be supplied by others)
140 KVA 107 KVA 276 KVA 209 KVA
Typical Power consumption 2 – 4 kWh/1,000 gallons of product water
Performance, number of stages and cell pairs, recovery and power consumption are dependent on inlet feed water
quality and temperature. A Watsys projection must be completed by an authorized GE Water & Process Technologies
design representative for proper system design & for any performance guarantee to be provided.
