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
• 6 indicates 60 Hz operation, whereas 5 indicates 50 Hz operation
• 50 - 75 indicates 50% to 75% recovery
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.
1.4 Economy and Deluxe Model Options
1.4.1 Economy Model
E-Series Economy (ECN) model water purification machines have all the features
necessary for safe, continuous production of high purity water. This assumes good
quality feed water, adequate pretreatment and regular operator maintenance, each
shift or daily, to the operation of the system.
• 50% to 75% recovery
• Multi-stage centrifugal pump, SS construction (stainless steel castings with
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
