water) Flow Rate
Stated on the serial number label (assumes no permeate back pressure,
2000 mg/L TDS maximum feed concentration, and rated temperature).
To estimate permeate output with back pressure, use the formula below:
Permeate Back Pressure: Maximum: 80 psig (5.5 barg)
Permeate Outlet: 1-inch FNPT

35° - 77°F (2° - 25°C) Not to exceed
85°F (29°C) unless specifically
designed for higher temperatures
Minimum: 30 psig (2.1 barg)
