Example: E4H-21K/ECN, 230, 6, 50-75
• E4H indicates the machine series
• H indicates horizontal membrane element housing configuration
• 21K indicates the rated permeate flow in thousands of gallons per
day @ 77ºF (25ºC),(i.e., 21K = 21,000 gallons per day)
• ECN indicates Economy Model and DLX indicates the Deluxe
Model
• 230 indicates 230 VAC, three-phase voltage to starter

1.3 Machine Permeate Quality
The permeate rejection performances are as follows:
E4H machines use high rejection Osmo 415 - HR(PA) membrane elements, providing the
ultimate in high purity water.

Noryl stages)
• Base model electrical package includes NEMA-1 enclosure with a
110 VAC, 60 Hz or 220 VAC, 50 Hz single-phase control circuit; applies to
all ECN models
• Automatic inlet shutoff valve
• Pre-filter housing and 5-micron cartridge pre-filter
• Pre-filter, post-filter, primary and final pressure gauges
