E-Series L
Large Reverse Osmosis Machines, 3 to 23 m 3 /hr
Figure 1: E4H-CE-L, 3 to 7 cubic meters per hour
Figure 2: E8-CE-L, 9 to 23 cubic meters per hour
GE Water & Process Technologies has more than 30
years experience in designing and building high
quality reverse osmosis systems. Our E-series RO
machines (Figures 1 and 2) are designed for durable
operation, high quality product water production,
easy installation and straightforward control.
E-Series-CE-L machines are designed in 2 versions
of operating temperatures: 25°C and 13°C (CW).
